2010 ZiPS Projections - New York Yankees

Obviously, not a lot goes wrong wrong for teams that win 103 games. The Yankees were no exception, essentially improving offensively at every position from 2008. Even the things that did go wrong, like Joba Chamberlain not being a star this year, weren't exactly deal-breakers.

The Yankees scored the most runs this season (unless the Angels score 37 more runs in their game against the A's, which they're losing 2-1 in the 3rd as I type this) and even though the offense is fairly old, they talent is simply too deep and the position that may need to be fixed soonest, catcher, is the position Montero plays, at least right now. Not that Posada stinks or anything, but backstops pushing 40 aren't exactly known for gentle declines.

The team has a few more questions with the pitching, most notably just what to do with Hughes long-term after his excellent stint in the bullpen and what to make of Wang. It's not a deep free agent pool for starters, so I wouldn't be surprised if the team mostly trolls for relievers after the big Sabathia/Burnett haul last winter.

All figures in % based on projection playing time 


Disclaimer:  ZiPS projections are computer-based projections of performance.  
Performances have not been allocated to predicted playing time in the majors - 
many of the players listed above are unlikely to play in the majors at all in 2009.  
ZiPS is projecting equivalent production - a .240 ZiPS projection may end up 
being .280 in AAA or .300 in AA, for example.  Whether or not a player will play 
is one of many non-statistical factors one has to take into account when predicting 
the future.

Players are listed with their most recent teams unless Dan has made a mistake.  
This is very possible as a lot of minor-league signings are generally unreported in
the offseason.  

ZiPS is projecting based on the AL having a 4.46 ERA and the NL having a 4.41 ERA.

Players that are expected to be out due to injury are still projected.  More information
is always better than less information and a computer isn't what should be projecting
the injury status of, for example, a pitcher with Tommy John surgery.

Positional offense is ranked by RC/27 and divided into quintiles based on what the 
most frequent starting players at each position did in 2007-2009.  Excellent is the top
quintile, Very Good the 2nd quintile and so on.

Yeah, I see Rivera I definitely think Doug Jones.


Doug Jones, Age 40 - 80.1 IP, 2.02 ERA, 231 ERA+.

That line looks pretty much like a standard Rivera season, and there aren't many 40 year old closers to compare against.
   5. He's Bought a Bat Like Prince Fielder  Posted: October 04, 2009 at 06:19 PM (#3340183)
RB, what you're probably seeing is that there aren't exactly a whole bunch of awesome 40-year-old relievers. No doubt ZIPS wouldn't know that Rivera is a much harder thrower, but they were both pitchers that struck out a lot of guys, had excellent control, and one ridiculous go-to pitch (Jones had an amazing change).
   6. RB in NYC (Now with Resolutions!)  Posted: October 04, 2009 at 06:25 PM (#3340185)
I do know the reason Rivera gets compared to Jones, it's just an odd comparison because you don't think of Jones of being in Rivera's class, although he was excellent.
   7. APNY  Posted: October 04, 2009 at 06:51 PM (#3340197)
Romine projects better than AJax.

What's the avg OPS+ for catchers? Romine projecting to 74 already seems very encouraging.
   8. Dan Szymborski  Posted: October 04, 2009 at 06:58 PM (#3340200)
OPS+ for all MLB catchers tends to be between 88 and 92 or so while the OPS+ as a starting catcher tends to be between 92 and 96.
   9. RB in NYC (Now with Resolutions!)  Posted: October 04, 2009 at 07:04 PM (#3340204)
Montero for catcher!
   10. Big Red Basketball (NJ)  Posted: October 04, 2009 at 07:11 PM (#3340211)

   11. The Yankee Clapper  Posted: October 04, 2009 at 07:20 PM (#3340215)
I'd take the over on Jeter on the theory that the 8th most hits for an age-35 season in MLB history constitutes pretty good evidence (along with the rest of his career) that he will age much better than average.
   12. rconn23  Posted: October 04, 2009 at 07:23 PM (#3340216)
Wow. Basically projecting every Yankee player to decline, even those in their 20s.

Can't wait for the Red Sox 2010 DIPS that shows Buchholz with a 1.03 ERA.

What would you expect when 8 of 9 position player starters had a 2009 OPS+ above their career averages?

Can't wait for the Red Sox 2010 DIPS that shows Buchholz with a 1.03 ERA.

An Oriole fan writing a projection system with a pro-Red Sox bias would be a rather odd choice, I imagine.

Dan, I have what I'm sure is going to be shocking news for you. There are a certain number of Yankee fans who have used the last eight years of no title to fuel one of the most intensely wacky persecution complexes in the history of psychiatry.
   15. APNY  Posted: October 04, 2009 at 07:40 PM (#3340226)
No projection system is going to expect Jeter and Posada to be great forever, they're already historical outliers, even if we as fans think we are seeing unique players who can keep it up.
   16. Cowboy Popup  Posted: October 04, 2009 at 08:51 PM (#3340244)
Thanks for posting the Zips Dan.

I think that Jeter projection is pretty good, 114 OPS+ and average defense at SS. That's a very valuable season. Of course I'd love him to hit .330 again but I would take that projection.

I'm surprised about Melancon's awful projection. I know he's struggled in Major League time but his minor league numbers are really good. Are his control issues in the Majors bad enough to make his projection that low or are his minor league numbers not as impressive as I think they are? To some extent my question also applies to Robertson.

I like the rotation depth the Yanks are going to have. Gaudin, Mitre, Wang, Kennedy and MCAllister are all reasonable enough 5th starters and some of them have some pretty high upside for 6th-10th starters.

I hope this year is the beginning of a more consistent stretch for Cano and that in 10 years we look back and wonder what the hell happened to him in 08.

Can't wait for the Red Sox 2010 DIPS that shows Buchholz with a 1.03 ERA.

This is annoying because it's exactly what the posters here expect from Yankee fans and it's just going to lead to more anti-Yankee posts and distract from actually talking about the team.
   17. Dan Szymborski  Posted: October 04, 2009 at 08:55 PM (#3340247)
I'll make sure and double-check Melancon; he does look a bit high.

This one is weird to me:
DuncanShelley RF 10% 23% 22% 25% 20% BrunanskyTom BuhnerJay DyeJermaine
So, Brunansky was giving a run on 105ish OPS+ seasons at age 29, and it's not unreasonable to think Duncan could match that offensively. Bruno was an excellent defensive player, so it's not really the system's fault that comes up. And Dye seems like another not-the-fault-of-the-system glitch, Dye becomes a comp for Duncan because he put up that 38 OPS+ at age 29, when he tried to come back from a broken leg too quickly.

Buhner, though, was a middle of the order threat on a playoff team, and remained such for a couple years. Why does he come up as a comp for a minor league slugger?

Well, if that's all it is, I take back every nasty thing I've ever said about the park, including its financing. But though their .858 / .821 home / road OPS+ split shows that their new Stadium didn't hurt, what does a similar .859 / .753 split for the Red Sox say about the way that Boston hitters use Fenway as a crutch?
   22. Dan Szymborski  Posted: October 04, 2009 at 10:04 PM (#3340286)
Why does he come up as a comp for a minor league slugger?

First, the baseline for Duncan is a little higher - ZiPS/zMLE have Duncan as a 114 OPS+ in a neutral context.

There's also the issues that I calculated exact component park factors (rather than generalized ones) and with a slightly easier league, Buhner's 126 OPS+ over those years in question drops to 120 OPS+ in a neutral context.

Even that 6 is actually one of the bigger differences among the comps - remember, shape matters, too. If I have a 115 OPS+ hulking slugger, I want a group that contains 110 and 120 OPS+ hulking sluggers, not Carl Crawford!

Some more on Duncan's list:

Jason Lane

Part park, part league scoring more than I thought, part everybody but ARod playing better than usual. As noted above, considering that 8 of the 9 regulars played above their career averages, I should have hit low.

   25. Gonfalon Bubble  Posted: October 04, 2009 at 11:12 PM (#3340324)
And C.C. is projected to retire with 290 wins, the highest sub-300 career total since 1887. Cue the strangely unsatisfying "we will never again see another 290-game winner" columns.
   26. Dan Szymborski  Posted: October 04, 2009 at 11:16 PM (#3340329)
Damon is projected to 3000 hits. Interesting.

He's less than 600 hits away at this point and if he just has 2 full seasons of 150 hits, (a weak total for him and he's coming off the best year of his career), he can probably limp the rest of the way as a part-timer if he has to. He's played 140 games for 14 years in a row now, so he's really been able to pile up the hits.

Assuming Biggio gets in, if he makes it to 3000, Damon will probably be the first 3K player not to make the Hall, with the exception of those not in for other reasons (Rose of course and very likely Palmeiro).
   27. cardsfanboy  Posted: October 04, 2009 at 11:25 PM (#3340333)
was it on this board that someone claimed the greatness of Jeter, because he'll likely be one of six players to have 3000 hits and 2000 runs scored? (the qualifiers of 3000 hits knock, Ruth and Bonds of the list from 2000 runs scored?

Assuming Biggio gets in, if he makes it to 3000, Damon will probably be the first 3K player not to make the Hall, with the exception of those not in for other reasons (Rose of course and very likely Palmeiro).
If Damon gets 3000 hits, I think he gets into the hof, he'll be compared to Brock enough and his superior defense (even with the weak arm) will be enough to get him in.

Maybe eventually, but it's a tough crowd now. When Tim Raines gets 1/3 of what he needs for qualification, there ain't going to be many who are going to "feel" like Johnny Damon is a HOFer.

20 years ago, sure. It's pretty scary that it only took some knee problems to keep Buckner from getting 3000 hits. Now that would be comical.

I think he has it harder than Brock did, but he is going to get compared to Brock, no matter whether that is the best comparison, and in almost every aspect in that comparison Damon is going to grade out better.
   30. SG in ATL  Posted: October 04, 2009 at 11:47 PM (#3340349)
FWIW, ZiPS had the highest average projected run total for the Yankees in my Diamond Mind projections at the beginning of the season.

cairo: 855
chone: 847
hbt: 860
marcel: 856
pecota: 822
zips: 883

So don't pick on Szym too much. If anything, pick on PECOTA.
   31. SG in ATL  Posted: October 04, 2009 at 11:50 PM (#3340352)
Dan, I'm assuming if you switch Hughes to a starter, his projection would go up to an ERA of around 4.70? Is that about right?

Will he? It's getting late out here, so I won't take a deep look at the numbers, but Brock retired with the single-season and career records for stolen bases. For "Fame", that counts for a lot.

I'd say Brock is perhaps the one guy who is non-Hall of Meriter, Hall of Famer, with both groups getting it right.

I don't see Damon having much of a chance of making it (absent more seasons like this one), 3,000 hits or not. Of course, I'm perhaps the most disbelieving of automatic markers here.

If Damon ends up with 3000 hits he's also gonna end up with 1800+ runs and that's very select company (e.g. Brock had just 1610). He'd be top 20 all-time in runs, possibly top 20 in hits (Biggio at 3060). Not bad.

I love comparables lists! For Posada we have Piazza and Gabby Hartnett and I'm feeling it, but who in the good christ is Wally Schang? Sounds like a funny fake name to give at Fuddruckers.

Yes, he was - better than his contemporary Ray Schalk, who is in the HOF on the strength of being one of the "Clean Sox" of 1919 (and Warren Brown's pushing).

The Book Blog Thread explaining Regression.
Important reading.


From that link:

The thing that people don’t understand (actually one of the things) about regression toward the mean in baseball is that the reason any above or below average player will always regress, on the average, towards average, is that they were not really as good or bad as we thought in the first place, based on any of their stats. That goes for Sabathia, Halladay, Bonds, Chipper Jones, etc., etc. Chipper Jones is not as good as his career stats tell us, even after you do all the appropriate adjustments. Same for Halladay. And Sabathia. And everyone else who has been above average and we think has true talent X. When I say “as we think” I mean as their stats suggest, not as we think based on a credible projection which already does the regression. And of course, there is some chance that any given player is better than his prior stats - it is just that the chances of him being worse is greater than the chances of him being better. That is ALWAYS the case, as long as we properly define the mean for that player.

That is the KEY to understanding regression toward the mean and is what most people don’t understand, even if they think they understand the concept.


The first highlighted passage is mgl's. The second highlighted passage is one that needs more elaboration. In this case, I'm specifically wondering how those numbers for Phil Hughes were arrived at, numbers which seem to imply a mean that's a lot worse than what his performance this year (his first full injury free year) might project. What assumptions were you making about injuries and managerial schizophrenia when you project him to a 4.32 ERA, with 12 starts in 40 games?

I'm obviously missing something here, but what is it? How do you take the sum of Phil Hughes's minor league and Major League career and come up with a line like that? Seems to me that it has to be based on an expectation of another major injury somewhere along the road.

Jesus, a serious baseball fan who hasn't heard of Wally Schang? He's one of the 20 best catchers of all time, right? Hell of a player, probably the only catcher worth a damn b/w Bresnahan and liveball.

ZiPS assumes that a player's recent usage reflects his future usage. A human can better guess how Hughes will in fact be used.

As for the 4.32 ERA, that reflects ZiPS not knowing about the rib and muscle issues. I found back when I started doing this that removing seasons in which a pitcher spent at least 30 days on the DL made projections significantly less accurate - the injury performance doesn't go away because players with an injury have an increased risk of being injured. So what amounts to a 6.27 ERA in 2008 is part of his record.

That is ALWAYS the case, as long as we properly define the mean for that player.

Ugh. This again. MGL should never write about statistics. Let's break it down:

1. any "player will always regress" WRONG. The notion of "always" is antithetical to statistics.
2. "on the average" CONTRADICTS ANY MEANING OF THE WORD "ALWAYS"
3. "towards average" WRONG
....... really, that first sentence is just horrible.
4. "the chances of him being worse is <sic> greater than the chances of him being better" CONTRADICTS #1 AND #3 which clearly state he has no chance of being better (unless he was below average)
5. "ALWAYS" -- wrong (antithetical) but hard to know what this is referring to given the preceding series of conflicting statements
6. "as long as we properly define the mean for the player" -- AYE, THERE'S THE RUB

We don't know what Chipper Jones' "true" mean is. But if we did know Chipper's "true" mean, he would be every bit as likely to over-perform as under-perform that mean (give or take a bit of skew in the true distribution -- i.e. it's not necessarily normal but it's probably close enough).

As to the rest ... a player whose true mean is a 110 OPS+ but who has hit for a 100 OPS+ the last 3 years will, OF COURSE!! ALWAYS!! CHANCES ARE!!, regress towards his true 110 OPS+ -- i.e. he will regress away from average. The projection systems will, on average, under-predict such a player because the projection systems won't know he's a true 110 OPS+ player. That's not a big deal but it's a fact.

Regression towards the mean is really the wrong concept because we don't know what the mean is for any individual player. In a sense, we don't even predict a mean for the individual player. A better explanation of how projection systems work would be something like the following (admittedly short on specifics):

From 2007-2009, 8 players with at least 1200 PA had an OPS+ of 140 or better. However, from 1901-2009, only 57 hitters have had a 140 OPS+ for their careers (minimum PA of 4000). Even if you limit it to ages 25-32 (at least 3000 PA), you only get 90 hitters. Therefore we assume/estimate that it would be incredibly unlikely that the unknown distribution of true talent levels would produce 8 true 140 OPS+ hitters at one time. Therefore some members of this group must be over-performing their (unknown) true talent so we estimate that, on average, members of this group will regress towards an OPS+ of 100. That is, as a group they averaged something like a 150 OPS+ but we'll project the group to average about a 135-140 OPS+ in 2010. We really haven't a clue what any individual member of that group will do (even Teixeira has a 1% chance of being "poor" next year) and we know that it is highly likely that, if only by chance, one or more of them will hit better in 2010 than they did from 2007-2009.

Of course the projections adjust for other predictive factors (most importantly age) and they don't use OPS+, but that's the gist of it.

Or if you prefer ... regression towards the mean would be the correct concept if every player in baseball had the same mean -- i.e. came from the same population. We are very highly confident however that Albert Pujols is not in the same population as Aaron Miles. So the task becomes figuring out which population a given player most likely belongs to. The main drivers behind our guess are the player's recent performance and age. Unfortunately, even using 3-4 seasons, these are small samples to detect small differences in performance that are so important in baseball. So we have a great deal of uncertainty around a mean estimated purely by recent performance and age.

The question which follows is -- do we think that performance-age mean estimate is an unbiased predictor of the player's true mean? That's not an easy question to answer but history and earlier statistical analysis do quite clearly show that such a mean is biased. It is biased upwards for those who performed above average (in the overall league sense) and biased downward for those below average.

But let's be clear about what's "really" going on. There are a group of players who come from the "true 120 OPS+" population. Over the last few years, a few of these guys (say 20%) had an OPS+ between 90 and 110 -- they will all be projected to about a 100 OPS+. 30% were between 110 and 120 and they'll be projected to about a 110 OPS+ (everybody loses 5 points towards average). 30% were between 120 and 130 and they'll be projected to about a 120 OPS+. And 20% were between 130 and 150 and they'll be projected to about a 130-135 OPS+. You'll notice the projection system has correctly projected only 30% of that population to their true mean.

In the subsequent year, those "true 120" guys who were projected to a 100 will be considered "true 100" flukes after putting up a 120 season and will get projected to about a 105 OPS+ even though, were we omnisicient, we'd have no reason to expect them not to repeat their performance.

This is one thing about projection systems -- they can't identify "true 120" players who have underperformed the last 3-4 years. They see them as guys who have put up a 100ish OPS+ and will remain at a 100ish OPS+. They handle average or better players who overperformed their true means fine (by regressing them towards 100); they handle average or worse players who underperformed their true means fine (by regressing them towards 100). But above-average players who underperformed their true means and below-average players who overperformed are not being projected correctly because they can't be identified.

That's not a fault of the projection systems necessarily. But the key is that they treat the mean estimate (after regression) as "true" rather than incorporating the substantial amount of uncertainty that there is in that projection. Unfortunately, the uncertainty introduced into a projection just from basic randomness of a season's worth of PAs is already huge (again, see Teixeira ... or Swisher who could basically perform at any level) and adding in the uncertainty of our mean estimate only shows how little we do know about individual players. And I don't know what can be done to try to improve that mean estimate other than possibly incorporating some biometric data (e.g. eye tracking ability), maybe psychometric, or things like pitch f/x (and what comes after).

By the way, how many of you knew that Matt Holliday is one of the 8 players in that 140+ group? The full list, in order: Pujols, AROD, Mauer, Teixeira, Berkman, Holliday, Pena, Gonzalez. I would have guessed at least those last 3 would have been in the 130s.

So what amounts to a 6.27 ERA in 2008 is part of his record.


IOW it's an educated guess that derives from a large database of past cases rather than an educated but non-provable belief (based on how he's performed since his recovery) that the injury was of a flukish sort. That's reasonable, and thanks for the explanation, even if I'd still bet on Hughes far outperforming that projection.

Great job Dan, thanks for taking the time.

One thing I noticed, Teixeira shows as projecting to "AV" D at first, but has a 79% chance of being VG or EX according to ODDIBE . . . that doesn't make sense to me . . .

Walt,

You missed Chipper, Hanley, Manny, and perhaps a few others too. But it doesn't change the main point.

I like to refer to the "classic" case of regression to the mean, at least the one I recall most in introductions to the subject, characteristics of offspring. Tall fathers tend to have tall sons (compared to average height), and short fathers tend to have short sons. But tall fathers tend to have sons who are shorter than them, and short fathers have sons who are taller than them.

It is other words, the second random variable (son's height, or year X+1 OPS), conditioned on the first (father's height, or composite of OPS up to year X) will tend to regress part way toward the overall mean.

A couple key things: when projecting, you're conditioning on a random variable, not a known constant. "Tend to" doesn't mean "always." Even if we conditioned on true talent, we'd see some hitters not regressing toward that true talent. And, of course, players get better or worse all the time, so true talent is not constant across time.

Joe, those are the odds for offensive standing.

I have Teixeira's defense as AV/66 at 1B for 2010 (I projected him at +6 runs range-wise in 2009 for a VG and +3 runs in 2010 for an AV)

The 79% EX or VG are his odds to be in the top 40% of starters in offense in 2010.

I think the 79% is the likelihood of his offensive production being among the top 40% of first basemen.

   57. Dan Szymborski  Posted: October 05, 2009 at 03:57 PM (#3340979)
I wouldn't worry about the scariness of individual comp - the listed are simply the top of a big bunch. It's listed mostly because it's interesting and people like seeing the comps.

In fact, everyone's going to have some scary comps simply because bad things happen a lot to great pitchers, good pitchers, average pitchers, and bad pitchers. That ZiPS sees 154 wins left in Sabathia is a pretty good thing!

The top cutoff for the POOR 1B group is roughly an OPS+ of 94.

Pretty much everyone, no matter how good, has some established chance at having a terrible year. A-Rod's 0% there is actually 1-in-243, so it certainly could happen.

2007 really pulls that multi year average up.

herefore we assume/estimate that it would be incredibly unlikely that the unknown distribution of true talent levels would produce 8 true 140 OPS+ hitters at one time. Therefore some members of this group must be over-performing their (unknown) true talent

From 2007-2009, 8 players with at least 1200 PA had an OPS+ of 140 or better.

FWIW BBREf PI says there are 14 playesr with 1200+ PAS, and OPS+ over 140 from 2007-09:
Cnt Player            OPS+   PA  From  To
+----+-----------------+----+-----+----+----+
    
1 Albert Pujols      178  2020 2007 2009 
    2 Alex Rodriguez     158  1837 2007 2009 
    3 Chipper Jones      152  1730 2007 2009 
    4 Prince Fielder     150  2094 2007 2009 
    5 Mark Teixeira      149  1967 2007 2009 
    6 Hanley Ramirez     147  2051 2007 2009 
    7 Manny Ramirez      147  1654 2007 2009 
    8 Joe Mauer          145  1704 2007 2009 
    9 Matt Holliday      144  2006 2007 2009 
   10 Lance Berkman      143  1895 2007 2009 
   11 Carlos Pena        142  1789 2007 2009 
   12 Ryan Braun         141  1863 2007 2009 
   13 Adrian Gonzalez    141  2101 2007 2009 
   14 Miguel Cabrera     140  2043 2007 2009

Of the 14, Pena is alone in that he has just 1 year over 130, that would seem to indicate that 140 is likely not his true talent level.

Hmmm ... I used PI too ... I must have accidentally set a criterion I didn't mean to set.

Anyway, the explanation in #51 is clear and simple. The key point I want to add regarding projection systems is that they are regression towards the mean conditional on past performance (usually a weighted function of the last 3-4 years) plus age and a few other variables. And that's fine -- I don't mean to question their utility as standard sorts of models. The problem comes in when they are interpreted as regression towards the player-specific mean.

Dan's presentation (and PECOTA's and I suppose most of them) are good in that they are displaying at least some of the uncertainty. What I'm not clear about is how that uncertainty is being estimated (feel free to link me if you want Dan).
   63. Dan Szymborski  Posted: October 06, 2009 at 08:21 AM (#3341372)
To put it as simply as possible, ZiPS generates a model for likelihood of improvement or decline of various factors (and how they interrelate), based on how the very large group did, and then Monte Carlos a million seasons of the player.

I treat aging and regression toward the mean separately.

It seems odd to me that Swisher's projection is significantly worse than last year's projection when he just had the best season of his career. Is ZIPS projecting his skills to deteriorate rapidly from his age 29 season on?

He's an old players skills type (low BA, lots of walks, lots of Ks), so maybe ZiPs sees him petering out soon.

Also, this was just another (good) season for him - it's certainly not clearly his best.

That's certainly a possibility and the only reason that I can think of to explain the projection.

Also, this was just another (good) season for him - it's certainly not clearly his best.

His wOBA this year was .375, his next highest was .368 back in 2006. Maybe 'clearly' was too strong, but this is the best offensive season that he's had in his career. His defense was a bit better in 2006, but that shouldn't affect the offensive projections.

I note that his top comp is Dwight Evans, and Evans had his best offensive seasons from 29-32 and was productive for a long time after that. Burroughs, too, had a couple of productive seasons between 29-31, although he fell off much more rapidly than did Evans. It's very possible that Swisher could be very productive over the next year or two and then fall away fairly quickly.
