Where he does damage, and where to pitch him
Does the most damage down over the middle (+3.4 vs. league per 100; 1.7 standard errors on 108 pitches, inside the noise for the best of nine cells).
Weakest middle-in (−3.9), but only 1.8 standard errors from average on 75 pitches: no in-zone spot to attack yet.
Runs per 100 pitches vs. an average RHB: better · worse. Catcher’s view · 1,553 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).

At 3B in 2026, the biggest loss came back (−2 outs): a coaching target.
