Houston Astros
Although they have not thrown an MLB pitch in 2024, Steve Delabar threw 3,500 pitches that were tracked by the PITCHf/x system between 2011 and 2016, including pitches thrown in the MLB Regular Season and Spring Training. In 2016, they relied primarily on their Fourseam Fastball (94mph), also mixing in a Splitter (87mph) and Slider (87mph).
In 2016, compared to other RHP:
Their fourseam fastball generates an extremely high number of swings & misses compared to other pitchers' fourseamers, has essentially average velo and results in somewhat more flyballs compared to other pitchers' fourseamers. Their splitter is much firmer than usual, has some natural sink to it and results in somewhat more groundballs compared to other pitchers' splitters. Their slider (take this with a grain of salt because they've only thrown 11 of them in 2016) is basically never swung at and missed compared to other pitchers' sliders, is an extreme flyball pitch compared to other pitchers' sliders, is much harder than usual and has primarily 12-6 movement.
