His fourseam fastball has slightly above average velo. His cutter is blazing fast, has good "rise" and results in somewhat more groundballs compared to other pitchers' cutters. His curve generates an extremely high number of swings & misses compared to other pitchers' curves, has little depth, results in somewhat more flyballs compared to other pitchers' curves and has slight glove-side movement. His sinker is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, has slightly above average velo and has some natural sinking action. His change generates a high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in many more groundballs compared to other pitchers' changeups and has slight armside fade.
