Basic description of 2015 pitches compared to other RHP:
His slider is basically never swung at and missed compared to other pitchers' sliders, is much harder than usual and has less than expected depth. His fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers and has slightly below average velo. His curve has below average velo, generates more whiffs/swing compared to other pitchers' curves, has a sharp downward bite and has slight glove-side movement. His change results in many more groundballs compared to other pitchers' changeups. His sinker (take this with a grain of salt because he's only thrown 9 of them in 2015) is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has little sinking action compared to a true sinker and has slightly below average velo.
