In 2025, compared to other RHP:
Their slider has exceptional depth, generates a high number of swings & misses compared to other pitchers' sliders and results in somewhat more groundballs compared to other pitchers' sliders. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has well above average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their sinker is blazing fast. Their change is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, results in many more groundballs compared to other pitchers' changeups and has some natural sink to it. Their curve is basically never swung at and missed compared to other pitchers' curves, is slightly harder than usual, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. Their cutter (take this with a grain of salt because they've only thrown 2 of them in 2025) is basically never swung at and missed compared to other pitchers' cutters, is blazing fast, is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has some natural sink.
