Non-MLB
Although they have not thrown an MLB pitch in 2024, James Hoyt threw 1,912 pitches that were tracked by the PITCHf/x system between 2015 and 2021, including pitches thrown in the MLB Regular Season and Spring Training. In 2021, they relied primarily on their Slider (83mph), also mixing in a Sinker (91mph) and Fourseam Fastball (91mph). He also rarely threw a Splitter (88mph).
In 2021, compared to other RHP:
Their slider has primarily 12-6 movement, results in somewhat more flyballs compared to other pitchers' sliders and has some two-plane movement. Their sinker generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has slight armside run and has some natural sinking action. Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, results in more flyballs compared to other pitchers' fourseamers, has some natural sinking action and has slightly below average velo. Their splitter (take this with a grain of salt because they've only thrown 6 of them in 2021) is basically never swung at and missed compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters, is much firmer than usual and has some natural sink to it.
