  • Detroit’s roster as it stands starts at LF · 551 PA · 3.0 WAR in the role
  • Injured list 2026: Right hamstring strain (Aug 12–Sep 1)
  • Trade read Available at a price: DET sits on the contender line (52% playoff odds, within a projected win of 50%), so it could buy or sell; control through 2028.
  • PNC Park Pittsburgh’s home park: +2.9 runs per 600 PA against an average park (+0.28 wins over 562 PA; his WAR leaves this out); home runs ×1.00 (×0.99 for left-handed hitters as a group). Park Fit →

Does the most damage down and in (+5.3 vs. league per 100; 2.5 standard errors on 84 pitches, inside the noise for the best of nine cells).

Weakest up over the middle (−0.8), but only 0.4 standard errors from average on 131 pitches: no in-zone spot to attack yet.

Runs per 100 pitches vs. an average LHB: better · worse. Catcher’s view · 2,245 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).
