In 2025, compared to other RHP:
Their fourseam fastball is thrown at a speed that's borderline unfair, has some natural sinking action and results in somewhat more groundballs compared to other pitchers' fourseamers. Their slider generates more whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, is much harder than usual, has primarily 12-6 movement and has some two-plane movement. Their change is thrown extremely hard, dives down out of the zone, generates a high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their sinker is blazing fast, results in somewhat more groundballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their cutter (take this with a grain of salt because they've only thrown 4 of them in 2025) has heavy sink, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has well above average velo. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2025) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' curves and results in more flyballs compared to other pitchers' curves.
