Oakland Athletics
Although they have not thrown an MLB pitch in 2024, Homer Bailey threw 23,309 pitches that were tracked by the PITCHf/x system between 2007 and 2020, including pitches thrown in the MLB Regular Season and Spring Training. In 2020, they relied primarily on their Fourseam Fastball (91mph), Slider (84mph) and Splitter (82mph), also mixing in a Curve using a Knuckle Curve grip (75mph).
In 2020, compared to other RHP:
Their fourseam fastball is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers and has slightly below average velo. Their slider results in more flyballs compared to other pitchers' sliders. Their splitter is an extreme flyball pitch compared to other pitchers' splitters, has slight cut action, has some natural sink to it and has below average velo. Their curve using a knuckle curve grip (take this with a grain of salt because they've only thrown 19 of them in 2020) is basically never swung at and missed compared to other pitchers' curves, has a sharp downward bite, results in somewhat more flyballs compared to other pitchers' curves, has slight glove-side movement and has slightly below average velo.
