Sabermetric Research looks at the defensive debate swirling around Justin Verlander and Rick Porcello. Phil Birnbaum uses a Monte Carlo approach to show how luck could result in Verlander getting better than Tigers average defense on the days he pitched, and uses a run support analogy.
All well and good, except pitchers have little to do with run support in the AL, and they have quite a lot to do with defense. What I want to see, and haven’t so far, are how difficult or easy balls in play were against Porcello and Verlander compared to other pitchers on the team. So if the expected BABIP against Verlander was .240, then his .255 number doesn’t look so good. Somebody has those numbers.
