Houston Astros
Although they have not thrown an MLB pitch in 2024, Joe Inglett threw 6 pitches that were tracked by the PITCHf/x system in 2010, all of them occuring in the MLB Regular Season. In 2010, they relied primarily on their Fourseam Fastball (55mph).
In 2010, compared to other RHP:
Their fourseam fastball (take this with a grain of salt because they've only thrown 6 of them in 2010) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' fourseamers and has much less armside movement than typical.
