Their slider sweeps across the zone, results in more flyballs compared to other pitchers' sliders and has some two-plane movement. 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, has some natural sinking action and has well above average velo. Their cutter has heavy sink, is an extreme flyball pitch compared to other pitchers' cutters, has slightly above average velo and has strong cutting action. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has well above average velo, has slight armside run and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 18 of them in 2026) is thrown extremely hard, has surprising cut action, dives down out of the zone, generates fewer whiffs/swing compared to other pitchers' changeups and results in more flyballs compared to other pitchers' changeups. Their curve (take this with a grain of salt because they've only thrown 5 of them in 2026) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' curves, has primarily 12-6 movement and results in somewhat more flyballs compared to other pitchers' curves.
