Comparing pitchers to hitters

For all the number wonks out there, SG at RLYW has quite the post, in which he compares hitters to pitchers using wOBA. There’s a conversion process which attempts to keep everyone on the same scale, and to some extent it’s a success. Atop the list are names you’d expect: Zack Greinke, Joe Mauer, Edwin Jackson, Roy Halladay, Victor Martinez. However, when you get further down the list things get a bit dicey. Phil Coke is ranked ahead of Jon Papelbon (as is fellow Sick Justin Masterson). There are a few other things which make the list seem skewed, but it’s an interesting take on comparisons. The best part, by far, is that David Ortiz is ranked below Jose Veras. Also, the bottom two slots belong to, surprise surprise, Chien-Ming Wang and Daisuke Matsuzaka. Wang takes that contest by .003.
