Minnesota Twins
Although they have not thrown an MLB pitch in 2024, Locke St. John threw 240 pitches that were tracked by the PITCHf/x system between 2019 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Slider (75mph) and Change (83mph), also mixing in a Fourseam Fastball (87mph), Sinker (87mph) and Cutter (87mph).
In 2023, compared to other LHP:
Their slider (take this with a grain of salt because they've only thrown 8 of them in 2023) comes in below hitting speed, generates an extremely high number of swings & misses compared to other pitchers' sliders, sweeps across the zone, results in more flyballs compared to other pitchers' sliders and has some two-plane movement. Their change (take this with a grain of salt because they've only thrown 5 of them in 2023) generates an extremely high number of swings & misses compared to other pitchers' changeups, dives down out of the zone and is an extreme flyball pitch compared to other pitchers' changeups. Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2023) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers and is an extreme flyball pitch compared to other pitchers' fourseamers. Their sinker (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' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has surprisingly little armside run, has slightly below average velo and has some natural sinking action. Their cutter (take this with a grain of salt because they've only thrown 2 of them in 2023) is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has good "rise".
