Milwaukee Brewers
Although they have not thrown an MLB pitch in 2024, Darin Ruf threw 35 pitches that were tracked by the PITCHf/x system between 2021 and 2022, all of them occuring in the MLB Regular Season. In 2022, they relied primarily on their Fourseam Fastball (60mph).
In 2022, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 14 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, has much less armside movement than typical and results in somewhat more flyballs compared to other pitchers' fourseamers.
