Does the most damage down and in (+5.4 vs. league per 100; 2.4 standard errors on 42 pitches, inside the noise for the best of nine cells).
Weakest up and in (−1.4), but only 0.6 standard errors from average on 41 pitches: no in-zone spot to attack yet.
Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,049 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).

Fielding
2027 rating at every position he can play · OAA by position · range by direction · tools. Same engine as the Fielding Lab and the Winter Plan.
| Season | Pos | OAA | Range | Arm, DP | Runs | Batters |
|---|---|---|---|---|---|---|
| 2024 | 1B | −3 | −2 | −0.9 | −2.9 | 409 |
| 2023 | 1B | +1 | +1 | −0.7 | +0.3 | 274 |
Runs = range plus his arm and double-play runs spread over his positions by outs (Fielding Run Value, from 2023): what the rating counts.
At 1B in 2024, the biggest loss came toward 3B line (−3 outs): a coaching target, though he plays C in 2027.

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.
