Colorado Rockies
Although they have not thrown an MLB pitch in 2024, Justin Speier threw 2,570 pitches that were tracked by the PITCHf/x system between 2007 and 2010, including pitches thrown in the MLB Regular Season and Spring Training. In 2010, they relied primarily on their Sinker (89mph) and Splitter (82mph), also mixing in a Cutter (83mph).
In 2010, compared to other RHP:
Their sinker (take this with a grain of salt because they've only thrown 6 of them in 2010) generates an extremely high number of swings & misses compared to other pitchers' sinkers, is an extreme flyball pitch compared to other pitchers' sinkers, has below average velo and has little sinking action compared to a true sinker. Their splitter (take this with a grain of salt because they've only thrown 5 of them in 2010) generates an extremely high number of swings & misses compared to other pitchers' splitters, has surprising cut action, is an extreme flyball pitch compared to other pitchers' splitters, has some natural sink to it and has slightly below average velo. Their cutter (take this with a grain of salt because they've only thrown 1 of them in 2010) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' cutters, is an extreme flyball pitch compared to other pitchers' cutters and has surprisingly little cutting action.
