Does the most damage middle-away (+4.1 vs. league per 100; 2.1 standard errors on 130 pitches, inside the noise for the best of nine cells).

Weakest middle-in (−3.5), but only 1.8 standard errors from average on 131 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 2,200 pitches · faded cells are within one standard error of average. A spot is called only when it is farther from average than the best or worst of nine average cells gets 95% of the time (set from the league’s own pitches: about 3 standard errors above, 2 below).
