Where he does damage, and where to pitch him
Does the most damage down over the middle (+1.7 vs. league per 100; 0.8 standard errors on 45 pitches, inside the noise for the best of nine cells).
Weakest middle-in (−5.4; 2.3 standard errors below average on 38 pitches). Pitchers should attack here.
Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 707 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 | −1 | −1 | −0.4 | −1.4 | 203 |
Runs = range plus his arm and double-play runs spread over his positions by outs (Fielding Run Value, from 2023): what the rating counts.
| Season | Zone | Balls | Outs 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.
