In 2026, compared to other LHP:
Their sinker has heavy sinking action, generates more whiffs/swing compared to other pitchers' sinkers, results in many more groundballs compared to other pitchers' sinkers and has less armside run than typical. Their change is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and is slightly firmer than usual. Their slider is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, results in somewhat more groundballs compared to other pitchers' sliders and has some two-plane movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 10 of them in 2026) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has some natural sinking action, has slightly above average velo and has slightly less natural movement than typical.
