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 high 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 and has short glove-side cut. His sinker has surprisingly little armside run, has well above average velo and has little sinking action compared to a true sinker.
