Non-MLB
Although they have not thrown an MLB pitch in 2024, Chris Britton threw 527 pitches that were tracked by the PITCHf/x system between 2007 and 2008, all of them occuring in the MLB Regular Season. In 2008, they relied primarily on their Fourseam Fastball (88mph) and Slider (78mph). He also rarely threw a Change (75mph).
In 2008, compared to other RHP:
Their fourseam fastball comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, results in somewhat more flyballs compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their slider comes in below hitting speed, generates fewer whiffs/swing compared to other pitchers' sliders, results in more flyballs compared to other pitchers' sliders, has primarily 12-6 movement and has some two-plane movement. Their change (take this with a grain of salt because they've only thrown 6 of them in 2008) comes in below hitting speed, has surprising cut action, generates fewer whiffs/swing compared to other pitchers' changeups, results in more flyballs compared to other pitchers' changeups and has some natural sink to it.
