Where he does damage, and where to pitch him
Does the most damage down over the middle (−0.3 vs. league per 100; 0.1 standard errors on 104 pitches, inside the noise for the best of nine cells).
Weakest middle-middle (−2.8), but only 1.5 standard errors from average on 150 pitches: no in-zone spot to attack yet.
Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,950 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 | SS | +19 | +14 | +2.7 | +16.7 | 4,876 |
| 2025 | SS | +21 | +16 | +0.8 | +16.8 | 4,747 |

| 2023 | SS | −3 | −2 | +0.6 | −1.4 | 1,411 |
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. |
|---|---|---|---|
| 2026 | SS | 483 | +5.0 |
| 2025 | SS | 486 | +7.1 |
| 2024 | SS | 556 | +7.5 |
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.
