Wade Miley's Winning Combo: Great Command And Great Framing

Russell Martin is many things — a Canadian, a three-true-outcomes hitter, a strong defender — but above all else, he's an excellent judge of pitch location. Since 2007, the first year of PITCHf/x data, Martin has swung at 20.3 percent of pitches outside the strike zone, ranking 27th among 567 qualified hitters. (For what it's worth, he's also swung at 59.2 percent of pitches inside the strike zone, which is 124th in that sample.) Maybe it's because he plays behind the plate, or maybe it's just an innate talent; whatever the reason, he can usually tell the difference between balls and strikes.

We can understand, then, why he got a little miffed here:



With the Jays trailing the O's 5-3 in the sixth inning, Martin worked the count to 2-2 against Wade Miley. The left-hander uncorked a sinker that fell right on the edge of the PITCHf/x-defined strike zone, and though Martin checked his swing, Brian Knight rung him up. It was the eighth strikeout of the night for Miley, continuing an unforeseen run of dominance from the Orioles starter.

Heading into the year, most of us didn't expect much from Miley. FanGraphs' Depth Charts projected the southpaw to put up a 4.48 ERA and 4.34 FIP over 169.0 innings — the marks of a wholly uninspiring, mid- to back-of-the-rotation arm. Yet over his first three starts, Miley has earned a sterling 1.89 ERA and 3.15 FIP. While his walk rate (11.1) is elevated and his ground ball rate (48.7 percent) is in line with his career average, he's struck out 33.3 percent of opposing hitters. Even in this young season, that ranks fourth in the majors.

But wait. Looking at his PITCHf/x plate discipline metrics, we don't see much improvement from past years. If anything, Miley has performed worse in 2017:

  Year(s)    O-Swing%    Z-Swing%    Swing%    Contact%    SwStr%    Zone% 
  2011-16  30.7% 63.5% 45.4% 81.0% 8.6% 44.8%
2017 31.3% 66.7% 45.7% 81.2% 8.6% 40.7 %

Miley's whiff rate hasn't budged from past years, and he has the unsavory combination of fewer pitches in the zone and more swings in the zone. How, then, has he fanned a third of the batters he's faced?

Well, aside from fortuitous sequencing — which is to say, luck — Miley's accumulated a lot more strikes than you'd expect, based on his zone and O-Swing rates. The trend has affected each of his starts:

  Start    Pitches    Strikes    xStrikes 
  4/9    100    56    51 
  4/14    101    66    61 
  4/20    101    70    67 
  Total    302    192    179 
xStrikes = Pitches * (1 - (1 - O-Swing%) * (1 - Zone%))

Getting those extra calls has given Miley an above-average strike rate (63.6 percent) and looking-strike rate (28.1 percent). That's made him a power pitcher, of sorts, and resulted in a lot of weird looks like the one Martin showed above.

So does Miley stand any chance any chance of keeping this up? Or will his greatness fade away, like so many other early-season success stories? (Remember April 2016 MVP Joey Rickard?) He probably won't have a higher strikeout rate than Max Scherzer by the end of the year, but Miley has a couple of factors working in his favor.

Baseball Prospectus debuted a metric called CSAA in February, which isolates a pitcher's ability to get called strikes as a proxy for his command. I'll let BP explain the details:

A pitcher with good command should be more predictable for the catcher—their pitches often end up in the locations, and with the movement that the catcher expects. This skill results in easier receiving for catchers, and additional called strikes for the pitcher. Once we aggregate the data cross thousands of pitches, CSAA is able to tell us whether a pitcher is reliably hitting his spots.

By this metric, Miley's always excelled. This year, though, he's taken things to another level:


As of this writing, Miley's 4.59 percent CSAA ranks third in the majors, trailing fellow left-handers (and past Cy Young winners) Dallas Keuchel and Clayton Kershaw. For whatever reason — maybe he's better with his sinker, which he's used more often this year — Miley's command has taken a huge leap forward in 2017, and his strikeout rate has spiked in turn.

But command, I'd argue, is not the most significant variable at play. As noted, Miley's command is nothing new (albeit not to this extent), yet he's never overperformed his expected strike rate like this. The bigger factor in his 2017 success seems to be the second half of the called-strike tandem — the man behind the plate.

While the Orioles brought in Welington Castillo and his lead glove to start at catcher, he hasn't manned the position every day. Caleb Joseph has gotten the nod four times this season — on April 9, 14, 20, and 22. If you've been checking the dates in that table above, you'll notice something: Joseph has caught all 19.0 innings Miley has thrown in 2017. Needless to say, it's shown.

In case you went into a coma during the mid-aughts to avoid another miserable year of Orioles baseball and just woke up, I'll fill you in on the secret around Baltimore: That Caleb Joseph fella? He's pretty good at framing. This year, he's posted a .029 CSAA, the highest in the majors. Since his 2014 debut, he's saved the Orioles 27.1 runs in less than 2,000 innings.

Miley certainly appreciates what Joseph has done for him, as he explained to PressBoxOnline's Rich Dubroff:
"Not to knock at Welington. I've thrown to him. He's outstanding as well," Miley said. "Something about Caleb from spring training. I don't know what it was. I know he works hard back there for me. We've got a good thing going right now. 
"As a pitcher, you've got a catcher back there working really hard for you, and you see that. You kind of build off of that, build off the energy you see him giving, and you go from there."
Whether "works hard" is just boilerplate athlete talk or a subtle nod to Joseph's framing prowess/dig at Castillo's framing ineptitude, we'll never know for sure.

Earlier in that piece, Buck Showalter swears there's nothing to the Miley/Joseph pairing, and that he doesn't believe in the idea of personal catchers. If Castillo catches Miley more often, it'll certainly put a dent in his numbers; still, it shouldn't sink him entirely. Joseph has worked with some pitchers more than others — last year, he caught a large chunk of Ubaldo Jimenez's innings, more so than any other Orioles regular:

  Pitcher    Joseph Innings    Innings    Joseph% 
Kevin Gausman 27.0 179.2 15.0%
Chris Tillman 23.2 172.0 13.8%
Ubaldo Jimenez 57.2 142.1 40.5%
  Yovani Gallardo  25.0 117.1 21.2%
Dylan Bundy 32.0 109.2 29.2%

Some catchers seem to have a rapport with a given pitcher (or are just better at catching), and while Showalter understandably doesn't want to disrupt his schedule to accommodate that, he'll tweak things so guys like Jimenez and Miley can throw a few more innings to their backstop of choice. That helped Jimenez a couple of years ago, and it could work in Miley's favor this season.

As Martin and the Blue Jays have spiraled out of contention, the Orioles are, once again, flying high in April. No team in the American League has a better record than the Birds, and Miley has been the team's second-best starter to this point (can't knock Bundy, I'm afraid). His ERA won't remain below two for the entire season, or below three, but it's clear that he's not the 6.17-ERA starter we saw in the second half of 2016. Someone with command like this, who pitches to a catcher like Joseph, is bound to rack up strikeouts and keep runs off the board.

Why WAR-Based Systems Underestimate Elite Relievers

People using WAR based systems to value players typically think that relievers are overvalued by baseball clubs.  Way back in 2010, an article printed on Fangraphs made the following claim:

WAR, as you probably know, doesn’t think much of relief pitchers. The very best relievers in the game are generally worth +2 to +2.5 wins over a full season, or about the same as an average everyday player. This has caused quite a few people to state that WAR doesn’t work for relievers, because the results of the metric don’t match what they believe to be true about relief pitcher value. I think it works just fine.
While the quality of their work is very high, the quantity is low, which limits their total value. It’s nearly impossible to rack up huge win values while facing less than 300 batters per season. Yes, each of those batters faced are more critical to a win than a regular batter faced, but this is accounted for in WAR.

Since that article, there appears to be a consensus that the WAR based systems still seem to undervalue relievers compared to actual baseball clubs, but people are now trying to understand the reasoning for that gap. Ron Arthur of 538 noted that teams with a good bullpen or more likely to hold a one-run lead and therefore made a hypothesis that this may be a reason why relievers seem to be overvalued by front offices relative to the sabermetric consensus. An article in Baseball Prospectus asked why teams seem to be willing to spend millions on relievers when WAR(P) tells them that spending on relievers is a mistake. The author argues that WAR(P) doesn’t do a good job measuring reliever value and that Win Probability Added (WPA) helps explain teams reasoning. Finally, a more recent article in Fangraphs notes that there’s a sizable and growing gap between the public’s valuation of elite relief arms and the industry’s valuation.

I think the reason why WAR-based systems struggle to quantify the value of relievers is because of a focus on value over replacement rather than value over average. If one focuses solely on value over replacement, than a 1 WAR starter who pitches 200 innings is just as valuable as a 1 WAR reliever who pitches 60 innings. In this scenario, since a replacement player by definition produces 0 WAR, each player contributed 1 WAR more than a replacement player. And since a replacement level starter is better than a replacement level reliever, it makes sense to argue that the 1 WAR starter is even more valuable than the 1 WAR reliever.

However, the results are different if one focuses on value over average. Suppose there are two pitchers on two teams; one pitcher produces 2 WAR over 60 innings and another that produces 2 WAR over 200 innings. If we presume that each team’s pitchers throw 1450 innings total and that the average team produces 14.3 pitching WAR, then the team with the pitcher that threw 60 innings needs to earn 12.3 WAR over 1390 innings to be average while the other team needs to earn 12.3 WAR over 1250 innings to be average. This example illustrates how two pitchers can earn the same amount of WAR, but one pitcher can help his team more than the other pitcher.

Focusing on value over average is probably a better strategy than focusing on value over replacement. Each year, pitchers earn roughly 430 fWAR split out among all 30 teams. From 2000-2016, there has been only one team with negative pitching WAR. Ultimately, most teams have a large population of pitchers that are above replacement and therefore need to consider not only how best to maximize WAR but to minimize innings pitched. Innings are a finite constraint that aren’t given enough consideration in WAR-based systems.

Recently, maybe even this week, Fangraphs updated its methodology for how to determine pitching WAR. It’s complicated but a simple and incomplete version of their method is that they determine Wins Per Game Above Replacement (WPGAR), multiply this by the innings pitched and then throw in a few more adjustments. For our purposes, the only relevant fact is that their methodology focuses on replacement rather than average.

In order to determine a Wins Above Average metric, I determined that on average from 2010-2016, an average pitcher earns 1 WAR per 101 innings. Therefore, to determine Wins Above Average, I take a pitchers WAR and subtract from it (Innings/101). For a more complicated Wins Above Average metric, I’d use Fangraphs methodology for determining wins above average and see whether our numbers are similar, but I didn’t learn about their updated methodology in enough time to perform the necessary calculations.

This metric is friendlier towards elite relievers than Wins Above Replacement. For example, from 2010-2016, 2016 Zach Britton ranks 402nd in WAR but 184th in Wins Above Average.
There aren’t so many surprises in the top ten pitchers. The absolutely amazing Clayton Kershaw is ranked #1 despite throwing only 149 innings. Rich Hill ranks 10th with a strong 110 innings. But in the next top 10 pitchers, there are relief pitchers Jansen, Miller and Betances. Chapman is ranked 21st and Britton is ranked 25th.

I built a basic model converting Wins Above Average to projected salary to see how elite reliever salaries might compare with this metric instead of using Wins Above Replacement. The model could use some improvement and isn’t ready for primetime, but it seemed to indicate that relievers might be 30-40% more valuable using Wins Above Average instead of Wins Above Replacement. If so, this could help explain why elite relievers are receiving higher salaries than WAR-based systems suggest.

WAR-based systems presume that players replacing other players are only at replacement level. This presumption means that relievers that can earn 2 WAR while throwing in just sixty innings are valued equally to starters that earn 2 WAR if they throw in 200 innings. Until WAR-based systems can find a way to take production over a limited period into account, it seems plausible that they will continue to underestimate the value of elite relievers.

Trey Mancini and the Audacity of Small Samples

Trey Mancini is, as of April 18 and through 39 career plate appearances, running a wRC+ of 282. Barry Bonds had a career mark of 173. He has a career wOBA of .539. That slacker Babe Ruth? A mere .513. He has more extra base hits in his career than he does singles. Take that every player ever! If he retired today, he'd leave with a career batting average higher than every player in history not named Ty Cobb (assuming we got rid of minimum plate appearance numbers, but only for Mancini). In short, he's an absolute beast.

Well, ok, maybe those comparisons are a little crazy. Not unlike Mancini's start! He's been about as great as you could ever expect someone to be, especially considering that he was never ranked as a top prospect and is learning to play a new position in the Majors. While he may not end up beating Babe Ruth's career wOBA, he's already done more this season than many would have thought back in November.

So what's driving this early career success? Well, that's a little difficult to discern. Oh, wait, no it's not. 70% of his fly balls have been home runs. He's on pace to destroy every offensive record in baseball history because, of the ten times he has hit the ball in play and in the air, seven of them have been home runs. This is both amazing and utterly, ridiculously unsustainable.

Of course, we all know that, or at least we should. But it's not like Mancini is only hitting wall scrapers. According to Statcast, he has the tenth hardest hit ball of the year (the rocket he launched against Ben Taylor of the Red Sox), so we know that he has the capability of squaring up Major League pitching. Here's the problem: other than the homers, he isn't exactly tearing the cover off the ball. JJ Hardy has a higher average exit velocity than Mancini this season and only 38% of Mancini's balls in play are considered "hard hit." He is hitting line drives at a below average rate and and has hit the ball on the ground 50% of the time. He has also continued his career trend of not walking much and striking out a ton, though this certainly isn't a barrier to playing for the Baltimore Orioles.

What does all this mean? Well, it means that, first and foremost, it's April. Weird things happen in April and September, and those are the only months that Mancini has worn an Orioles uniform in meaningful games. The home run pace will absolutely fall off, and probably very soon, though he has likely quieted at least a few critics who questioned his bat speed and swing earlier in his career. When the homers do inevitably stop coming at such a furious pace, however, it's fair to question exactly what the O's have in Mancini.

Certainly, the team showed confidence in him by bringing him north from Florida and playing him nearly every day in the two weeks of the season, but it's worth noting that the O's didn't exactly seem ready to make a commitment to him as a cornerstone of the team prior to 2017. Despite tearing up the minors and winning the Orioles' Minor League Player of the Year award in 2015, the O's signed both Chris Davis and Mark Trumbo to long term deals, guys who will occupy Mancini's most likely long term defensive positions for the conceivable future. The fact that he has been at least adequate in the outfield has to be encouraging, but it seems hard to believe that this was in the long term plan considering that he didn't play a single game in the outfield in 2016.

Of course, circumstances have a way of changing plans. Mancini's great start should, at the very least, earn him the right to stay with the big league club for the foreseeable future. Even if he's not Ruthian the rest of the way, he could be a major asset to a team that needs one.

After the Goldrush: Orioles may regret not dealing their closer at the peak of his value

The Orioles’ young season received an early blow this weekend.  Ace closer, Zach Britton, was placed on the 10-day DL after experiencing pain in his throwing arm.

That sounds dire, but quotes emanating from Camden Yards have been optimistic.  As of this writing, Britton has been diagnosed with a “forearm strain” and will not receive an MRI.

The O’s will shut the lefty down for a week or so and see how his body responds.  Expect the club to proceed super-cautiously with the 29-year-old lefty.  The last thing they want is for Britton to blow his UCL while compensating for another injury.

So, while the initial news is good, the long-term prognosis is still a bit cloudy.  It offers a preview into how tenuous the world of relievers can be: hero today, gone tomorrow.

For every Mariano Rivera, there are five or ten other guys with electric stuff whose arms simply disintegrated.  Savvy organizations, such as the early-2000s Oakland A’s, recognize this and ship those guys out while their “stock” is high.

As history has shown, the returns for these guys can be fantastic – franchise-altering even.  It’s not to say that the Orioles would be better off without Britton, but he may be more valuable as a trade chip.

Worse, they may have missed their chance to cash in for the highest return.

Let’s rewind to last December’s winter meetings.  Baseball had just witnessed the postseason, and the birth of a new age of enlightenment.

Indian’s manager, Terry Francona led his team to the precipice of a title – in large part to his shrewd and aggressive deployment of relief pitcher, Andrew Miller.  On the other side of the field, Joe Maddon’s Cubs traded for Aroldis Chapman and won it all.

As for Britton, all he had done was put up his most-dominating season to date.  Here is a snippet of his excellence:

67 innings, 2-1, 0.54 ERA, .863 WHIP, 47 saves, 9.9 K/9, 2.5 WAR

Saves aren’t a sexy statistic to the analytic community, but elite closers still hold some “ooh-ah” currency for front offices.  The Dodgers, under the whip-smart direction of Andrew Freidman, just spent $80 million to retain the services of reliever Kenley Jansen.

Britton, who leads MLB this season with five saves, is tied with Tom Gordon for the second-longest consecutive saves streak with 54 (30 behind record-holder Eric Gagne).

His legend only seemed to grow, with his infamous non-usage in the 2016 AL Wild Card Game.  So, why trade such a valuable commodity?  The answer lies in the word “valuable.” 

Despite his age, he still has one more arbitration year left before he is eligible for free agency.  Two, full seasons of dominance from Britton would have been an enticing proposition for a team that needed a closer but was less-willing to make long-term commitments.

Teams are reticent to give up their best prospects, these days, but they might be more willing after seeing the returns Cleveland and Chicago got.  Meanwhile, the New York Yankees are still counting the king’s ransom they received for Chapman and Miller:

Chapman trade:
Gleyber Torres SS
Adam Warren RHP
Billy McKinney OF
Rashad Crawford OF

Miller trade:
Clint Frazier OF
Justus Sheffield LHP
Ben Heller RHP
J.P. Feyereisen RHP

Not every player on this list will become a major league regular, much less a star.  But, they (most-specifically Torres and Frazier) represent something everything organization covets: upside.

As my collegue Nate Delong highlighted, the Orioles aren’t exactly bursting with minor league depth.  The big league roster features aging players at key positions, so the time is now for them to be developing the next wave of stars.

Any time you can trade a reliever for starting, position player, it’s a win.  Position players appear in more games and are thus worth significantly more WAR over their careers than all but a handful of closers.

Britton was sublime last year, but even he was due for some regression, as evidenced by a 1.94 FIP and a .230 BABIP.  That’s certainly been true, so far.

It’s a tiny, sample size, but he has looked hittable (10 hits allowed in 7 frames of work) and has seen his walk rate increase (3.86 BB/9 versus 2.42 last season). 

It is unknown whether these struggles were due to the injury or not.  Sometimes, closers become stale fruit overnight.  Britton wouldn’t be the first, Oriole’s closer who experienced success, only to crash and burn his way out of town (see Johnson, Jim).

And, it’s not as if Baltimore didn’t have a perfectly-capable replacement, waiting in the wings.  That’s Brad Brach, whom ESPN called “baseball’s most underrated reliever.”

Buck Showalter stopped short of naming Brach the replacement.  But, with other arms like Darren O’Day also struggling, its likely Brach will be the guy until Britton returns. 

The Orioles have shown they can pluck bullpen arms off the scrap heap.  Knowing they had Brach waiting in the wings, the Orioles should have worn out the speed dial on teams like the Washington Nationals, who were seeking relief help and had prospects to burn.

It also made sense, from a PR-perspective.  Trading Britton in-season would be a highly-unpopular move to fans; it gives the impression that they are giving up on the season.

However, the backlash would be quieter in the winter, when many fans are preoccupied with the NFL.  Also, any hurt feelings would be mitigated if Baltimore had received one of those Godfather-packages like the Yankees got.

Now, fast-forward to the present.  The Orioles are off to their customary fast start (56.4 April winning percentage over the past five seasons) and own one of the best records in baseball.  At this point, moving Britton is not even close to being on their radar.

Right now, Showalter and the Orioles would settle for having “Great Britton” back in the line-up.  It’s possible he’ll be back soon.  Whether he’s effective or not is another story.

Either way, it’s clear they missed their chance to leverage an incredible trade asset, at the apex of its value.

The Orioles Have Positional Depth; Lack Positional DEPTH

The 162 game, 6 month schedule of the baseball season is incredibly grueling, and as a result teams rely on contributions from more than the 25 individuals who initially make the roster out of spring training. In many cases, teams require contributions from more than the 40 players who make up the 40-man rosters. Injuries, ineffectiveness, and fatigue can play a pivotal role over the course of a long season at multiple positions, so it’s important (to the most practical extent possible) that teams fill their 25 and 40 man rosters with players who can provide adequate production at each position in the event the starter goes down, or in a best case scenario, just needs a day off. As MASN writer Steve Melewski mentioned in a recent article he posted, the Orioles have a lot of depth stashed in the minor leagues, particularly on the position player side at AAA affiliate Norfolk.

“The Orioles’ Triple-A Norfolk team is a club with a lot of experience - major league experience. The Tides have seven position players with over 300 games of major league experience: Pedro Álvarez (851), Chris Johnson (839), Robert Andino (481), Paul Janish (459), Chris Dickerson (355), Johnny Giavotella (353) and Logan Schafer (318).
Norfolk’s position players have combined for 3,799 big league games played, which is more than three major league clubs (Padres, Brewers and Reds) opened their 2017 season with. Members of Norfolk’s opening day roster have hit 289 career big league homers, 88 more than the Padres began the season with (201).”

Those paragraphs suggest the organization has a lot of depth. It’s false. Let’s start with Alvarez. After spending last season in Baltimore, Orioles fans are pretty familiar with him. He’s had a solid if unspectacular major league career to this point (career .238/.311/.449 hitter, translating to a 107 wRC+), and he’s actually a really nice player to have stashed in the minor leagues. Signing him to a minor league deal in the offseason is a great move in a vacuum. However, as is also well-known at this point, he’s best suited for a platoon DH role, and based on the make-up of the active roster, he likely sits 4th on the depth chart. Granted, he’s spending time in the minors to work on his outfield defense. But even if you think he’ll become passable in the outfield (while I have not seen him play there yet, I don’t), he’s probably going to need to hit as well as 2016 Mark Trumbo to justify a level of defense that is “not completely embarrassing”. Again, Alvarez on a minor league deal is a good player to have, and one of the better options to adequately fill in case of a rainy day, but he’s a redundant luxury to have in the organization.

Infielders

While doing a little bit of research for this post, I stumbled on something that surprised me.
I had remembered that the Braves signed Johnson to that contract, but for some reason I thought that had been completed AT LEAST 2 years ago. Anyway, that’s neither here nor there. Ryan Flaherty is the only backup infielder capable of playing SS, 3B, or 2B, so the Orioles are essentially a J.J. Hardy (somewhat common) and Manny Machado or Jonathan Schoop injury (less common) away from not only Flaherty seeing significant playing time, but one of these three players doing the same.

Career Statistics (UZR/150 for position noted after player's name)

Of all the options here, Johnson (who is actually injured at the moment) is the most accomplished player of those four. He’s a tick worse than your average hitter, is a lousy defensive third baseman, and at first glance, having him stashed in the major leagues appears like a good idea (especially if someone else is paying that salary, which according to Cot’s, is Cleveland). However, Johnson has not been anywhere near productive at the plate since 2013, when he rode a .354 BABIP to a .321/.358/.457 slash line. His offensive success appears to depend entirely on a favorable BABIP, as the 3 years where he’s had a wRC+ over 100 all involved a BABIP of AT LEAST .334. In the last 3 seasons (with about 2 seasons worth of plate appearances), Johnson’s wRC+’s have been 82, 70, and 63.

Robert Andino and Paul Janish are organizational veterans at this point who (to borrow some scouting lingo), “can pick it” in the field, but can’t “hit a lick”. And while Janish’s glove work makes him a nice veteran to stash in the minors “in case of an (extreme) emergency”, I’m not sure Andino is a viable option to consider for the major league roster at any point of the season. Although, if the Orioles are out of it by August, I suppose you could hope for an Andino call up as an excuse to re-watch this highlight, and to see if his Orioles media photo continues its natural progression.



Despite minor league success, Johnny Giavotalla hasn’t shown an ability to hit or field in the major leagues and is limited to second base, so that’s not ideal. I know what you’re thinking; “Hey, that Giavotella guy is a former prospect so at least he’s probably young and maybe has some upside”. He’ll turn 30 in July. Time comes for us all.

Outfielders

As mentioned, there is plenty of (defensively challenged) outfield depth on the major league roster, so let’s take a quick look at the minor league outfield depth.

Career Statistics (UZR/150 is the combined number for all OF positions)

I probably shouldn’t even include Michael Choice here, but as a former top prospect, I decided to throw him in. He’s not even playing regularly in Norfolk, which gives an indication on where he’s at on the depth chart. Logan Schafer has some defensive value, but not enough to make up for a non-existent bat. Of these three outfielders, Chris Dickerson looks like he could be interesting as legitimate outfield depth who can also actually play defense, but he hasn’t played in the majors since 2014. It’s worth noting as well that the majority of his accumulated fWAR came from 2008 and 2009 (those seasons were accompanied with BABIP’s of .410 and .360).

I realize that this article is likely a little nit-picky. None of these players are even currently on the 40-man roster, so they are only considered depth in theory. Additionally, every organization employs players with MLB experience in their upper minors (sometimes as actual depth and sometimes as roster-filler). And to be honest, the lack of outfield depth in AAA isn’t an issue as long as the Orioles don’t care about outfield defense (and to this point, they haven’t), since there is plenty of outfield depth in Baltimore (not even accounting for the re-signing of Michael Bourn). In my opinion, it’s the infield that is particularly concerning. After Ryan Flaherty, there isn’t a single option in AAA that should see playing time. This is where the lack of prospect depth could really hurt the Orioles. Yes, the players discussed in this article have major league experience, but they are known quantities. They offer no surprise upside that a fringe average or better prospect could provide upon their call-up. Additionally, the majority of these players have not been productive for 3 years (if ever), so I find it unlikely they would even be replacement level if called upon. So while some out there may prefer major league experience despite what I just outlined, I think we can all agree to hope for good health, so these players don’t accrue major league service time in 2017.

Notes on Alec Asher's Norfolk Start

For the first time in the 2017 season, the Orioles need a fifth starting pitcher. Chris Tillman is still sidelined with his shoulder injury, so the Orioles will reach down to AAA Norfolk and promote Alec Asher to make the start on Saturday. Asher will be on regular rest on Saturday because he last pitched on Monday, and that's probably why the Orioles chose him. It's nevertheless a fortunate choice because (1) Asher was the only Norfolk starting pitcher who hadn't had a terrible start and (2) our own Jon Shepherd's performance projection model is most optimistic about Asher than any of the other candidates.

I was the datacaster for Asher's Monday start against the Gwinnett Braves (Norfolk's home opener) and will share a few details about the start. This is only one start, and there's no guarantee that this performance is typical. I was going to also say that Gwinnett is not a good hitting team, but the Braves scored 23 runs in the next two games, so Gwinnett may be better offensively than I thought. Also, the conditions were generally favorable, with a strong wind that started out blowing out to left field but shifted toward a right-to-left crosswind.

There's nothing wrong with the basics: 4 1/3 IP, 4 hits, 0 runs, 0 walks, 6 strikeouts. He was pulled in the fifth inning after - I am guessing here - nearing a 75-pitch limit.

Asher faced sixteen batters and ten put the ball in play. It's a little concerning that only one batter hit the ball on the ground. I consider five of the ball put in play to be fly balls and four to be line drives. Two of the fly balls were hit to the right-field warning track (Pedro Alvarez was able to catch them - but that's another story) and may have been home runs with a less-strong wind. That doesn't agree with Jon's observations. I can assume that this game was an aberration - perhaps he was too pumped up for a home opener or to be with a new organization, and so his sinker may have been less effective - but it still happened.

Asher did have good control. He had 3 2-0 counts; 1 3-0 count (which was, of course, one of the 2-0 counts), 1 3-1 count, and 4 3-2 counts.

On the other hand, Braves batters were able to spoil a lot of his pitches. Fourteen of his 74 pitches were foul balls and there were six at-bats of six or more pitches. For completeness, Asher had 27 balls, 13 called strikes, 10 swinging strikes, the 14 foul balls, and 10 balls put into play.

Again, I wouldn't read too much into this one game. My overall take is that it was (obviously) a good outing, but hardly a dominant one. Based on this performance, I would be surprised if he had a dominant start on Saturday; but otherwise he could range from fairly effective to utterly ineffective. Which doesn't say much.

What Is Up With Buck Showalter's Usage Of Hyun Soo Kim?

Up to this point, Hyun Soo Kim has had a very strange season-plus with the Orioles. To summarize, the Orioles wanted him! They signed him last year, after all, for two years and $7 million. Then, Kim performed poorly during spring training and Buck Showalter et al. seemed to sour on him. The Orioles reportedly "talked internally about potentially trying to" get out of his contract, and when that didn't happen, they tried to convince him to accept an assignment to Triple-A Norfolk.

That didn't happen, either, so Kim made the opening day roster, was booed by fans, and sat the bench. He barely played in April and early May, but started to play in late May as he kept producing. The Orioles didn't have better options, and he forced their hand. An average defender at best, his skills are with the bat, and he posted an impressive 119 wRC+ with an on-base percentage of .382 that was the best on the team. I've written a couple other posts about Kim detailing his accomplishments. Jon also wrote a post last October that examined Kim's KBO splits and posited that he should get more of a chance in a full-time role.

Let's just get right to it: Why are the Orioles not looking to play Kim more? They do not have very many on-base weapons, and they need to get better in that department. Last year, the Orioles ranked ninth in the American League with a .317 OBP. Against right-handed pitching, who Kim almost exclusively played against, the O's were tied for sixth (322). Kim doesn't get all the credit for that -- it's well-worn territory that the Orioles were much better against right-handed pitching last season -- but his 129 wRC+ vs. right-handers was second on the team only to Mark Trumbo (146). So far this season, the O's are second worst in the AL in OBP; Kim has the 10th most plate appearances on the team.

Showalter views Kim as a platoon bat, period. That sounds fine, even if it disregards the possibility that he could still get on base at an effective enough clip against same-handed throwers. How low is the bar here? Craig Gentry is getting leadoff at-bats!

But, three things. First, Kim isn't in the lineup against every right-handed starter (he is not in the lineup tonight against Steven Wright, who's a knuckleballer, but he still throws that pitch with his right hand). Second, Showalter frequently removes Kim from games around the sixth or seventh inning for defensive purposes, especially when the Orioles have the lead. That occasionally robs Kim of a plate appearance per start. And third, despite working his way to the second spot of the lineup last year and excelling in that role, Kim has been slotted seventh in the batting order so far this year despite his on-base prowess.

Part of the issue why Kim doesn't play more is roster construction. The Orioles re-signed Trumbo, and he's almost always going to receive his at-bats at DH. That is pushing someone like Trey Mancini to be an inexperienced outfielder, and he's trying to learn on the job. It would also help Kim if Showalter trusted him more in the field, but that just doesn't seem to be an option at this point.

It's early in the season. Players get hurt, and things can change quickly. But it does seem clear that Showalter, or Duquette, or some front office members didn't really want Kim around in the first place and won't give him a chance in an expanded role.

What exactly is going on? If the Orioles were planning to use him this way, why didn't they try harder to trade him during the offseason to at least get something in return? Kim is not a star, but he's useful, and this seems like a poor use of resources.

Aggressive Minor League Assignment for DJ Stewart Makes Sense

DJ Stewart at Florida State (photo credit: Thomson20192)
Aggressively promoting a player through a team’s minor league system is not necessarily a good thing or a bad thing. Sometimes it works out and sometimes it doesn’t. Every player is different, and the success of aggressively promoting a prospect depends on whether or not an individual player is physically and emotionally ready for that next challenge, as well as the front office/coaching staff being able to recognize it. The Orioles have promoted some of their prospects pretty aggressively in recent years, with varying degrees of success, and the organization has been more aggressive than usual in 2017.

While aggressive minor league assignments can be questionable at times, I think it makes sense for D.J. Stewart. Stewart was the Orioles first round draft pick in 2015 (#25 overall), as someone who the organization felt had an advanced hit tool that could move him quickly through the system. And while Stewart has already played at several minor league levels (he started his season in AA), the results haven’t been what were likely expected from him.

The one thing that Stewart has consistently shown is that he does a really good job controlling the strike zone. His walk rates throughout his minor league career (shown above) are a good indication of that. However, as a strong college batter transitioning from the SEC to single A, a walk rate in the 10-16% range is something you’d probably be more likely to expect than be surprised at. Additionally, with not unreasonable strikeout rates, Stewart appears to be making enough contact.

The problem is Stewart’s apparent quality of contact. Full disclosure: I have never seen DJ Stewart play in person. Stewart’s approach and walk rate allow his OBP to stay in the range of “acceptable” to “good”, despite his low batting averages. However, based on the limited minor league numbers available, Stewart’s low batting average does not appear to be luck driven. While his BABIP was low in 2015, it doesn’t appear so low as to account for his overall batting line. Furthermore, it’s entirely possible that his line in Frederick was propped up by the increased BABIP during his time there.

And this leads us to the real issue, which is the lack of power that Stewart has shown during his brief professional career, which is surprising for a player who had ISO’s that ranged between 0.196 and .276 during his 3 years at Florida State. For a player who is currently playing in left field and may have to move further down the defensive spectrum to first base (ESPN’s Keith Law believes that’s where he’ll end up), he’ll need to put up more power than he has shown to date in order to become a productive major leaguer.

Scouting the stat line alone is not generally advised, and as I’ve stated, I have not seen Stewart play in person yet. However, I do think it’s worth noting that publicly available scouting reports generally echo what we have seen in the stats. Despite being a first round draft choice, Stewart is not considered anywhere close to being a top prospect at the moment. Law had Stewart 12th in the organization and MLB has him 24th, while Baseball Prospectus and Baseball America also left him out of their organizational top ten lists. And in a system as light as Baltimore’s, that’s not encouraging. The common consensus seems to be that Stewart’s bat won’t be strong enough to carry his limited defensive profile.

Having said all that, the decision to start Stewart in Bowie is an interesting (and on the surface, a confusing) one. But this may be an acknowledgement that 2017 is an not only an important season for the young outfielder, but for the major league team as well. Pushing Stewart in order to get a better idea of what they have in him as a player is a good move by the organization in my opinion.

The big league team currently finds themselves in a quickly closing window of contention, and the farm system does not offer the type of talent that can help to the MLB team. Promoting Stewart to AA is a gamble that the organization should be taking. If he handles the jump to AA well (reminder that the jump to AA is a big one), then he becomes incredibly valuable to the organization no matter what they view his future defensive position to be. If they think he will eventually be limited to 1B, he becomes a valuable trade piece this summer that the organization didn’t have to begin the season. And considering he’s blocked at 1B by arguably 3 players already on the major league roster, they can afford to deal him. If they think he can stay in LF, then a successful season allows the team to look for a short-term solution in LF next offseason (Hyun Soo Kim is a free agent after this year), with the thought that Stewart could take over as the starting left fielder sometime during the 2018 or 2019 season.

The Orioles don’t really have time to wait for DJ Stewart to develop at his own pace, so the aggressive assignment to AA makes sense considering their current window of contention. If he succeeds, he becomes trade bait or a possible starter in left field during the next season or two, depending on how he’s viewed defensively. If he flops, they haven’t really lost much, as Stewart will turn 24 after the 2017 season. And a 24-year-old hitter who can’t hit and is limited defensively isn’t all that attractive, whether he’s playing in Bowie or Frederick. DJ Stewart is essentially “house money”, and the Orioles are going to keep playing until they either get rich or end up back where they started.

Arrivals and Departures: Hope is a Person Named Alec Asher (3/11/17)

Orioles are attempting a shotgun approach
to finding a starting pitcher.
The season is young, but the club has provided a bit of evidence illustrating that Kevin Gausman, in flashes, and Dylan Bundy are both able to be true top of the rotation arms.  The year has also made many yearn for the quick and successful rehabilitation of rotation stalwart Chris Tillman with Wade Miley's improbable five shutout innings and Ubaldo Jimenez looking expectedly awful.  If there is one question mark for the Orioles season, it is that while the club has a rotation and Norfolk depth. that rotation and depth are cringe inducing.

To some extent, this situation is somewhat reflective of the dire straights of the 2012 season where the club opened up with Jake Arrieta, Tommy Hunter, Jason Hammel, Brian Matusz, and Wei Yin Chen as the starting rotation.  Arrieta, like Gausman, was considered ready to break out and achieve what everyone thought he could be (though, admittedly, Gausman is beginning this season with considerably more accomplished than Arrieta then).  Matusz, like Bundy, was a big question mark with a history of extraordinary praise.  Hammel, a Tillman type with less luster, was acquired from the Rockies for Jeremy Guthrie and was considered a stabilizing force.  Hunter and Chen were wishes and dreams (though I was a major Wei Yin Chen fan).

That season rolled into a major operation in damage control.  Arrieta, Hunter, and Matusz all washed out of the rotation with Hammel being shut down with injury.  The club frantically tried to find pieces to give the team some chance until it could hand things over to the bullpen.  The experienced left us with memories, some persistently scrubbed clean from our collective memory, of Dana Eveland (Dan Duquette had acquired Eveland in a trade and suggested he found some wondrous new pitch, which was kindly exaggerated), Zach Britton (who needed more than his old two seamer as a starting pitcher), Steve Johnson (who was Steve Johnson), Randy Wolf (who was no longer Randy Wolf), Miguel Gonzalez, Chris Tillman, and a resurrected Joe Saunders.  Strangely, having lived through it, I imagined that list to be about ten names longer.

Anyway, the carousel found incredibly useful pieces like Gonzalez and Tillman in the system as well as Saunders coming over cheaply with a salary exchange.  Let us assume that Tillman comes back in May and pitches something like he used to.  That would be big.  Beyond him, the club has the periodically respectable Ubaldo Jimenez and the frequently terrible Wade Miley.  Jimenez, being in his last year, is a short spell of wretched away from being released.  Miley may have some life as a southpaw bullpen arm if things fall apart, but I figure he has to be consistently awful to be jettisoned.  That might restrict opportunity for others down in Norfolk, but we full we expect opportunity to arise with Tillman's delay and a probable implosion by one pitcher or another.

Using a historical based projection model, we can throw some probabilities out there just to get a frame of reference about where each pitcher stands.  For Jimenez, the model is most excited about him by giving him a 5% chance of being a two slot pitcher.  No one else in this group has that in their expected range of possibilities.  It also thinks that there is a 55% chance that he is a bust. The field from which to choose from includes bullpen arm Tyler Wilson and minor leaguers Mike Wright, Jayson Aquino, Alec Asher, Richard Bleier, Logan Verrett, Gabriel Ynoa, and newly signed Edwin Jackson (who somehow is only 33 years old).  How does the model like them?
 
Bust
Usable
3 Slot
Tyler Wilson 70% 30% 0
Mike Wright 75% 25% 0
Jayson Aquino 75% 25% 0
Alec Asher 45% 55% 15%
Richard Bleier 85% 15% 0
Logan Verrett 85% 15% 0
Gabriel Ynoa 85% 15% 0
Edwin Jackson 75% 25% 0

*post print edit - Chris Lee is in the rotation in Norfolk, for now, the model sees him as a 95% SP bust.

For the most part, the numbers above are not all that exceptional.  For a bunch of retreads, we should expect a potential of about 1 in 4 chance that they could deliver some backend arm production.  Nothing too grand, but also much more likely to fail.  The hope is that the innings racked up in Norfolk can provide useful information as to which of these arms may actually pay out.  Duquette's drive to acquire pitchers with options may be very useful to keep a deep and fresh pen as well as maybe getting one more hitter on the bench, but could also provide a sandbox to see which of these arms were overlooked.

One name that surprisingly explodes off the page is Alec Asher.  He is a pitcher that is well known to scouts and well ignored.  The basic book on him is average.  He has average command.  Asher heavily uses his sinker to induce groundballs, but AAA hitters hit those groundballs very hard.  He has no offering that misses any bats.  That certainly is what his career looks like.

Ages 23 and earlier, he appears as a pitcher who performs well  in his league, but looks troublesome as a big leaguer.  Strikeout rate collapsed each year and hit rate slowly increased with walk rate staying normal.  That is the general go of it, but a pitcher with a 3.1 walk rate and a 5.0 strikeout rate in the majors is quite less than desirable.  However, something strange happened last year.  Across levels and into the winter leagues, Asher simply dropped his hit rate by more than 20%.  When batters hit him, they hit him hard. Though, those batted balls found more and more gloves.

How?  Asher dedicated himself to his sinker last year.  MLB performance does not show it with a 38% ground ball rate, but he put up a 52% across all levels and in his winter league.  That is what the bet is on and what the model likes about Asher.  If somehow Asher can generate a 6 k/9 and a 2 bb/9 while delivering a 50% ground ball rate, then this is a pitcher who can fill out the backend of a rotation and, perhaps, even break out as a mid rotation arm. 

However, it seems unlikely.  Whatever Asher did in the minors, the only thing that appeared at the Major League level was a decrease in hits.  Major League hitters were able to avoid the groundballs and they did not miss the ball.  The ball simply turned into outs.  In Philadelphia, Asher had a .231 opponent BABIP, which would have led the league last year among qualified starting pitchers.  That knowledge in and of itself would suggest that there should be a major regression in store for him.  That would have been fifth best in baseball.

Maybe there is something there.  I do not believe it, but he is someone to look at to determine whether he might well be a pitcher that scouts miss.  The model likes him  though and the model, for some reason, thinks the hit rate will remain low.  To some extent, this was about how the model saw Miguel Gonzalez when he signed.  It brings the question whether this will be a rotation best experienced with strong faith or one where you set your expectations low enough to concern your parents.
