In 2022, compared to other RHP:
His sinker is thrown at a speed that's borderline unfair, has an obvious tail, generates more whiffs/swing compared to other pitchers' sinkers, results in many more groundballs compared to other pitchers' sinkers and has some natural sinking action. His slider generates a high number of swings & misses compared to other pitchers' sliders, is much harder than usual and has some two-plane movement. His change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, has an obvious armside fade, generates a high number of swings & misses compared to other pitchers' changeups and has some natural sink to it.
