In 2025, compared to other RHP:
Their slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has exceptional depth, has primarily 12-6 movement and is much harder than usual. Their fourseam fastball results in somewhat more flyballs compared to other pitchers' fourseamers, has slightly above average velo and has slightly less natural movement than typical. Their curve is thrown extremely hard, has primarily 12-6 movement and has a sharp downward bite. Their cutter (take this with a grain of salt because they've only thrown 7 of them in 2025) generates a high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has slightly above average velo.
