In 2025, compared to other RHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers and has well above average velo. Their change is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and results in somewhat more flyballs compared to other pitchers' changeups. Their slider is thrown extremely hard, is an extreme flyball pitch compared to other pitchers' sliders and has primarily 12-6 movement. Their curve has an exceptional bite, generates an extremely high number of swings & misses compared to other pitchers' curves, has primarily 12-6 movement, results in more flyballs compared to other pitchers' curves and is slightly harder than usual. Their cutter (take this with a grain of salt because they've only thrown 13 of them in 2025) generates fewer whiffs/swing compared to other pitchers' cutters, has slightly above average velo and has some natural sink.
