Philadelphia Phillies
Although they have not thrown an MLB pitch in 2024, Steve Geltz threw 1,798 pitches that were tracked by the PITCHf/x system between 2012 and 2017, including pitches thrown in the MLB Regular Season and Spring Training. In 2017, they relied primarily on their Fourseam Fastball (92mph) and Splitter (83mph), also mixing in a Slider (80mph).
In 2017, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 17 of them in 2017) is an extreme flyball pitch compared to other pitchers' fourseamers, has essentially average velo, has slightly less natural movement than typical and has some added backspin. Their splitter (take this with a grain of salt because they've only thrown 11 of them in 2017) has dives down out of the zone, is basically never swung at and missed compared to other pitchers' splitters, has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters and has slightly below average velo. Their slider (take this with a grain of salt because they've only thrown 7 of them in 2017) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement.
