In 2024, compared to other RHP:
Their sinker has slight armside run. Their slider has exceptional depth, generates a high number of swings & misses compared to other pitchers' sliders, results in many more groundballs compared to other pitchers' sliders and has primarily 12-6 movement. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slight armside run. Their change (take this with a grain of salt because they've only thrown 4 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has slight armside fade.
