Does the most damage down and in (+3.1 vs. league per 100; 1.3 standard errors on 51 pitches, inside the noise for the best of nine cells).

Weakest down over the middle (−6.0; 2.6 standard errors below average on 58 pitches). Pitchers should attack here.

Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 764 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).

Runs = range plus his arm and double-play runs spread over his positions by outs (Fielding Run Value, from 2023): what the rating counts.

Range by direction (OAA)

No directional data (needs a qualified season at one position).

SeasonZoneBallsOuts vs. exp.
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.
