In 2023, they relied primarily on their Slider (82mph), Sinker (87mph) and Change (80mph). He also rarely threw a Fourseam Fastball (91mph).
In 2023, compared to other LHP:
Their slider generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders and has less than expected depth. Their sinker is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run and has below average velo. Their change (take this with a grain of salt because they've only thrown 16 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' changeups, is an extreme flyball pitch compared to other pitchers' changeups and has slightly below average velo. Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2023) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has less armside movement than typical and has essentially average velo.
