In 2026, compared to other LHP:
Their fourseam fastball has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is thrown at a speed that's borderline unfair and has slight armside run. Their curve is thrown extremely hard and is an extreme flyball pitch compared to other pitchers' curves. Their change is thrown extremely hard, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' changeups, dives down out of the zone and has slight armside fade. Their slider is thrown extremely hard, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their sinker (take this with a grain of salt because they've only thrown 16 of them in 2026) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is thrown at a speed that's borderline unfair, is an extreme flyball pitch compared to other pitchers' sinkers, has less armside run than typical and has some natural sinking action.
