In 2026, compared to other RHP:
Their fourseam fastball generates a high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and has slight armside run. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, has sweeping glove-side movement and results in somewhat more flyballs compared to other pitchers' curves. Their sinker is basically never swung at and missed compared to other pitchers' sinkers, has an obvious tail and has some natural sinking action. Their slider comes in below hitting speed, sweeps across the zone, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their cutter results in more flyballs compared to other pitchers' cutters and has strong cutting action. Their change is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups and dives down out of the zone.
