Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is blazing fast, results in more flyballs compared to other pitchers' fourseamers and has some natural sinking action. Their sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, is blazing fast, has slight armside run and has some natural sinking action. Their slider has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders, has short glove-side cut and results in somewhat more flyballs compared to other pitchers' sliders. Their change (take this with a grain of salt because they've only thrown 1 of them in 2025) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone, is an extreme flyball pitch compared to other pitchers' changeups and has slight cut action.
