In 2024, compared to other RHP:
Their slider sweeps across the zone, has exceptional depth, generates a high number of swings & misses compared to other pitchers' sliders and results in more flyballs compared to other pitchers' sliders. Their sinker is thrown at a speed that's borderline unfair, generates a high number of swings & misses compared to other pitchers' sinkers, results in somewhat more groundballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their cutter generates an extremely high number of swings & misses compared to other pitchers' cutters, results in more flyballs compared to other pitchers' cutters, has slightly above average velo and has some natural sink. Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2024) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action and has well above average velo.
