In 2022, compared to other LHP:
His slider sweeps across the zone and results in somewhat more flyballs compared to other pitchers' sliders. His fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has some natural sinking action, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. His change is thrown extremely hard, dives down out of the zone and results in many more groundballs compared to other pitchers' changeups. His curve has sweeping glove-side movement, generates fewer whiffs/swing compared to other pitchers' curves and has a sharp downward bite.
