In 2024, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair and has slight armside run. Their slider is thrown extremely hard, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their cutter is blazing fast, generates a very high amount of groundballs compared to other pitchers' cutters, generates more whiffs/swing compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their curve (take this with a grain of salt because they've only thrown 16 of them in 2024) is thrown extremely hard, results in more flyballs compared to other pitchers' curves and has primarily 12-6 movement. Their change (take this with a grain of salt because they've only thrown 1 of them in 2024) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight cut action and has an extreme amount of backspin.
