In 2026, compared to other LHP:
Their slider sweeps across the zone, has below average velo and results in somewhat more flyballs compared to other pitchers' sliders. Their cutter (take this with a grain of salt because they've only thrown 14 of them in 2026) is basically never swung at and missed compared to other pitchers' cutters, has extreme cut action, is an extreme flyball pitch compared to other pitchers' cutters and has some natural sink. Their sinker (take this with a grain of salt because they've only thrown 9 of them in 2026) has heavy sinking action, is basically never swung at and missed compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has slightly below average velo. Their change (take this with a grain of salt because they've only thrown 4 of them in 2026) is basically never swung at and missed compared to other pitchers' changeups, dives down out of the zone, is an extreme flyball pitch compared to other pitchers' changeups, has slight cut action and has slightly below average velo. Their slow curve (take this with a grain of salt because they've only thrown 2 of them in 2026) is a real yakker that's separated from their other curveball due to its big drop and slow speed. Their fourseam fastball (take this with a grain of salt because they've only thrown 1 of them in 2026) has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has below average velo and has less armside movement than typical.
