Their slider is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has much less depth than expected and has primarily 12-6 movement. Their fourseam fastball has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their sinker is basically never swung at and missed compared to other pitchers' sinkers, results in more flyballs compared to other pitchers' sinkers and has less armside run than typical. Their curve is basically never swung at and missed compared to other pitchers' curves.
