Toronto Blue Jays
Although they have not thrown an MLB pitch in 2024, Brian Serven threw 8 pitches that were tracked by the PITCHf/x system in 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (73mph).
In 2022, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 8 of them in 2022) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers and has much less armside movement than typical.
