Bars show where this card sits within its own pack (485 mlb batters), by simple rank of the measured value. Higher is only higher -- no quality judgement is implied.

What stands out

  • 82.1 mph average exit velocity is well below the group's power hitters.
  • The 90th-percentile figure, 100.9 mph, shows the top end is muted too.
  • He saw 1,981 pitches with a 49.5 percent rulebook-zone rate.
Reading note

Descriptive only, from a single 2025 Statcast pull (pitches_faced_2025>=300 floor, 485 of 671 batters). The contact numbers -- exit velocity and estimated wOBA on contact -- cover the batted balls only, not every pitch seen, and estimated wOBA on contact is a batted-ball model: it says nothing about walks, strikeouts, or actual results. This pull carries no swing/miss or launch-angle column, so there is no whiff rate and no barrel profile here. Not park-, role-, or opponent-adjusted, and not a prediction.
