In 2022, compared to other RHP:
His fourseam fastball has essentially average velo, results in somewhat more flyballs compared to other pitchers' fourseamers and has some added backspin. His change is a prototypical pitch with few remarkable qualities. His curve has an exceptional bite and has primarily 12-6 movement. His slider generates fewer whiffs/swing compared to other pitchers' sliders and has primarily 12-6 movement.
