In 2025, they have relied primarily on their Slider (83mph) and Sinker (97mph), also mixing in a Cutter (90mph), Fourseam Fastball (97mph) and Change (91mph). He also rarely throws a Curve (82mph).
In 2025, compared to other RHP:
Their slider sweeps across the zone and results in somewhat more flyballs compared to other pitchers' sliders. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, has an obvious tail and has some natural sinking action. Their cutter has heavy sink, generates a 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 strong cutting action. Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, generates a high number of swings & misses compared to other pitchers' fourseamers, is blazing fast, has some natural sinking action and has slight armside run. Their change is thrown extremely hard, dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has slight armside fade. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2025) is basically never swung at and missed compared to other pitchers' curves, is much harder than usual, results in more flyballs compared to other pitchers' curves and has slight glove-side movement.
