In 2026, compared to other RHP:
Their slider sweeps across the zone, results in more flyballs compared to other pitchers' sliders, has below average velo and has some two-plane movement. Their fourseam fastball generates more whiffs/swing compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers and has essentially average velo. Their sinker is an extreme flyball pitch compared to other pitchers' sinkers, generates more whiffs/swing compared to other pitchers' sinkers and has some natural sinking action. Their splitter is basically never swung at and missed compared to other pitchers' splitters, has some natural sink to it, is slightly firmer than usual and results in somewhat more groundballs compared to other pitchers' splitters. Their change (take this with a grain of salt because they've only thrown 1 of them in 2026) is basically never swung at and missed compared to other pitchers' changeups, is much firmer than usual and results in more flyballs compared to other pitchers' changeups.
