Non-MLB
Although they have not thrown an MLB pitch in 2024, Frank Schwindel threw 42 pitches that were tracked by the PITCHf/x system in 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (59mph) and Change (37mph). He also rarely threw a Slider (47mph).
In 2022, compared to other RHP:
Their fourseam fastball comes in below hitting speed, is an extreme flyball pitch compared to other pitchers' fourseamers and has some natural sinking action. Their change (take this with a grain of salt because they've only thrown 10 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, results in more flyballs compared to other pitchers' changeups and has a lot of backspin. Their slider (take this with a grain of salt because they've only thrown 2 of them in 2022) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sliders, sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders and has much less depth than expected.
