His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, has well above average velo and has slight armside run. His change generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone, is much firmer than usual and has slight armside fade. His sinker is thrown at a speed that's borderline unfair, has an obvious tail, generates a very high amount of groundballs compared to other pitchers' sinkers, generates more whiffs/swing compared to other pitchers' sinkers and has some natural sinking action. His slider has primarily 12-6 movement, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement.
