Basic description of 2015 pitches compared to other RHP:
His sinker is a prototypical pitch with few remarkable qualities. His change is thrown extremely hard, dives down out of the zone and generates a very high amount of groundballs compared to other pitchers' changeups. His curve generates a very high amount of groundballs compared to other pitchers' curves, generates more whiffs/swing compared to other pitchers' curves, has a sharp downward bite, is slightly harder than usual and has slight glove-side movement. His fourseam fastball has some natural sinking action, has essentially average velo, results in somewhat more groundballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. His slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has exceptional depth and has primarily 12-6 movement. His cutter is basically never swung at and missed compared to other pitchers' cutters, is blazing fast, has little cutting action and has some natural sink.
