In 2025, compared to other RHP:
Their fourseam fastball has much less armside movement than typical, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their cutter is basically never swung at and missed compared to other pitchers' cutters, has sweeping cut action, results in somewhat more flyballs compared to other pitchers' cutters and has some natural sink. Their curve has an exceptional bite, has below average velo and results in somewhat more flyballs compared to other pitchers' curves. Their slider is basically never swung at and missed compared to other pitchers' sliders, has exceptional depth, has below average velo, has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' sliders. Their change results in somewhat more groundballs compared to other pitchers' changeups, has slightly below average velo and has some natural sink to it. Their sinker (take this with a grain of salt because they've only thrown 5 of them in 2025) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical and has little sinking action compared to a true sinker.
