Basic description of 2018 pitches compared to other LHP:
His fourseam fastball has heavy sinking action, has an obvious tail, generates fewer whiffs/swing compared to other pitchers' fourseamers, has essentially average velo and results in somewhat more groundballs compared to other pitchers' fourseamers. His change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone, generates a high number of swings & misses compared to other pitchers' changeups and has slight cut action. His slider has primarily 12-6 movement, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement.
