Does the most damage middle-in (+3.6 vs. league per 100; 1.7 standard errors on 90 pitches, inside the noise for the best of nine cells).

Weakest up and in (−0.1), but only 0.1 standard errors from average on 76 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 2,523 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).
