In 2026, compared to other RHP:
Their sinker is thrown at a speed that's borderline unfair, results in many more groundballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their slider is thrown extremely hard. Their change is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, results in somewhat more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it. Their fourseam fastball is blazing fast, has some natural sinking action and has slight armside run. Their curve (take this with a grain of salt because they've only thrown 3 of them in 2026) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has primarily 12-6 movement.
