Two More Minor-League Free Agents



In my previous article, I explored four 2015 Norfolk Tides re-signed by the Orioles as minor league free agents. Interestingly, the Orioles signed a few other minor league free agents who have previously played in their organization. Two of these signees are more interesting than usual - one, a former top Orioles prospect, the other someone who might be the best candidate for promotion if the Orioles need an infielder. I'll provide an overview of these two players returning to the Orioles, so that if you see their names you'll have reasonable expectations. Again, while there may be some basic statistical analysis on these players, most of the comments will be based on my observations while I was datacasting games for MiLB.com or scoring games for Baseball Info Solutions. In 2011, 2012, 2013, and 2014 I worked 44, 44, 43, and 45 games respectively.

In August 2013, the Orioles traded Xavier Avery to the Mariners for Michael Morse. Avery had been a once-hot prospect who wasn't developing as quickly as hoped, and the Orioles decided to cut bait. Since then, Avery has played for the Mariners, Tigers, Giants, and Twins AAA affiliates. He played much better for those teams than he did as a Norfolk Tide; in fact, over the past two seasons, Avery has performed in AAA about as well as Dexter Fowler has in the majors:

Avery (AAA): .279/.343/.396
Fowler (MLB): .262/..357/.406

When Avery was with Norfolk in 2012-2013, I was impressed with his athletic ability but not very impressed with his baseball skills. He ran well and stole a few bases, but didn't have an offensive approach that took advantage of his speed. He didn't play center field. He drew walks at a marginal rate. He didn't have a lot of power. The past two years, he's clearly been better.

That said, I am in no way suggesting that Avery would be an adequate alternative to Dexter Fowler. He's the AAA equivalent of Dexter Fowler, a fairly good offensive player who can play a bad center field. Avery's offense will suffer in Norfolk's Harbor Park, and he may have a reputation as a failed prospect.. But if he plays well, and the Orioles need an outfielder, he might get promoted; and it's not impossible that he'll do well.

Steve Tolleson, infielder

Steve Tolleson spent 2012 in the Orioles' organization, playing 29 games for the Orioles and 50 for the Norfolk Tides. With Norfolk, he played mostly at shortstop, although he's played as much second and third in his minor league career. Tolleson spent 2013 with the White Sox AAA affiliate in Charlotte. The past two seasons he's been in the Blue Jays' organization, spending most of 2014 in the major leagues and most of 2015 injured.

Tolleson is a player who doesn't have any really outstanding skill. He hits for a decent batting average and draws a few walks, but he doesn't have much power nor outstanding speed. Defensively, Tolleson doesn't have the range or positioning skill to be a plus shortstop; he doesn't have the position-specific skills to be a plus second baseman; he doesn't have the arm or reflexes to be a plus third baseman.

That said, I think Tolleson is the best current option for a major-league promotion if an injury strikes one of the Orioles' projected infielders. Comparing Tolleson to Paul Janish, Janish is a better defensive shortstop but - possibly because he's such a good defensive shortstop - he hasn't played much at other positions. Tolleson isn't a good hitter, but Janish is a true offensive zero. If Tolleson is healthy, I'd expect him to see at least a little time in the major leagues.

First-Base Defense - A Look at Triple-A

During a rain delay, the Norfolk Tides' media relations intern, myself, and the Tides' official scorer, killed time by discussing the divide between the traditional evaluation methods and the new sabermetric methods. While all three appreciated the goals and efforts of the new analysts, I said that I was concerned that the advanced methods provide the illusion of knowledge without a strong foundation. Many of these statistics are proprietary - the data on which they are based are not available for examination. None of these statistics are verifiable - with offensive statistics, we can confirm that they "work" at a team level, but we can't check these statistics at a team level. And the statistics are inconsistent - it's common for a player to be rated an outstanding defender by one measure and a below-average defender by another.

In order for the newer methods to achieve true recognition, we should first focus on solid, easily understandable counts than on all-encompassing, single-number ratings. For example, before we can determine which of the various advanced defensive metrics is best ,we need to know some basic information that we don't really have - such as how many batted balls defensive players actually field and turn into outs.
During the discussion I referenced above, we all agreed that first-base defense is not measured well by traditional statistics. First basemen are credited with a putout on every play on which the batter-runner is retired at first base, although their contribution to the play is often simply catching a throw from another player. Those plays likely tell us relatively little about a first baseman's defense, because there is (presumably) relatively little difference among first basemen in their ability to catch such routine throws. I said that, before I can appreciate the value of the advanced evaluations, I want to know some fundamental information about first basemen - specifically, the number of batted balls first fielded by the first baseman and turned into outs. This article will look at the first basemen's defense in 2013 games played in Norfolk's Harbor Park.

There are four types of batted balls which first basemen turn into outs - ground balls (taken to the base himself, flipped to the pitcher covering, or thrown to another base to retire a runner); fair pop flies; foul pop flies, and line drives. The table below provides the totals of each type of batted balls that first basemen turned into outs in the Norfolk games for which I have data. First, the totals for both the Tides and their opponents:

Before I looked closely at the play-by-play results I didn't know this. The first thing that struck me is there probably isn't much of a difference between the Norfolk first basemen and the visiting first basemen in their defense at Harbor Park. The one possibly noteworthy distinction is that the visitors recorded substantially more outs on fair fly balls than the Tides, but given the closeness everywhere else that's probably a random variation, not reflecting a real ability. The second thing that struck me is how few outs are recorded by first basemen by catching batted balls in the air. The Tides first basemen caught a fly or line drive about once every 2.6 games; the visitors, about once every 1.86 games. In contrast, first basemen fielded a ground ball that was turned into an out about once every game.

However, it does seem likely that the typical first baseman in Harbor Park fields about 1.1 ground balls a game (or about 160 in a 144-game AAA season) and catches about 0.2 foul fly balls a game (about 30 in a AAA season.) So we're not talking about a lot of plays.

The data above aggregates bad defensive first basemen and good defensive first basemen. It's certainly possible that good defensive first basemen are significantly better, and bad defensive first basemen significantly worse, than the total. Next we'll look at the individual Tides first basemen, to see if there's a significant difference among them.

Four Tides players played what I consider to be a significant number of first-base innings at Harbor Park The first table shows the total number of plays by each player, the second shows the plays per nine defensive innings:

The other first basemen included Chris RobinsonBrandon WoodSteve Clevenger, and Dan Johnson, none of whom played more than five games at first base.

So, in a full 144-game season, Alex Liddi would have fielded about 132 ground balls and Russ Canzler about 177. Britton and Ishikawa would have fit between these totals.

It's interesting that Travis Ishikawa, who has had a good-glove reputation at first base, ranked below the average in the number of ground balls he fielded and turned into outs. The fly-ball data is too small to really allow us to draw meaningful conclusions. One point that may be worth further exploration is that Travis Ishikawa, who had been trained as a first baseman since his amateur days, caught fewer foul fly balls than did Russ Canzler, Alex Liddi, and Buck Britton, all of whom moved to first base from other infield positions.

This is a first step toward providing a better understanding of first-base defense. The biggest conclusion is that more research is needed. To me, the most interesting results are (1) how few fly balls and line drives are caught by the first baseman; and (2) that first basemen, on average, field one ground ball each game.

Of course, there are plenty of complicating factors - the ground-ball and strikeout tendencies of the pitching staff, the number of left-handed and right-handed batters in the opposing lineups, the size of foul territory, etc. The advanced fielding metrics attempt to account for all these factors. However, I don't think we can evaluate the metrics until we see how they compare with the more elementary components of first-base defense. This is a first attempt to quantify these elementary components.
