Where he does damage, and where to pitch him
Does the most damage up and away (+2.0 vs. league per 100; 0.8 standard errors on 40 pitches, inside the noise for the best of nine cells).
Weakest up and in (−2.4), but only 1.0 standard errors from average on 48 pitches: no in-zone spot to attack yet.
Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,026 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).
