Their change results in somewhat more flyballs compared to other pitchers' changeups, has slight armside fade, has slightly below average velo and has some natural sink to it. Their splitter has dives down out of the zone, is basically never swung at and missed compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters and has slight cut action. Their slider (take this with a grain of salt because they've only thrown 16 of them in 2020) is basically never swung at and missed compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has primarily 12-6 movement. Their fourseam fastball (take this with a grain of salt because they've only thrown 2 of them in 2020) generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has heavy sinking action, is an extreme flyball pitch compared to other pitchers' fourseamers and has below average velo.
