In 2025, compared to other RHP:
Their slider sweeps across the zone, has exceptional depth, generates fewer whiffs/swing compared to other pitchers' sliders and results in somewhat more flyballs compared to other pitchers' sliders. Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, has some natural sinking action, has well above average velo and has slightly less natural movement than typical. Their cutter has heavy sink, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' cutters, has slightly above average velo and has strong cutting action. Their sinker generates fewer whiffs/swing compared to other pitchers' sinkers, has well above average velo, results in somewhat more flyballs compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 10 of them in 2025) is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
