Miami Marlins
Although they have not thrown an MLB pitch in 2024, Preston Guilmet threw 609 pitches that were tracked by the PITCHf/x system between 2013 and 2021, all of them occuring in the MLB Regular Season. In 2021, they relied primarily on their Splitter (81mph) and Fourseam Fastball (89mph), also mixing in a Curve (78mph).
In 2021, compared to other RHP:
Their splitter (take this with a grain of salt because they've only thrown 15 of them in 2021) has dives down out of the zone, generates an extremely high number of swings & misses compared to other pitchers' splitters, is an extreme flyball pitch compared to other pitchers' splitters, has slight cut action and has below average velo. Their fourseam fastball (take this with a grain of salt because they've only thrown 11 of them in 2021) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers, is an extreme flyball pitch compared to other pitchers' fourseamers and has some added backspin. Their curve (take this with a grain of salt because they've only thrown 3 of them in 2021) generates an extremely high number of swings & misses compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves and has a sharp downward bite.
