In 2025, compared to other RHP:
Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, has slight armside run and has slightly above average velo. Their slider results in more flyballs compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has an obvious tail, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 13 of them in 2025) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has an obvious armside fade and results in more flyballs compared to other pitchers' changeups.
