Spitballing: Blanton in the Phillies’ Rotation February 25, 2011

The Phillies have one of the best rotations, on paper, in baseball today. Although some people are measured in their optimism, including Jayson Stark, I think the important thing to remember is that we’re arguing over whether they’re “the best ever,” not if they’re going to be competitive. Rotations that bring this kind of excitement at the beginning of the year are few and far between. The Mets, for example, aren’t drawing this kind of expectation – guys like R.A. Dickey and Mike Pelfrey are solid, but they don’t have the deserved reputations of Roy Halladay, Roy Oswalt, Cliff Lee, Cole Hamels, and Joe Blanton.

I’m hardly the first to say it, but Joe Blanton seems to be the odd man out. He’ll be making about $8.5 million next year. Blanton faced 765 batters last year, fourth behind Halladay, Hamels, and Kyle Kendrick. Immediately behind Blanton was Jamie Moyer with 460 batters faced. For the record, the fifth-most-active pitcher faced 362 batters in 2009 (Chan Ho Park) and 478 in 2008 (Adam Eaton). Let’s take that number and adjust it to about 550 batters faced, since Blanton will get more starts than most fifth starters and he’ll stay in longer since he’s a proven quantity. In a normal year, the Phils face about 6200 batters, so that means Blanton’s 550 will be about 9% of the team’s total. (That figure is robust even in last year’s Year of the Pitcher with depressed numbers of batters faced.)

According to J.C. Bradbury’s Hot Stove Economics, this yields an average marginal revenue product of 3.15 million. This figure is based on the average rate that pitchers prevent runs and the average revenue of an MLB team. Obviously, Blanton is a better than the average pitcher (ignoring his negative Wins Above Replacement last year) and the Phillies make more money than most teams, but this is a pretty damning figure.

The other thing to take into account is that Blanton’s marginal wins aren’t worth as much to the Phillies now that they have a four-ace rotation. He won’t get every start and he won’t be a 20-game winner. Even if he were, he’ll be providing insurance wins – he might have an extra ten wins over a AAA-level replacement, but chances are that those wins won’t make the difference between making the playoffs and missing them when you figure in the Phillies’ solid bullpen and run production.

Instead, let’s say Blanton goes to the White Sox, just to pick a team. Jake Peavy and Edwin Jackson combined for 765 batters faced, so plug Blanton in for Freddy Garcia with 671 batters faced – a worst-case scenario. That would be 10.85 % of the batters faced, bringing him up to about 3.8 million. In this case, though, you have a team who finished 6 games back and missed the playoffs. If you replace Garcia with Blanton, you stand a very good chance to make the playoffs. That’s another way of saying that the Phillies’ 6-game lead over Atlanta (the NL wild card team) was worth less than the Twins’ 6-game lead over the White Sox (when neither team had as many wins as the AL wild card).

Economists would refer to this as a diminishing marginal returns situation – when you have fewer wins, around the middle of the pack, each additional win is worth a little less. This captures the idea that taking a 110-win team and giving them 111 wins would cost a lot of money and not yield much extra benefit, but a 90-win team making 91 wins might let them overtake another team.

The upshot of all of this? Trade Blanton for prospects. Rely on the bullpen and develop a future starter. Roy Halladay won’t be competitive forever.

Pitchers Hit This Year (or, Two Guys Named Buchholz) December 23, 2010

Okay, I admit it. This post was originally conceived as a way to talk about the supremely weird line put up by Gustavo Chacin, who in his only plate appearance for Houston hit a home run to leave him with the maximum season OPS of 5.0. Unfortunately, Raphy at Baseball Reference beat me to it. Instead, I noticed while I was browsing the NL’s home run log to prepare to run some diagnostics on it that Kenley Jansen had two plate appearances comprising one hit and one walk. (Seriously, is there anything this kid can’t do?)

In Kenley’s case, that’s not entirely surprising, since he was a catcher until this season. His numbers weren’t great, but he was competent. What surprised me was that 75 pitchers since 2000 have finished the season with a perfect batting average. 9 were from this year, including Clay Buchholz and his distant cousing Taylor Buchholz. Evan Meek and Bruce Chen matched Jansen’s two plate appearances without an out. None of the perfect batting average crowd had an extra-base hit except for Chacin.

Since 2000, the most plate appearances by a pitcher to keep the perfect batting average was 4 by Manny Aybar in 2000.

At the other end of the spectrum, this year only three pitchers managed a perfect 1.000 on-base percentage without getting any hits at all. George Sherrill and Matt Reynolds both walked in their only plate appearances; Jack Taschner went them one better by recording a sacrifice hit in a second plate appearance.

Finally, to round things out, this year saw Joe Blanton and Heureusement, ici, c’est le Blog‘s favorite pitcher, Yovani Gallardo, each get hit by two pitches. Gallardo had clearly angered other pitchers by being so much more awesome than they were.
