In 2022, compared to other LHP:
His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. His change generates more whiffs/swing compared to other pitchers' changeups and has some natural sink to it. His slider is basically never swung at and missed compared to other pitchers' sliders and is much harder than usual.
