In 2022, compared to other RHP:
His fourseam fastball is straight as an arrow, generates a high number of swings & misses compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers and has essentially average velo. His slider is basically never swung at and missed compared to other pitchers' sliders and results in many more groundballs compared to other pitchers' sliders. His curve is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth, is slightly harder than usual and has primarily 12-6 movement. His change (take this with a grain of salt because he's only thrown 19 of them in 2022) generates more whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups, has slight cut action and is slightly firmer than usual.
