In 2025, compared to other LHP:
Their fourseam fastball has heavy sinking action, generates a very high amount of groundballs compared to other pitchers' fourseamers, generates more whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and has slight armside run. Their slider comes in below hitting speed, sweeps across the zone, generates a high number of swings & misses compared to other pitchers' sliders and results in somewhat more flyballs compared to other pitchers' sliders. Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups and dives down out of the zone. Their sinker has heavy sinking action and results in more flyballs compared to other pitchers' sinkers.
