Does the most damage down over the middle (+5.2 vs. league per 100; 2.6 standard errors on 128 pitches, inside the noise for the best of nine cells).
Weakest up and in (−3.1), but only 1.4 standard errors from average on 65 pitches: no in-zone spot to attack yet.
Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 2,185 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 |
|---|---|---|---|---|---|---|
| 2026 | 1B | +2 | +2 | +1.8 | +3.8 | 5,168 |
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 2026, the biggest loss came toward 1B line (−3 outs): a coaching target.
Tools (percentile; arm among 1Bs)| Season | Zone | Balls | Outs vs. exp. |
|---|---|---|---|
| 2026 | 1B | 349 | +1.4 |
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.
