In 2022, compared to other RHP:
His fourseam fastball has some natural sinking action, has well above average velo and has slight armside run. His splitter is a real worm killer that generates an extreme number of groundballs compared to other pitchers' splitters, is much firmer than usual, has some natural sink to it and has slight armside fade. His curve is a prototypical pitch with few remarkable qualities. His slider results in many more groundballs compared to other pitchers' sliders and has short glove-side cut. His cutter is basically never swung at and missed compared to other pitchers' cutters, results in somewhat more flyballs compared to other pitchers' cutters and has slightly above average velo.
