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, sweeps across the zone and has some two-plane movement. Their sinker is an extreme flyball pitch compared to other pitchers' sinkers, generates more whiffs/swing compared to other pitchers' sinkers, has slight armside run, has slightly above average velo and has some natural sinking action. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slight armside run. Their change dives down out of the zone, results in more flyballs compared to other pitchers' changeups and is slightly firmer than usual. Their curve (take this with a grain of salt because they've only thrown 13 of them in 2025) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' curves, has sweeping glove-side movement and results in more flyballs compared to other pitchers' curves.
