In 2026, compared to other LHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, has less armside movement than typical and has well above average velo. Their slider is thrown extremely hard and generates more whiffs/swing compared to other pitchers' sliders. Their change dives down out of the zone, generates more whiffs/swing compared to other pitchers' changeups and results in somewhat more flyballs compared to other pitchers' changeups. Their sinker is blazing fast, has surprisingly little armside run and results in more flyballs compared to other pitchers' sinkers. Their curve is an extreme flyball pitch compared to other pitchers' curves and has a sharp downward bite.
