Where he does damage, and where to pitch him
Does the most damage up and away (+1.2 vs. league per 100; 0.5 standard errors on 92 pitches, inside the noise for the best of nine cells).
Weakest middle-away (−4.3; 2.2 standard errors below average on 135 pitches). Pitchers should attack here.
Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,891 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 | 2B | −9 | −7 | −1.4 | −8.4 | 5,151 |
| 2025 | 2B | +6 | +5 | +0.8 | +5.8 | 4,576 |
| 2024 | 2B | +19 | +14 | −0.1 | +13.9 | 5,920 |
| 2023 | 2B | +16 | +12 | +2.0 | +14.0 | 5,911 |
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 2B in 2026, the biggest loss came toward 3B line (−5 outs): a coaching target.
Tools (percentile; arm among 2Bs)| Season | Zone | Balls | Outs vs. exp. |
|---|---|---|---|
| 2026 | 2B | 495 | +5.8 |
| 2025 | 2B | 415 | +10.7 |
| 2024 | 2B | 547 | +19.3 |
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.
