Basic description of 2019 pitches compared to other RHP:
His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is blazing fast, has some natural sinking action and has slight armside run. His cutter is thrown at a speed that's borderline unfair and is basically never swung at and missed compared to other pitchers' cutters. His curve generates a high number of swings & misses compared to other pitchers' curves, is slightly harder than usual, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves. His splitter generates fewer whiffs/swing compared to other pitchers' splitters, is much firmer than usual, results in many more groundballs compared to other pitchers' splitters and has some natural sink to it. His slider results in more flyballs compared to other pitchers' sliders, has short glove-side cut and has some two-plane movement.
