Does the most damage down over the middle (+3.8 vs. league per 100; 2.0 standard errors on 146 pitches, inside the noise for the best of nine cells).

Weakest middle-middle (−1.2), but only 0.6 standard errors from average on 173 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 2,258 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).

Too few balls in his zone.

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.
