Non-MLB
Although they have not thrown an MLB pitch in 2025, Heath Hembree threw 7,091 pitches that were tracked by the PITCHf/x system between 2012 and 2024, including pitches thrown in the MLB Regular Season, the MLB Postseason, Spring Training and Fall/Winter Ball. In 2024, they relied primarily on their Slider (84mph) and Fourseam Fastball (94mph).
In 2024, compared to other RHP:
Their slider (take this with a grain of salt because they've only thrown 6 of them in 2024) is an extreme flyball pitch compared to other pitchers' sliders, has short glove-side cut and has less than expected depth. Their fourseam fastball (take this with a grain of salt because they've only thrown 9 of them in 2024) is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo and has slightly less natural movement than typical.
