Basic description of 2015 pitches compared to other RHP:
His fourseam fastball has slight armside run and has slightly below average velo. His change generates more whiffs/swing compared to other pitchers' changeups, has a lot of backspin and has slightly below average velo. His curve is a real worm killer that generates an extreme number of groundballs compared to other pitchers' curves and has a sharp downward bite. His sinker is basically never swung at and missed compared to other pitchers' sinkers, generates a very high amount of groundballs compared to other pitchers' sinkers, has little sinking action compared to a true sinker and has slightly below average velo. His cutter (take this with a grain of salt because he's only thrown 6 of them in 2015) explodes on the hitter, generates an extremely high number of swings & misses compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has surprisingly little cutting action.
