What stands out

  • It came on the smallest sample here: 520 batted balls over 1,766 pitches seen, the fewest in this group.
  • Top-end power intact: 90th-percentile exit velocity 106.1 mph.
  • Average exit velocity 83.4 mph; four-seam fastballs were 29.6% of his diet.
Reading note

Descriptive only, from a single 2025 Statcast pull (>=300 pitches-faced floor). His 1,766 pitches and 520 batted balls are the smallest sample in this group, so every rate here carries more sampling noise than the higher-volume hitters. Estimated wOBA on contact is a batted-ball model over those 520 balls and ignores walks and strikeouts. No swing/miss or launch-angle column in this pull. Not park- or opponent-adjusted; not a prediction. 'Fewest in this group' is scoped to these twelve hitters.
