Cincinnati Reds
Although they have not thrown an MLB pitch in 2024, Jason Marquis threw 15,164 pitches that were tracked by the PITCHf/x system between 2007 and 2015, including pitches thrown in the MLB Regular Season and Spring Training. In 2015, they relied primarily on their Sinker (89mph) and Splitter (79mph), also mixing in a Slider (83mph). He also rarely threw a Curve (72mph).
In 2015, compared to other RHP:
Their sinker has heavy sinking action, has below average velo and has slight armside run. Their splitter comes in below hitting speed, results in more flyballs compared to other pitchers' splitters and has some natural sink to it. Their slider has primarily 12-6 movement and results in somewhat more groundballs compared to other pitchers' sliders. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2015) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has slight glove-side movement.
