Plan for 2027
- 1 Approach medium ask Swing less at pitches out of the zone
Chases 38% of pitches out of the zone in 2026 (87th percentile for chasing). The Hitting Lab’s regressed swing-decision value is −0.88 per 100 pitches (2025–26 pooled; about −0.43 runs), past its −0.55 line, and chasing is the weak part (worse than 87% of MLB regulars, 2025–26). With no plan a chase rate like his drifts toward the median on its own (about 37% next year); the target beats that, and his earlier seasons count on 2026’s league basis (the 2026 zone raised chase rates league-wide).
Chase rate: 38% target 34% no plan ≈ 37% ≈6.2 runs/season (what his swing decisions cost a season vs. an average hitter at his 2027 plate appearances, on the Hitting Lab’s regressed value) Check at the end of the 2027 season · noise then ±2% Hitting Lab · decisions - 2 Health note low ask Medical note: check in before the winter program
Right elbow strain (10-day IL, May 31–Jun 26, 2026). He came back and played 30 games after it, so it doesn’t hold up the rest of the plan.
Health & Workload
Each goal is checked when his sample can tell the target from noise: the 2027 All-Star break if it can by then, else season’s end or the sample it needs; if no single season can, it’s a lean. Coach card

Where he does damage, and where to pitch him
Does the most damage up and away (+4.9 vs. league per 100; 2.1 standard errors on 42 pitches, inside the noise for the best of nine cells).
Weakest middle-middle (−2.4), but only 1.1 standard errors from average on 80 pitches: no in-zone spot to attack yet.
Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,184 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 | −7 | −5 | +0.8 | −4.2 | 2,829 |
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 SS in 2026, the biggest loss came toward 1B line (−5 outs): a coaching target.
Tools (percentile; arm among SSs)| Season | Zone | Balls | Outs vs. exp. |
|---|---|---|---|
| 2026 | SS | 235 | +6.2 |
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.
