In 2025, compared to other RHP:
Their fourseam fastball has less armside movement than typical and has slightly above average velo. Their slider is much harder than usual, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. Their cutter generates more whiffs/swing compared to other pitchers' cutters, results in somewhat more groundballs compared to other pitchers' cutters, has slightly above average velo, has some natural sink and has strong cutting action. Their change results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their curve (take this with a grain of salt because they've only thrown 18 of them in 2025) results in more flyballs compared to other pitchers' curves and is slightly harder than usual.
