As a follow-up to the introduction of BatCode, here’s its estranged twin PitchCode. In this post I’ll share two ways to use PitchCode for John Lester’s 2009 season. The first works just like BatCode – showing the results of each at-bat (against Lester) with a line representing a walk or hit and line thickness representing power. The second approach zooms out to the inning level and shows each of Lester’s 2009 innings, with line thickness representing the number of runs Lester allowed in each inning.
Which one (if any) do you like? What do they reveal (if anything) about Lester’s 2009 season?
