In 2016, he has relied primarily on his Sinker (90mph), Change (87mph) and Curve (80mph), also mixing in a Fourseam Fastball (91mph) and Slider (84mph). He also rarely throws a Cutter (90mph).
Basic description of 2016 pitches compared to other RHP:
His sinker results in somewhat more flyballs compared to other pitchers' sinkers and has slightly below average velo. His change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone and is much firmer than usual. His curve has a sharp downward bite. His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is basically never swung at and missed compared to other pitchers' fourseamers, has some natural sinking action and has slightly below average velo. His slider is an extreme flyball pitch compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. His cutter (take this with a grain of salt because he's only thrown 13 of them in 2016) is an extreme flyball pitch compared to other pitchers' cutters, has surprisingly little cutting action and has slightly above average velo.
