IMPORTANT BLOG ANNOUNCEMENT

PLEASE CHANGE YOUR BOOKMARKS AND FEEDS TO THE NEW URL, YANKEEANALYSTS.COM. TYU IS IN NO WAY AFFILIATED WITH THE NEW YORK YANKEES OR YANKEES UNIVERSE.

Recently I was thinking about fielding data, something that’s admittedly an unperfected area of sabermetrics. Debate over just how imperfect the data is has been raging for some time now. I think most of us know that UZR and the likes have serious flaws- prone to sample size issues the data can skew analysis in a variety of ways when used improperly. That being said, it’s currently the best we have. I think it can all be used as long as we keep in perspective the myriad problems with the data- I think of it as a legitimate asterisk when looking through fielding data.

So with all that being said I got curious and wanted to look at the Yankees defensive data that’s available. As you’ll see, I ran into some problems though that I think should be addressed. So keeping in mind that this is a pretty imperfect study and just conversation fodder, away we go.

Did you know the Yankees have had the worst fielders in baseball since 1980? For the past 30 years the Yankees have had some pretty poor defenders. This probably isn’t surprising to fans who remember the days of Hideki Matsui, Bernie Williams and Gary Sheffield patrolling the outfield (we’ll see how horrifying this was shortly).

Of course it didn’t always used to be like this. If you look at all defenders from 1920 to 2010, 90 years of baseball, the Yankees rank 3rd out of 30 teams in fielding runs above average. From 1950 to 2010 they were 8th. Then they really fall off a cliff. Looking at just players from 1970 to 2010 the Yankees rank 26th in defensive runs above average. Finally from 1977 to 2010 the Yankees ranked dead last in defensive runs above average. Obviously the fact that the Marlins, Rays, Diamondbacks and Rockies haven’t been around for very long skew those rankings.

I put together a quick leader board from Fangraphs to look at the worst Yankee defenders over their careers in pinstripes since 1920. I added wRC+ just to make everyone feel a bit better about this. Check it out:

NAME wRC+ Fielding
Bernie Williams 125 -152.5
Derek Jeter 125 -113.4
Hideki Matsui 124 -73.7
Dave Winfield 134 -60
Mickey Mantle 171 -44
Gary Sheffield 136 -41.2
Robinson Cano 116 -36.8
Alfonso Soriano 118 -36.2
Bobby Murcer 129 -35
Sammy Byrd 110 -34
Paul O’Neill 125 -31
Chuck Knoblauch 108 -31
Reggie Jackson 148 -30
Bobby Abreu 125 -28.3
Jim Leyritz 109 -26
Dion James 115 -23
Jorge Posada 125 -22.3
Jason Giambi 145 -20.2
Mel Hall 102 -20
Danny Tartabull 127 -19
Mike Pagliarulo 96 -19
Mark Koenig 87 -19
Alex Rodriguez 151 -17.6
Tim Raines 121 -17
Ken Griffey 110 -16
Matt Nokes 99 -16
Felipe Alou 101 -15
Tony Womack 55 -14

What can you really say about Derek Jeter and his defense that hasn’t already been said? E tu, Bernie? Just think back to 2004 folks when Bernie, Matsui and Sheffield were all in the same outfield. That’s mind numbing, isn’t it? Seeing so many familiar names from the past 20 years or so really explains why those defensive rankings plummeted the more the data was thinned out, no? Poor Mickey. What was he doing at 1st base? Those knees would have really benefited from some DH time.

After looking at this for awhile, I realized there was a problem. This list is from Fangraphs which uses UZR from 2002 on. Before that, it uses Sean Smith’s TZ data for the WAR components. So is it really fair to consider this list that mixes the two data sets? Not really. Using TZ alone looking at Jeter’s career for instance, he’s 129 runs below average. Both systems agree that Jeter has been really, really bad. On the other hand, Bernie Williams 2002-2006 TZ has him as a -70 fielder which is still awful. However when you switch the 2002-2006 data with UZR, which is what these leader boards do, it gets even worse- UZR rates him as -110 for 5 SEASONS. So Bernies total career fielding total looks this way:

TZ alone:                                - 118

TZ plus UZR after 2002: -152.5

That’s 35.5 runs difference.

So after bouncing around with this stuff what’s my conclusion? I think it would be a whole lot more fair if these WAR numbers found on fangraphs would stick to one fielding system or another. The numbers you see on fangraphs historical WAR charts use BOTH fielding systems: TZ for anything before 2002 and UZR for anything after. If you played before 2002 and after, your Fangraphs defensive WAR component uses both systems. That just seems inconsistent, no? Why not use TZ for any player whose career began before 2002?

I love WAR and the data that Fangraphs provides. I think we should always use the best available methods to help evaluate the game. For me, Fangraphs is the place to go for baseball statistics. I hope that someone can shed some more light on this issue though because its one I don’t really understand.

Mike Axisa at River Ave Blues wrote a great post yesterday about one of Cashman’s comments at his talk with Josh Norris:

Josh Norris sat down for a chat with Brian Cashman on Friday (part onepart two), getting the GM to spill the beans about a number of topics, including Jesus Montero, the draft, and a bunch of other stuff. Unfortunately he didn’t say anything controversial, so those of you who enjoy that sort of stuff are out of luck. Rather than give you just a link and telling you to check it out, I wanted to talk briefly about some of the stuff Cashman discussed. I block-quoted some of it and added my two cents below, but still, you should go check out the interview in its entirety. Josh did a great job as usual. On to the quotes…

We have been very aggressive in the draft and re-dedicated ourselves to tools, not necessarily to performance coming out of the amateur ranks.

I’m going to focus on the tools over performance part, because the Yankees have drafted quite a few guys with questionable college performances and turned them into quality prospects because they focused on the talent. David Phelps jumps to mind, he had a 4.65 ERA and a decidedly unsexy 7.26 K/9 in his final year at Notre Dame, but his minor league career features a 2.50 ERA (382.1 IP) and last year he struck out eight men per nine. David Adams hit just .286/.384/.411 in his draft year at Virginia, but as a pro he owns a .281/.370/.439 batting line with wood bats against much better competition. Andrew Brackman belongs in this conversation as well.

This caught my eye as I began my annual ritual of rereading Moneyball before spring training. The performance vs. tools thing has been a hot button issue since Moneyball came out. Moneyball was a book about a lot of bigger ideas than tools vs. performance, but that dynamic is one of the more controversial points made by the book. For those that haven’t read it (I highly recommend you go buy it today), Billy Beane was angry that his scouting department wasn’t producing results. They generally picked players based upon traditional measures of tools – their swing, their batting practice power, their arm, their speed, etc, or the speed of their fastball. So, with Michael Lewis taking notes, Beane decided to spend the 2002 draft selecting players almost entirely by their college statistics. Although he selected some very useful players like Joe Blanton, Nick Swisher, Brad Ziegler, and Jonathan Papelbon (did not sign), the strategy is generally considered a failure. Scouts were correctly able to identify that Jeremy Brown was too fat to catch in the major leagues.

No one, including the Oakland A’s, drafts today using the Moneyball strategy. Teams tried it for awhile, but it didn’t work. However, when Cashman says that they are going back to tools, he isn’t suggesting that they are going back to pre-Moneyball methods of player evaluation. That is because the true lesson of Moneyball was that both the scouts and Billy Beane were wrong. Billy Beane was wrong that college baseball statistics can predict the performance of a professional baseball player. It turns out that scouts are actually pretty good at predicting how tools will translate to performance. However, the scouts were wrong about what kind of baseball players help a team to win games. They didn’t care if a player took walks, made pitchers work or controlled the strike zone. They overvalued defense (though we’re moving back a little bit that way), baserunning, the ability to hit for singles, and certain other characteristics.

This is really important for a number of reasons. I’m sure that the Houston Astros have a bunch of very experienced, capable scouts out there. They can tell the Bryce Harpers apart from the Jeremy Browns, and would probably have prevented the A’s from drafting Ben Fritz. However, I’m not convinced that the Astros management gets the very basic concepts of what makes a baseball player good. Fret all you want about the merits of stats like VORP and WAR, but the basic concepts behind them are undeniable: players should be compared against their positional peers in some systematic way, getting on base is the most important thing for hitters, players don’t have much control over balls in play, etc. The A’s scouts didn’t get this, and I’m willing to bet that a few teams in the MLB still don’t either.

Why have the Yankees succeeded in the late and middle rounds the draft lately? I’m sure that they have some great scouts, but Damon Oppenheimer isn’t personally going in and checking out every 12th round pick. But they’re still churning out potential major leaguers at a fantastic rate, along with quite a few high-end prospects. They correctly realized that David Adams sophomore year at UVA (.372/.454/.522) was more representative than his very disappointing junior year (.286/.384/.411), which turned off a lot of major league teams who regarded him as a 2nd round pick. Ditto for David Phelps, who had a disappointing junior year following a really great sophomore year. The difference is less about tools vs. performance than it is about correctly interpreting performance. Having scouts analyze tools is a huge part of this, but it all plays into the big picture.

The real lesson of Moneyball was that a lot of very smart people in baseball misunderstood the basic physics of the game. I get the sense that the Yankees have both a very good understanding of the basic physics of the game and a feel for the art of finding players who can succeed under those physics. Its a blend of Billy Beane and the scouts he derided.

Yours truly committed a sin of omission yesterday and forgot to include Russell Martin in my defense of the Yankee offseason, so here’s my apology to you (and Russell, on the off chance he’s reading this). Signing Russell Martin was a good move for the Yankees. He’ll be making just $4MM, which is affordable for the Yankees. He also has a year of team control left, so if the Yankees like what they get out of him in 2011, they can tender him a contract and keep him around for 2012.

On the field, he gives the Yankees a good defensive catcher and someone who can at least not embarrass himself at the plate. The .307 wOBA and his 86 wRC+ may belie my point a bit, but those numbers are a bit mundane because of a big drop in power–.081 IsoP over the last two years. In that time, though, Martin has had a 12.0% walk rate, leading to a .350 OBP. Essentially, that’s all Martin has to do for his time with the Yankees to be worth it: play good defense and avoid making outs. CAIRO projects Martin to have a .336 wOBA, which would be more than acceptable, considering Martin’s defense.

That’s where I want to take this post. What should we reasonably expect from Martin in 2011? I’m comfortable going with the .336 wOBA projection, though I could have us temper those expectations because his wOBA has been under .310 for the last two years. CAIRO assumes 547 PAs for Martin in 2011, so let’s run a quick WAR projection, assuming a league average wOBA of .327 (2010′s league average) and plus 4.5 defense (average of 2009-2010 DRS), we get a rather lofty 4.0267 WAR projection for Martin. That’s really high, but I think it comes from a few things: the nice positional adjustment (+12.5), good projected defense, and a lot of PAs. Despite this calculation, this is not a fair expectation of Martin.

As noted, he hasn’t hit that well lately and I doubt he gets that much playing time. Why not? Well, we all assume that at one point, Jesus Montero will be (once again) destroying the International League and he’ll be ready to join the big league club. At that point, I think we’ll say goodbye to Francisco Cervelli and we’ll see Mr. Martin shift to the back up catcher’s role. When Montero comes up, there’s no way he’s not going to be playing every day.

If Russell Martin can give the Yankees about half a season of competent play, keeping the seat warm for Jesus Montero, I’ll be happy. If he can do more than that, I’ll be even happier.

For part 2, I’ll look at 2009. The Yanks obviously went on to win the World Series that year, but as with any other season the GM had his share of good and bad moves. Again, I’m only going to look at major moves, ones involving a player that spent time on the 25 man roster. I won’t look at retaining their existing players as free agents since I want to see if the changes he made worked out or not, but I will look at free agents they let walk, such as Bobby Abreu from this year. I’ll do a quick analysis of each move, and assess a grade of net plus or net minus for the franchise which will largely be based on WAR. I’ll total up each at the end of the post, and give a final total at the end of part 5.

2009 New York Yankees Trades and Transactions

October 30, 2008

Bobby Abreu granted Free Agency.

Controversial move at the time for the popular Abreu, but Cashman wanted to get younger and more athletic after 2008. Was replaced with Nick Swisher, who at the time was coming off a horrible year (1.2 WAR) in CHI. After coming off a down year (1.7 WAR) in 2008 for the Yanks, Abreu had a bounce back season in 2009 for the Angels (2.9 WAR) but Yankee fans barely noticed. Swisher posted a 3.3 WAR in 2009, and an even better 4.1 WAR in 2010. All totaled, Abreu has been worth 5.1 wins since leaving while Swisher has been worth 7.4, and Nick appears to be entering his prime years.

Traded Wilson Betemit, Jeff Marquez and Jhonny Nunez to the Chicago White Sox. Received Nick Swisher and Kanekoa Texeira.

One of Brian’s all time best deals, buying low on a good player coming off a bad year in a bad situation with the White Sox and their manager. We just went over how good Swisher has been, so lets look at it from the White Sox perspective. They got one year of  Wilson Betemit at -0.6 WAR. Nunez got a look with the Sox in 2009 and pitched to a 9.53 ERA in 7 games, and followed that up pitching to a 5.48 ERA last year pitching for their Charlotte AAA affiliate. Marquez has posted ERAs of 9.85 (11 games) in 2009 and 4.48 ERA in 2010 in AAA. Kenny Williams pretty much got nothing, except maybe to get his manager to stop complaining about a good player.

December 12, 2008

Signed A.J. Burnett as a free agent.

The ever-enigmatic AJ had a solid season for the Yanks in 2009, posting a 3.4 WAR and pretty much earning his 16.5 mil salary, give or take a mil. But he was awful in 2010, worth just 1.3 WAR and on the days he was off, he didn’t give his team much of a chance to win. The Yanks didn’t feel they had an in house replacement ready to take his place after the Hughes-IPK experience in April and May of 2008. The main FA alternative was Derek Lowe, and given the age on the Yanks left side of the infield and the fact Lowe doesn’t miss many bats, I would have made the same move. But AJ barely earned 1/3 of his 16.5 mil salary last year, and his fastball velocity has been dropping steadily for the past 3 seasons. When you win a WS and go deep into the playoffs the following year, its hard to argue the move was a total negative, but AJ’s contributions didn’t help last year. Net minus, mostly on the fact he hasn’t earned his salary.

Grade-Net Minus

December 20, 2008

Signed CC Sabathia as a free agent.

This one’s a no-brainer. Can you imagine the Yanks without CC? Worth 11.4 WAR and has even outproduced his hefty salary.

Grade-Net Plus

January 6, 2009

Signed Angel Berroa as a free agent.

Depth move with the 2003 Rookie of the Year that didn’t work out. Moves like this are why Brian prefers in house options like Ramiro Pena, who at least won’t complain about playing time.

Grade-Net Minus

January 6, 2009

Signed Mark Teixeira as a free agent.

Replaced the aging, addled Jason Giambi and more than doubled Jason’s 2.5 WAR with a 5.4 WAR in 2009. Had a down year in 2010, but is another no-brainer. Has roughly earned his high salary, give or take a mil.

Grade-Net Plus

February 13, 2009

Signed Brett Tomko as a free agent.

Low risk, back of the bullpen depth option that paid off nicely for the Yanks, pitching to a 0.64 ERA in 10 games. Wanted to be released to get more playing time, the Yanks obliged and was awful for the A’s. Brian just got lucky on the sample size here, but hey, it counts.

Grade-Net Plus

August 7, 2009 (Standings)

Purchased Chad Gaudin from the San Diego Padres.

Pitched nicely for the Yanks, even if his peripherals didn’t look great. Pitching Coach Dave Eiland was said to have tweaked his slider, maybe it was that or just another case of Brian getting lucky on the statistical noise chart. But again, it counts.
