Oakland Athletics
Although they have not thrown an MLB pitch in 2026, Michael Stefanic threw 22 pitches that were tracked by the PITCHf/x system between 2024 and 2025, all of them occuring in the MLB Regular Season. In 2025, they relied primarily on their Fourseam Fastball (61mph).
In 2025, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 7 of them in 2025) 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 natural sinking action.
