Philadelphia Phillies
Although they have not thrown an MLB pitch in 2025, Mark Appel threw 247 pitches that were tracked by the PITCHf/x system between 2022 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they relied primarily on their Sinker (95mph), Slider (84mph) and Cutter (91mph). He also rarely threw a Splitter (87mph).
In 2023, compared to other RHP:
Their sinker generates more whiffs/swing compared to other pitchers' sinkers and has well above average velo. Their slider generates an extremely high number of swings & misses compared to other pitchers' sliders, has exceptional depth and is an extreme flyball pitch compared to other pitchers' sliders. Their cutter is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters, has slightly above average velo and has some natural sink. Their splitter (take this with a grain of salt because they've only thrown 1 of them in 2023) is basically never swung at and missed compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters and is slightly firmer than usual.
