Cleveland Guardians
Although they have not thrown an MLB pitch in 2023, Anthony Gose threw 565 pitches that were tracked by the PITCHf/x system between 2020 and 2022, including pitches thrown in the MLB Regular Season, The World Baseball Classic and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (97mph) and Slider (86mph). He also rarely threw a Change (89mph).
In 2022, compared to other LHP:
Their fourseam fastball is thrown at a speed that's borderline unfair, generates more whiffs/swing compared to other pitchers' fourseamers, has less armside movement than typical and results in more flyballs compared to other pitchers' fourseamers. Their slider is thrown extremely hard, generates an extremely high number of swings & misses compared to other pitchers' sliders and has exceptional depth. Their change (take this with a grain of salt because they've only thrown 1 of them in 2022) is thrown extremely hard, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action and is an extreme flyball pitch compared to other pitchers' changeups.
