Their change generates fewer whiffs/swing compared to other pitchers' changeups, is much firmer than usual, has slight armside fade and has some natural sink to it. Their slider has exceptional depth, has short glove-side cut and results in somewhat more flyballs compared to other pitchers' sliders.
