Their slider is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement. Their cutter generates a high number of swings & misses compared to other pitchers' cutters, results in somewhat more groundballs compared to other pitchers' cutters, has some natural sink and has strong cutting action. Their fourseam fastball has heavy sinking action, has below average velo, has less armside movement than typical and results in somewhat more groundballs compared to other pitchers' fourseamers. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has some natural sinking action.
