In 2025, compared to other RHP:
Their fourseam fastball comes in below hitting speed, has heavy sinking action and has much less armside movement than typical. Their slider comes in below hitting speed, generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has less than expected depth. Their change dives down out of the zone, has slight armside fade and has slightly below average velo. Their sinker is so slow that it is substantially gravitational, has heavy sinking action and results in somewhat more flyballs compared to other pitchers' sinkers.
