Does the most damage down and away (+1.3 vs. league per 100; 0.6 standard errors on 47 pitches, inside the noise for the best of nine cells).

Weakest down over the middle (−5.4; 2.3 standard errors below average on 49 pitches). Pitchers should attack here.

Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 784 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).
