In 2014, he relied primarily on his Fourseam Fastball (93mph), also mixing in a Curve
Basic description of 2014 pitches compared to other RHP:
His fourseam fastball has good "rising" action, has essentially average velo and has slightly less natural movement than typical. His curve has a sharp downward bite and results in somewhat more groundballs compared to other pitchers' curves. His slider results in many more groundballs compared to other pitchers' sliders and has short glove-side cut. His change generates fewer whiffs/swing compared to other pitchers' changeups, has a lot of backspin, results in somewhat more flyballs compared to other pitchers' changeups and has slightly below average velo. His sinker (take this with a grain of salt because he's only thrown 7 of them in 2014) 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.
