Does the most damage up and in (+4.8 vs. league per 100; 2.1 standard errors on 36 pitches, inside the noise for the best of nine cells).

Weakest down over the middle (−3.7), but only 1.6 standard errors from average on 65 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 947 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).

The zone rating counts every ball hit to his part of the field while he played there, his club’s positioning included; Savant OAA uses his actual starting spot and is the better individual grade. They agree best in the outfield. See the model card.
