Basic description of 2014 pitches compared to other RHP:
His fourseam fastball has less armside movement than typical, results in many more groundballs compared to other pitchers' fourseamers, has slightly above average velo and has some added backspin. His curve generates a huge number of swings & misses compared to other pitchers' curves, is much harder than usual, has a sharp downward bite and has slight glove-side movement. His slider has exceptional depth, has short glove-side cut and results in somewhat more flyballs compared to other pitchers' sliders. His sinker has surprisingly little armside run, has well above average velo and has little sinking action compared to a true sinker.
