Seattle Mariners
Although they have not thrown an MLB pitch in 2026, Jason Vosler threw 77 pitches that were tracked by the PITCHf/x system between 2023 and 2024, all of them occuring in the MLB Regular Season. In 2024, they relied primarily on their Fourseam Fastball (61mph).
In 2024, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 9 of them in 2024) comes in below hitting speed, has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, has an obvious tail and is an extreme flyball pitch compared to other pitchers' fourseamers.
