Although they have not thrown an MLB pitch in 2023, Austin Voth threw 4,667 pitches that were tracked by the PITCHf/x system between 2018 and 2022, including pitches thrown in the MLB Regular Season and Spring Training. In 2022, they relied primarily on their Fourseam Fastball (94mph), Curve (78mph) and Cutter (90mph). He also rarely threw a Slider (84mph) and Change (87mph).
In 2022, compared to other RHP:
His fourseam fastball has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. His curve has sweeping glove-side movement and has a sharp downward bite. His cutter has some natural sink. His slider sweeps across the zone, is an extreme flyball pitch compared to other pitchers' sliders and has less than expected depth. His change (take this with a grain of salt because he's only thrown 14 of them in 2022) generates fewer whiffs/swing compared to other pitchers' changeups, is much firmer than usual, results in more flyballs compared to other pitchers' changeups and has a lot of backspin.
