His slider is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sliders, has exceptional depth, generates more whiffs/swing compared to other pitchers' sliders and has primarily 12-6 movement. His sinker is thrown at a speed that's borderline unfair, has an obvious tail and has some natural sinking action. His change is thrown extremely hard, has an obvious armside fade and results in somewhat more flyballs compared to other pitchers' changeups. His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is blazing fast, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has slight armside run.
