Ryan Webb was one last week’s more surprising non-tenders. Miami decided Webb wasn’t worth his projected $1.5 million salary, according to Matt Swartz’s arbitration projections. In the past two seasons, Webb was worth 1.2 wins for the Marlins while working in 131 games. But don’t feel bad for Webb. He didn’t stay unemployed long: Baltimore added the reliever on a two-year deal for $4.5 million.

The team reportedly liked how Webb’s ground-ball skills compared to the freshly-traded Jim Johnson, and acknowledged Webb’s career splits while also noting he made improvements in that department this past season. Pitchers can change the type of pitcher they are, such as Edward Mujica’s transition from an extreme fly-ball pitcher to a heavy ground-ball pitcher. But how does a pitcher  improve his ability to get out opposite-handed batters without adding a pitch?

In line with our Fabulous Split Week here at FanGraphs, this post will utilize the framework for estimating hitter platoon skill outlined on Monday. If you crave more details, read that post, or, even better, take a look at the sections from The Book on which it is based. Today, I’ll apply this analysis to four of the remaining DH-ish players left on the free agent market. This will allow us to set aside issues of defense and get a simple overview at how platoon skill effects the value of some hitters. Recalling Monday’s post, platoon skills are regressed to the mean (here based on league-wide splits 2007-2009), moreso for righties (regressed against 2200 PA) than for lefties (1000 PA).* For the projected overall wOBA, I use CHONE’s projections as listed on the FanGraphs player pages.

* David Appelman informs me that the “career splits” pages only include stats starting in 2002. That’s helpful in this case because we’re getting the more recent data for older players, although platoon skills usually don’t change much over most players’ careers. But keep in mind that the “career” numbers listed below are post-2002.

Let’s begin with some lefties:

Russell Branyan
Career Split: 15.2% (437 PA v LHP)
Regressed: 10.6%
CHONE projected wOBA: .359
Estimated wOBA vs. RHP: .367
Estimated wOBA vs. LHP: .329

Like most saber-nerds, I love talking about Russell Branyan. Although he has a platoon-guy rep, in 2009, when he got more PAs against LHP than ever before in his major-league career, he hit well against them (.345 wOBA). It’s still a small sample, but it does show that sometimes regression to the mean happens right before our eyes. Branyan actually projects as about league average vs. LHP. His back is problematic and he probably went into the off-season with unrealistic expectations about what he could get in free agency, but it’s hard to believe he won’t find a starting job before Opening Day.

Carlos Delgado
Career Split: 18.2% (1400 PA v LHP)
Regressed: 14.2%
CHONE projected wOBA: .337
Estimated wOBA vs. RHP: .352
Estimated wOBA vs. LHP: .304

In an earlier post on free agent 1B/DHes, I hinted that the once-great Delgado might want to consider hanging it up. But this is a case where a larger split makes a guy more valuable with a decent platoon partner.

Hank Blalock
Career Split: 21.8% (1060 PA v LHP)
Regressed: 15.4%
CHONE projected wOBA: .328
Estimated wOBA vs. RHP: .342
Estimated wOBA vs. LHP: .291

It may seem like Hank Blalock was good just a couple years ago, but it’s really been six. He has even a bigger splits than Delgado, but he’s also not as good of a hitter in general. A .342 wOBA part-time DH can be useful, but not often.

And now some righties…

Jermaine Dye
Career Split: 9.1% (1196 PA v LHP)
Regressed: 7.1%
CHONE projected wOBA: .345
Estimated wOBA vs. RHP: .338
Estimated wOBA vs. LHP: .363

Dye seems to have realized he can’t play the field anymore, which is good. Given how long he’s been in the league relative to Ryan Garko (discussed in Monday’s post), that their estimated split is almost exactly the same points to how much observed RHH platoon splits need to be taken with a grain of salt.

Johny Gomes
Career Split: 15.4% (600 PA v LHP)
Regressed: 8.1%
CHONE projected wOBA: .336
Estimated wOBA vs. RHP: .327
Estimated wOBA vs. LHP: .354

Now this is a righty with a big split, although not as big as people think. Despite Gomes’ reputation, his estimated platoon split isn’t any bigger than the average lefty split. Of course, he’s only about average against RHP.

This small selection reflects what we’d generally expect — lefties have larger splits that vary more widely. This implies that when setting up a platoon, given similar defensive skills (or lack thereof), the key is finding a lefty with a big split, and to find a RHH who is a decent overall hitter. And, of course, there’s the issue of whether bringing in a platoon partner is worth the roster spot. For example, given that the expected performance of Gomes and Dye (the lesser half of the platon) vs. LHP isn’t that much better than Branyan’s overall projection. On the other hand, on the right team, Gomes or Dye + Delgado might make sense.

There has been speculation recently that, should the Rockies continue to struggle, they may be looking to part ways with offensive juggernaut Matt Holliday. Holliday, a Scott Boras client, will be a free agent following the 2009 season and will likely enter the market looking for a long-term, big-money contract that either a)the Rockies cannot give or b)the Rockies won’t want to give. Instead of focusing on the fiscal aspects of this situation, though, I wanted to take a look at his home and road splits; last year it became somewhat common knowledge on the East Coast, when discussing Holliday vs. Jimmy Rollins, that much of Matt’s stats came from his home park.

Here are Holliday’s yearly splits, from 2004 until now:

2004 H: .338/.406/.603, 10 HR, 29 K, 229 PA
2004 R: .240/.287/.367, 4 HR, 57 K, 210 PA

2005 H: .357/.409/.593, 12 HR, 45 K, 264 PA
2005 R: .256/.313/.416, 7 HR, 34 K, 262 PA

2006 H: .373/.440/.692, 22 HR, 44 K, 334 PA
2006 R: .280/.333/.485, 12 HR, 66 K, 353 PA

2007 H: .376/.435/.722, 25 HR, 58 K, 363 PA
2007 R: .301/.374/.485, 11 HR, 68 K, 350 PA

2008 H: .356/.440/.671, 4 HR, 13 K, 84 PA
2008 R: .283/.371/.402, 2 HR, 13 K, 105 PA

In case you hadn’t noticed, he has done leagues better at home than on the road. Put together, here are his career splits:

Home: .363/.426/.662, 73 HR, 189 K, 1274 PA
Road: .274/.336/.444, 36 HR, 238 K, 1260 PA

Finding comparisons generally helps to further a message so I probed the BR Play Index for players with career numbers similar to those in each of his splits. I found just one person from 2004-now with overall numbers anywhere near his home production: Albert Pujols.

In looking at his road numbers a plethora of names appeared but the closest match was the .275/.339/.456 line in this 4+ year span of Aubrey Huff.

While there is little doubt Holliday could have won the MVP award last season and little doubt about his talent, prospective teams looking to acquire his services and ink him to a mega-bucks deal might want to take into consideration he has been Albert Pujols at Coors Field and Aubrey Huff everywhere else. Not to say Huff is a bad player, which is the common misconception when looking at drastic statistical differences such as this, but he is not on the same level as Pujols.

Perhaps Holliday likes being at home, in general, regardless of whether said home field is Coors Field, but I would tend to think he is someone that truly benefits from that park.
