In 2025, compared to other RHP:
Their fourseam fastball has much less armside movement than typical, generates more whiffs/swing compared to other pitchers' fourseamers and has essentially average velo. 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 and has below average velo. Their change results in somewhat more groundballs compared to other pitchers' changeups and has slightly below average velo. Their slider is basically never swung at and missed compared to other pitchers' sliders and has exceptional depth. 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.
