Where he does damage, and where to pitch him
Does the most damage middle-middle (+4.9 vs. league per 100; 2.4 standard errors on 117 pitches, inside the noise for the best of nine cells).
Weakest down and in (−3.4), but only 1.5 standard errors from average on 53 pitches: no in-zone spot to attack yet.
Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,706 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).

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.

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 2025, the biggest loss came toward 3B line (−2 outs): a coaching target.
Tools (percentile; arm among 3Bs)| Season | Zone | Balls | Outs vs. exp. |
|---|---|---|---|
| 2026 | 3B | 188 | −11.0 |
| 2025 | 1B | 130 | +0.3 |
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.
