Miami Marlins
Although they have not thrown an MLB pitch in 2025, Matt Mervis threw 37 pitches that were tracked by the PITCHf/x system in 2024, all of them occuring in the MLB Regular Season. In 2024, they relied primarily on their Change (55mph), also mixing in a Fourseam Fastball (83mph).
In 2024, compared to other RHP:
Their change comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has a lot of backspin and results in somewhat more flyballs compared to other pitchers' changeups. Their fourseam fastball (take this with a grain of salt because they've only thrown 3 of them in 2024) 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, has some natural sinking action and has slight armside run.
