Does the most damage middle-in (+7.8 vs. league per 100; 3.7 standard errors above average on 94 pitches).

Weakest up and away (−0.5), but only 0.2 standard errors from average on 79 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 2,125 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).
