Basic description of 2019 pitches compared to other LHP:
His sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair and has surprisingly little armside run. His slider is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' sliders and has less than expected depth. His fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair, generates fewer whiffs/swing compared to other pitchers' fourseamers and has slightly less natural movement than typical. His curve is thrown extremely hard, results in more flyballs compared to other pitchers' curves, has little depth and has primarily 12-6 movement.
