In 2023, compared to other LHP:
Their sinker has heavy sinking action, is an extreme flyball pitch compared to other pitchers' sinkers and has well above average velo. Their change dives down out of the zone, generates a high number of swings & misses compared to other pitchers' changeups, is much firmer than usual and results in more flyballs compared to other pitchers' changeups. Their slider (take this with a grain of salt because they've only thrown 14 of them in 2023) sweeps across the zone, generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, results in more flyballs compared to other pitchers' fourseamers, has well above average velo and has slightly less natural movement than typical. Their cutter (take this with a grain of salt because they've only thrown 15 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' cutters, has heavy sink, has extreme cut action, results in somewhat more flyballs compared to other pitchers' cutters and has slightly above average velo.
