BORAS Blowout 2018/19: Pitcher-palooza

As noted before, the BORAS model does not look at relievers, so starting pitching is the final post of the BORAS model blowout this offseason.  Other positions we have covered are:

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

As a reminder, the BORAS model looks at contracts signed from 2013/14-2017/18 in relationship to performance and biological metrics.  Basically, how good were they in the years leading up to the contract, what type of player is he, and how old is he.  Over the years, the model in whole has finished as the most accurate or second most accurate every single year for players who signed multi-year deals above 8 MM per year.  Below those markets and the certainty in the projections decreases significantly.

Below are included several player who have player or team options.  Chris Sale will not be let out of his contract, so there goes a big name.  The same with Carrasco.  David Price will not see in the market what his current contract hands him, so he will stay.  An intriguing name below is Clayton Kershaw.  He has two years and 65 MM left to him on his current deal, but can opt out.  BORAS comes up with his market value as 4/88, which sounds like maybe he should not opt out.  BORAS worries about the missed time Kershaw has experienced over the past few years and his age.

BORAS Blowout 2018/19: Right Field

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

Just chopping some wood, clearing out the BORAS modeling projections.  Here is right field:
Years Total (MM)
Jose Bautista Invite
Melky Cabrera 1 7.7
Lonnie Chisenhall 3 31.5
Curtis Granderson 1 11
Carlos Gomez 1 8.1
Carlos Gonzalez 2 14.5
Brandon Guyer 1 7.3
Bryce Harper 7 138.6
Jason Heyward 2 22.4
Matt Joyce 1 11
Nick Markakis 2 17.6
Andrew McCutchen 3 45.6
Hunter Pence Invite
Yasmany Tomas 4 46.4
BORAS model really thinks Bryce Harper will get a fairly underwhelming deal in comparison to the murmurings of a 400 MM contract for the past few years.  Some thought the 10/250 Manny projection felt light and, well, a Harper deal of seven years just shy of a 20 MM annual value will result in some tsk-tsking.  Regardless, while he has shown glimmers of brilliance, he also seems to have some shortcomings that undermine that value.

A second interesting note is that BORAS thinks Adam Jones is more valuable than Nick Markakis.  I think a lot of folks will disagree with that.  I ran an unscientific twitter poll a while back and four to one think Markakis will see a better pay day.

My last thought is on Yasmany Tomas, who will not opt out of his deal.  That said, 4/46.4 would not be happening for him.

BORAS Blowout 2018/19: Centerfield

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

The BORAS model projections for centerfield are a bit more interesting than the other recent ones.  One, it takes a look at what Adam Jones can expect.  Two, I decided to take a gander at two player who are not free agents: Mike Trout and non-centerfielder Mookie Betts.

Mike Trout 12 407
Mookie Betts 12 417
Lets talk Adam Jones first.  Last year, I made some favorable assumptions and pegged Jones as looking forward to a 2/22 extension.  I cannot find the series of tweets, but someone tagged him on the projection and he voiced his displeasure at the number.  2018 was not exactly kind to Jones in a few ways, including his performance in the field.  BORAS downgraded him to a 2/18.7 deal.  I have a hard time seeing him accept anything below an annual 10 MM salary, but the market may well dry up.

What is going for him that BORAS does not consider is that he is a good clubhouse presence and he is considered able to play all outfield positions even though his effort or comfort looked very subpar in right field as his season ended.  Jones could find himself a second wind.  He has the bat speed and the other qualities that made him an all star quality player.  Perhaps moving to a corner position will help him.  Maybe focusing on a more contact oriented approach to improve his barrelling.  I do not know.  The only negative is that he has sure slowed down a bit over the years.  His speed never played well on the basepaths, but he was a plus runner.  He now is a 45/50 runner, but maybe that was impacted by overuse and injury.

So...I also looked at Mike Trout and Mookie Betts.  The reason why was because I wondered about Manny Machado's 10/250 projection.  I had thought that perhaps the model, lacking data in the young superstar area, might underproject the Machado deal.  The Trout and Betts projections indicate otherwise.  The 400+ MM deals for Trout and Betts appear to validate the model and suggest that we should expect a monster deal for Machado, but far less than was expected a few years ago.

BORAS Blowout 2018/19: Left Field

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

And after a little respite, here we go with the next batch.  The BORAS model projections for left field:
Years Total (MM)
Gregor Blanco Invite
Michael Brantley 4 55.2
Melky Cabrera 1 7.7

Carlos Gonzalez 2 14.5
Marwin Gonzalez 1 11
Brandon Guyer 1 7.3
Jon Jay 1 8
Cameron Maybin 1 9
Gerardo Parra 1 5
This group includes a number of players who have been addressed before.  I think the main miss here, as it has all along, is Marwin Gonzalez.  He is so flexible and useful that I imagine he finds himself a larger deal.  He is a poor man's Ben Zobrist or a rich man's Steve Pearce.

As always, once the model sinks below the 10 MM mark, things can get weird.  No, Gentry will not find himself a 1/7.6 MM deal.

BORAS Blowout 2018/19: Third Base

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

Alright, after being leveled by some respiratory disease for a week, we are back on with the third base installment of the BORAS model.  Some long time readers of the site still think that I call up Scott Boras and get his take, but no.  I have already mentioned it a few times in this series and have gone through some messy bits in years past, but the BORAS model stands for Ballplayer Observation-based Renumeration Assumption System.  The name is a very stretched out attempted to make it BORAS.  So there you go.  Again, I look at the historical relationship between several different performance variables for years prior to signing a contract and the contract itself.  The current model is now a collection of really six models that are split by position and age.  I hope this clears things up.  Go back to the older introduction articles to get more of a history.

The third base batch below contains projections for those who retired as well as a few who have been covered in previous positions.
Years Total (MM)
Adrian Beltre 1 9.7
Asdrubal Cabrera 3 30.9
Josh Donaldson 3 54
Logan Forsythe 1 7.6
David Freese 2 20.6
Marwin Gonzalez 1 13.4
Chase Headley 1 7.4
Jung-ho Kang 2 17.4
Jed Lowrie 4 56.8

Mike Moustakas 2 28.6
Eduardo Nunez 1 6.6
Jose Reyes Invite
Andrew Romine 1 5.3
Pabl0 Sandoval 1 6.5
Luis Valbuena Invite
David Freese looks a little bizarre, but he is one of those guys who when skillfully deployed really helps to boost an offense.  For instance, he only netted himself about 300 PA for the Pirates and Dodgers this season, yet he was able to have a 2.1 bWAR.  That kind of quality usually comes with some investment in years and total money from a club.  However, Freese is considered a platoon bat against left handers, which usually limits the market.  Plus, he may now be more of a first baseman than a third baseman, which also limits the market.  A 1/6 or 1.7 deal would be my expectation instead of a 2/20.6.

Some might think Josh Donaldson's 3/54 deal is a bit light.  From 2013-2016, Donaldson was a golden god with an average bWAR of 6.6.  However, 2017 and 2018 were mired with injuries.  That said, he has had a very late season boost since becoming an Indian and could see a team take a chance.  If you completely ignore last season and have him repeat a modest 4 WAR season, then BORAS would change the expectation to 5/115.  Third base, however, is a fairly bountiful position right now in the Majors, but I could see a club tossing out a 4/100 deal to him.

I think the Headley, Kang, Sandoval, and Romine deals are overly kind.  They exist in this little bubble of the model where they it has a hard time discerning whether a player is really worth a contract and it feels fine putting down a 6 or 7 or 8 MM cost to it.  I think all of these guys are more or less invite quality players.

Anyway, this is the third base group.  Come Monday I will be posting left fielders.

BORAS Blowout 2018/19: Shortstops

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

As I have marched through the model projections, today was one that quite a few folks had circled with some anticipation.  I mentioned the projection on twitter, but here it is in its full glory. Shortstops (aka Manny Machado and some other guys).
Years Total (MM)
Elvis Andrus p58 1 10.5
Asdrubal Cabrera 3 30.9
Alcides Escobar Invite
Eduardo Escobar 1 15.4
Freddy Galvis 2 14
Marwin Gonzalez 1 11

Jose Iglesias 2 22.6
Manny Machado 10 250
Jordy Mercer 2 13
Eduardo Nunez p5 1 6.6
Jose Reyes Invite
Eric Sogard 1 5.9
Machado's value of 10/250 is an astoundingly large contract.  With whispers of a 400 MM deal being considered by the Depot just a year and a half ago, the total value might feel lean.  It is good to remember though that 2017 was a rough offensive year for Manny and this year was a fairly unspectacular defensive one with a shift to Shortstop.  With that in mind, it makes sense that the model is not saying that Machado should be handed a deal that results in the air being sucked out of the industry.

But is the model unable to value machado properly because he is an exceptional talent?  Well, lets consider that by looking at two exceptional players: Mike Trout and Mookie Betts.  I think we can all agree that these guys are stunningly good baseball players.  What does BORAS think about them?
Mike Trout 12/407
Mookie Betts 12/417
That seems to sink that argument for Machado.  Again, one of the murmurs that has followed Machado for years has been when will he go from being one of the 20 best players in baseball to one of the all time greats.  He simply has not gotten there, but he seems to have that potential.  Will a club pay him like an all time great or will they pay him like a current great?

Once you get past Manny Machado, the shortstop position opens up to Asdrubal Cabrera, Eduardo Escobar, and Jose Iglesias.  Cabrera has put in a few good seasons and looks to benefit from those.  Escobar has rebounded nicely from his 2016 season and will probably squeaked out a three or four year deal around 10 MM per instead of the BORAS estimate of 1/15.4 (but who knows?).  Iglesias is fully converting his glove into money, which may or may not pan out.

All in all, looks like a decent set of projections.

BORAS Blowout 2018/19: Second Base

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

So far, we have looked at catchers and first basemen.  Today is second base.  Again, the BORAS model looks at historical performance and regresses it against contract values.  It is a multivariable, multistep approach.  We have been running the models for several years and they are one of the best projection tools for contract terms for regular players.  Things tend to drop off the table for role players or extreme platoon players.
Years Total (MM)
Asdrubal Cabrera 3 30.9
Daniel Descalso 2 18.8
Brian Dozier 2 28.4
Logan Forsythe 1 7.6
Marwin Gonzalez 1 11
Josh Harrison 2 18
Ian Kinsler 1 8.9
DJ LeMahieu 4 47.2
Jed Lowrie 4 56.4
Daniel Murphy 2 34.4
Eduardo Nunez 1 6.6
Jose Reyes Invite
Sean Rodriguez 1 6.5
Eric Sogard 1 5.9
Neil Walker 2 18.2
For fun, I also ran former Orioles Jonathan Schoop through the model.  He is currently under contract with the Brewers and has one more arbitration year left if the Brewers wish to hold onto him.  BORAS thinks holding onto Schoop a bit of a wash and probably worth it.  If Schoop was a free agent, BORAS pegs him as a 5/52.5 player.  This past year undercut his projection by about 30 MM.

Overall, the numbers suggested here are not all that surprising.  Jed Lowrie would be signing through his age 38 year, but he has shown decent versatility and a good bat.  He is not exactly in the same class as when Ben Zobrist signed with the Cubs, but he is not far off.  My guess is that he gets three years and an option.

Daniel Murphy sees his years dwindle due to his acceptable, but not great year this past season.  The model still thinks he can garner something around 17 MM, which would surprise me.  However, he really is not all that far away from his offensive years.  Neil Walker is often thrown in the same bucket as Murphy, but Walker has taken more of a progressive nose dive.  The model can forgive a one year drop, but it finds trends harder to ignore.

Shortstops are next.

BORAS Blowout 2018/19: First Base

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

Yesterday, I wrote about catchers and a bit about the new BORAS model system this year.  Today, we move on to first basemen.  While catchers had a potentially big name in Yasmani Grandal, the big name here (Justin Smoak) has a club option for eight million, which seems like an easy decision for the Blue Jays to pick up as Smoak has accounted for quite a bit of offense these past few years in Toronto.

Here is the BORAS projection for first base.
Years Total (MM)
Matt Adams 1 11.1
Lucas Duda 2 18.2
Marwin Gonzalez 1 11
Joe Mauer 1 10
Logan Morrison m8 2 22.6
Steve Pearce 2 21.8
Hanley Ramirez 1 7.2
Mark Reynolds 1 8.5
Justin Smoak c8 3 44.1
Danny Valencia 1 7
Chris Davis Invite
Mark Trumbo 1 8.3
As this is an Orioles site, I added two players who are not free agents, Chris Davis and Mark Trumbo. Neither live up to their current deals, but Davis is the hard one to take for Orioles fans.  BORAS is so unimpressed with Davis that the invite status is an incredibly kind designation.  For Trumbo, there is an upside there.  He notoriously underperforms as a designated hitter, but if he had put up his on field batting numbers while at first base then he would be looking at something more in the neighborhood of 3/40 or even more.

All in all, the numbers above look about right with a few issues.  BORAS does not know that Valencia is a weakside platoon bat, that will drop his value in the open market (not to mention the mumbling of clubhouse concerns).  Reynolds and Ramirez also feel a bit high as they are uneven veterans with younger talent undermining their value.

BORAS loves it some Steve Pearce.  It always has and it really has always been correct about his value, if not his contract terms.  Teams seem to be concerned about his injuries, streaky bat, and positional concerns, but he always seems to do well as a strong role player.  His arm may not be what it was, but he should be a highly sought after bench/role bat.

BORAS seems a little confused by Marwin Gonzalez and his 1/11 deal seems a little rough.  I see Gonzalez as a healthier Steve Pearce.  These are the kind of guys teams really need.  Their bat can be surprisingly good and they positional flexibility enables a team to use the best player available in the minors when an injury arises instead of the best available player at a given position.  My best is that teams are willing to hand over a greater commitment to Gonzalez.

All in all, I think the projections are roughly about where they should be given that this system does well with 2+ year commitments and AAVs over 8 MM.

BORAS Blowout 2018/19: Intro and Catchers

For the past several Octobers (give or take an extended playoff appearance), the writers here at Camden Depot would put together organizational blueprints for the off season to suggest what the Orioles should do to improve the squad.  That will not happen this year.  However, a major component of that work was our contract projection model: BORAS.

Catcher | 1B | 2B | SS | 3B | LF | CF | RF | DH | SP

In case you forgot or never knew, BORAS takes into consideration several characteristics of a player (e.g., age, offensive performance, defensive performance, historical contract comparisons) and uses that information to project what the new contract will look like.  Each year, we add on another season of data and try to tinker with the model to improve upon it.  This year, the primary model improvement comes from using a batch age model to weight things differently.

Our first series of posts will consider BORAS(po), the position player contract model.  What we found was that younger players and older players were really being valued differently beyond their age.  For instance, our analysis suggests that older players are sought after for their offense with considerably less value placed on their defense.  If we look at encapsulated metrics, defense was valued about half as much on a per run basis as offense was in the 31 and older player set.  For 30 year olds and younger, the value gap shrank from 52% to 17%.  Differences like these can really impact the quality of a model.  By taking these into consideration, we improved the performance of our model internally by about 15%.

In the past, I would just drop the whole player list and then run away.  This year, we will try to be more comprehensive and cover a large swath of the player market as well as putting in some arbitration eligible Orioles because...eh, why not?  Again the caveats remain as they have in the past.  This model does not know about injuries or suspensions.  This model is based on a data set that largely ignores players who get bench level playing time.  Those can be two major blindspots at times.  Finally, our first post here deals with catchers and this model has always struggled with catchers.  In my opinion, this will probably be the worst performing projection group.

Matt Wieters 1 4.1
Caleb Joseph 1 3.9
The adjustments made this year have resulted in a much more competent model at first look, but there are a couple peculiar projections.  I have a hard time seeing Suzuki making 2/20 even though he has experienced a bit of a late career bloom.  Second, I think the model might be a bit too hard on Wilson Ramos who has had to deal with some misfortune with respect to his health.  I also think Ramos gets dinged a bit due to his poor base running, which I think in general does not impact catchers all that much when it comes to signing a contract.

As this is an Orioles blog, I added arbitration eligible Caleb Joseph.  He should be looking at 1.5 to 2 MM in arbitration while BORAS projects Joseph to be worth slightly more in the open market.  With the Orioles organization in possession of a few decent catchers that would come in under the 1.5 MM mark, it may well make sense to non-tender Joseph even though his arbitration value might be a slight bargain.

Tomorrow, I will post first basemen.

Andrew Cashner is Pretty Pretty Pretty OK

At the Depot, we have a model called BORAS.  BORAS is a model that takes away all our experty opinions and troublesome feelings in order to gauge past performance and age, converting that into a contract.  When BORAS considered Andrew Cashner, it determined he was worth a 3/34 deal.  Peripherals indicate a strong role player in 2015 and 2017 as well as quite good performance on the field in 2017.  His velocity is a concern, it has been dropping.  His strikeout rate collapsed, which is troubling.  His avoidance of home runs last year appeared magical.  In other words, he is a pitcher who carries some red flags despite a passable track record.

What the Orioles signed Cashner to was a 2/16 deal with a 1/10 option which requires 360 IP in 2018 and 2019 total to activate.  If he hits all of his incentives then the deal will push up to 41 MM.  For all intent and purposes, this deal looks good for the Orioles if we assume BORAS is right.  BORAS has performed fairly well so far this year as it does every year, but this peculiar logjam of late might mean we are about to see a lot of contract coming in that are low in years and low in guaranteed pay.

What I mean to say is this, the Orioles signing Andrew Cashner is either terrible or good.  If the club sees itself as a playoff contender and Cashner as its third rotation piece, then we are in terrible territory.  If it sees him as the fifth option in a rotation, then it is pretty good.  Fourth, is, I guess, OK depending on who winds up being that third slot pitcher.

This off season, I have told folks to keep their powder dry and wait until you see the whites of their eyes.  With the Cashner signing, I think we are nearing the point to be concerned.  We are not there yet, we are closer.  We need to wait a little bit longer.  This could still work out.  Or not.  It all depends on what the actual role of Cashner is.  He can be a good pitcher and is perhaps a better candidate to be a good pitcher than someone like Miguel Gonzalez who went for slightly less.

There is still some hope if the next guy through the door is Lance Lynn or Alex Cobb.  If it is Tillman, then, you know, yeah.

Adam Jones: So What Would An Extension Look Like?

Recently, Adam Jones reminded the Orioles fan base of something.
This left me with the question about what exactly would an Adam Jones deal look like and whether it would even be a good idea.  People age and all good things come to an end, but Jones still looks like a capable player.  Last year, in the second half of the season, Jones slashed 307/343/502.  That was some prime time Adam Jones action.

To try to look at the angles, I employed the newer version of BORAS to see what his 2019 contract would look like.  I also used a comp model to project his 2019-2023 seasons (ages 33-37).  With the often leaked front office perspective that Jones is a true RF now, I also modeled out what happens when a center fielder moves to right field.  Finally, I assumed that the 2018 season had already played and Jones performed on par with what ZiPS projects him to do.

BORAS 2.0
As you know, the BORAS model looks at a players recent past and compares it with recent contracts to determine how many years a player will sign for as well as what yearly salary the player will take on.  For Jones' 2018 season, we will assume his ZiPS projection is accurate and go from there.  BORAS suggests his age 33 and 34 season would be covered in a 2/23 deal if he is a free agent a year from now.

Given Jones' recent contract and how a two year extension is really not all that much of an extension, I would advise him to not sign that deal if I was his agent.  It would be a shock if he was not able to secure one year deal for each of those off seasons, so I would suggest him to bet on himself and go bigger.  But, what does BORAS think the benefit or cost is to wing it on a one year basis?


Yeah, that is an ugly, bare-bones graph.  The horizontal axis is what Jones might do in 2018 using WAR as an encapsulating statistic for what goes into the model.  The left is AAV and the right is years.  Jones probably needs something north of a "3 WAR" season to get more than two years.

Comp model
We have used comp models before.  Basically what we try to do here is take a player's most recent performance and find similar players who play similar positions.  When we did this for some players, like Manny Machado, it was effectively impossible to find enough players at that age who offensively performed similarly.  For Jones, it is a bit easier, but he is such a unique centerfielder that we needed to consider corner outfielders in the methodology to have a large enough sample size.

Who is in Jones' age 33-37 comp model?
Al Martin, Rondell White, George Bell, Jose Guillen, Mike Morse, Eric Byrnes, Jacque Jones, Cody Ross, Glenallen Hill, and Nelson Cruz.

Admittedly, it is a weird group.  Nelson Cruz and Rondell White do not look like twins, but the process looking at the entire population has delivered good comps in the past.  What we find in this group (Cruz' age 37 year is projected) is that only Cruz makes it to the end.  Most of the players end their career before the midway point of their age 35 season.  To account for those lost seasons, we project their performance, but it identifies uncertainty in the population as we travel further down the path of age.

Moving From CF to RF
A second consideration that needs to be made is that based on the leaks coming out of the warehouse (it might well be the only leak) is that the club no longer views Jones as a competent centerfielder, seeing him true defensive position as a rightfielder.  The old rule of thumb was that moving from center to a corner outfield position was worth an increase of about five runs in defensive ability, which covers about half of the -10 run positional adjustment from center field to right field.

Trying to be more exact or at least more defined, I decided to run a series of regression models for arm, error, and range values.  However, none of the models came out as significant.  All hovered around the 0.1 value.  If those were useful, it would suggest that Jones, a -4 run ZIPS value in center, would translate over to a +2 run rightfielder largely on the strength of increase range performance.

I then decided to do a batch model by looking at fielders from 2015-2017 who played at least 200 innings in right field and left field in a single season.  I then batched these by Statcast sprint speed in three groups: greater than 28.5 ft/s, 27.5-28.5 ft/s, and less than 27.5. Jones would fall into the final center fielder speed category as his 27.2 mark was one of the slowest in MLB last year for that position.

Anyway, what I found is that the fast group actually sees a reduction in range value of -5 runs.  This likely has to do with reduced opportunity in right field.  If you have stellar speed and can use it to expand your range, then a tight foul territory reduces that usefulness.  That reduction though is slightly reduced from improved throwing and error prevention, which results in an overall loss of -2 runs for that speedy group when converting over to right field.

The mid-level speed and lowest speed groups both appear to benefit similarly overall.  The mid-level group sees slightly more improvement in range and slightly less improvement in arm than the slowest group.  However, they both come in around a 5 run improvement.  This would suggest that sliding Jones over to right field would make him a +1 run right fielder.  Part of me wonders if this might be an underadjustment because Jones has shown in the past that he is far batter at moving toward left field than he is at moving toward right field.  Add in that route running and you could imagine him being a +5 run, but for this exercise, we will assume he performs like the population performed and that he is a +1 RF.

All Together Now
Incorporating the conversion into the comp model, what we get below is the projection for Adam Jones' next five years assuming he logs 550 PA each year.


Proj 550 PA AVG OBP SLG xWAR
2019 .254 .304 .418 1.4
2020 .251 .303 .426 1.5
2021 .251 .305 .433 1.6
2022 .235 .289 .401 0.6
2023 .228 .28 .397 0.3

What it suggests is that players like Jones maintain a level of performance through their age 35 seasons and then collapse.  Of course, that collapse is largely due to the projection given to all the players whose careers ended mid age 35 season or before.

If we assume that Jones is more like the players within the group who had longer careers, then we would wind up with this projection.

Proj 550 PA AVG OBP SLG xWAR
2019 .281 .335 .476 3.1
2020 .272 .326 .472 2.8
2021 .269 .323 .479 2.8
2022 .250 .307 .443 1.8
2023 .232 .286 .414 0.7

Well, we still see that major drop off even when the population has more players who were able to go deeper into their careers.  That age 36 season (2022) looks like a considerable wall.

Conclusion and Comparisons
The comp model thinks Jones is worth about 2/20 or 3/32.  BORAS 2.0 thinks the extension should be 2/23.  For BORAS to think that Jones should get a three year deal, he would need to give a 3 WAR kind of season and then would be looking at a 3/41 deal.  All of that is in the neighborhood of market value and expected performance value.

For the Orioles, the issue is a bit more complicated.  The signings of Chris Davis and Mark Trumbo along with the plethora of corner outfielders in the minors makes Jones, although a franchise important figure, not exactly occupying a position of need in the future.  In terms of a team player, he still is one of the more important players in the clubhouse, so you could fathom extending him and dealing out of the club's strength or finding a new home for someone like Mark Trumbo to push Trey Mancini into a more natural position at DH and sliding Austin Hays to left field.

Could that be done?  Can you wipe Trumbo's salary off the books?  Does Jones give you a better shot of winning instead of relying on players like D.J. Stewart and Ryan Mountcastle coming through in the near term?  Does Jones relieve pressure on a hitter like Mountcastle and lets him mature a bit longer before being called up?

In the end, I could see Jones being handed a 3/36 extension and it turning out OK.  An athletic and relatively healthy player his entire career, he probably is more alike the players in the top end of the comp model.  He certainly is not a Nelson Cruz (few are), but you can see a number of attributes that will like age well and a 1.5 player over his age 33-35 season is a useful player and looks better than previous comp models on guys like Denard Span.

BORAS (po) 2.0: Improving Upon the Original BORAS Position Player Contract Model

A few years back, I introduced two models to predict contracts terms: BORAS (pi) and BORAS (po).  That acronym, like many in the data science world, came first and then the words later, but it means Baseball Observation-based Renumeration Assumption System.  The idea being that the bias in determining contract value (even in comp model systems) could be removed, perhaps, by throwing all the recent contracts together in a big pot and regression modeling them with certain performance parameters.

The BORAS (pi) system, which is for pitcher contract, worked remarkably well.  The cumulation r2 of the model is 0.86 and the median miss is 1.7 MM.  Some of the misses are great, such as being off on Ian Kennedy by 11 MM AAV.  Simply put, highly encapsulated pitching metrics were rather effectively in projecting what a contract would be for pitchers.  Traditional metrics were batched together and more "advanced" metrics were batched together.  The previous three years of performance were considered.  It worked out.

I used the same approach with the BORAS (po) system for position players.  Encapsulation of traditional and those more "advanced" metrics appeared to be the wrong move.  Where the pitching metrics for starting pitchers largely all met needed confidence points, the data for position players was more varied.  For instance, fielding metrics for position players needs about two to three years to really stabilize and I was batching this information into more certain offensive data.  In other words (and this is very simply stating it), I was valuing a great fielding season the same as a great offensive season which is a no good, terrible, oh so awful way to do things.  It yielded an r2 of 0.47 and median value off of 3.9 MM, which is decent if you know nothing.  However, a passing interest in contract terms would make you far more away of probable terms than this model would.

This performance has led me to think about other ways to utilize data and come up with, perhaps, a better performing model.  First, I wanted to thin down data sources and noted that, unlike the pitching model, the hitting model valued similar statistics regardless of their traditional nature or more "advanced" nature, so I decided to just go ahead and use less encapsulated "advanced" metrics and ignore the traditional ones.  I also separated out fielding metrics and put them in a more appropriate bin with similar certainty.  So, now we have BORAS 2.0 (po).

Below is how the models compare.

BORAS 2.0 appears to do better with the higher end players.  Justin Upton at 5/100.8 made more sense than 5/83.9.  Cain makes more sense as a 4/64.7 than 5/92.2 player.  However, BORAS 1.0 seems to be more into handing our NRIs.  It will be interesting to see how this offseason plays out and whether BORAS 2.0 is an actually improvement on the original model.
