In 2022, compared to other RHP:
His fourseam fastball has some natural sinking action, has slightly above average velo and has slightly less natural movement than typical. His slider generates more whiffs/swing compared to other pitchers' sliders and is much harder than usual. His change is much firmer than usual and results in somewhat more flyballs compared to other pitchers' changeups. His curve (take this with a grain of salt because he's only thrown 8 of them in 2022) is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, is slightly harder than usual and has primarily 12-6 movement.
