Houston Astros
Although they have not thrown an MLB pitch in 2024, Aaron Heilman threw 4,976 pitches that were tracked by the PITCHf/x system between 2007 and 2012, including pitches thrown in the MLB Regular Season and Spring Training. In 2012, they relied primarily on their Sinker (92mph) and Change (81mph), also mixing in a Slider (82mph) and Splitter (85mph).
In 2012, compared to other RHP:
Their sinker has an obvious tail and generates more whiffs/swing compared to other pitchers' sinkers. Their change (take this with a grain of salt because they've only thrown 14 of them in 2012) generates an extremely high number of swings & misses compared to other pitchers' changeups, has an obvious armside fade, dives down out of the zone, results in more flyballs compared to other pitchers' changeups and has slightly below average velo. Their slider (take this with a grain of salt because they've only thrown 6 of them in 2012) generates an extremely high number of swings & misses compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders and has some two-plane movement. Their splitter (take this with a grain of salt because they've only thrown 4 of them in 2012) has dives down out of the zone, is basically never swung at and missed compared to other pitchers' splitters and is an extreme flyball pitch compared to other pitchers' splitters.
