His fourseam fastball results in somewhat more flyballs compared to other pitchers' fourseamers, has slightly above average velo and has slightly less natural movement than typical. His slider results in somewhat more flyballs compared to other pitchers' sliders. His curve has an exceptional bite, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' curves and has slight glove-side movement. His change is slightly firmer than usual. His sinker has surprisingly little armside run, has little sinking action compared to a true sinker, results in somewhat more groundballs compared to other pitchers' sinkers and has slightly above average velo.
