Their sinker (take this with a grain of salt because they've only thrown 3 of them in 2025) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers and has slightly above average velo. Their change (take this with a grain of salt because they've only thrown 1 of them in 2025) 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.
