Texas Rangers
Alan Trejo has thrown 69 pitches that have been tracked by the PITCHf/x system between 2023 and 2025, all of them occuring in the MLB Regular Season. In 2025, they have relied primarily on their Fourseam Fastball (83mph) and Change (58mph), also mixing in a Knuckleball (74mph). He also rarely throws a Curve (59mph).
In 2025, compared to other RHP:
Their fourseam fastball comes in below hitting speed, has heavy sinking action, is a real worm killer that generates an extreme number of groundballs compared to other pitchers' fourseamers, is basically never swung at and missed compared to other pitchers' fourseamers and has slightly less natural movement than typical. Their change (take this with a grain of salt because they've only thrown 17 of them in 2025) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' changeups, has surprising cut action, has a lot of backspin and results in somewhat more flyballs compared to other pitchers' changeups. Their knuckleball (take this with a grain of salt because they've only thrown 3 of them in 2025) flutters and floats unpredictably toward the plate. Their curve (take this with a grain of salt because they've only thrown 1 of them in 2025) comes in below hitting speed, is basically never swung at and missed compared to other pitchers' curves, results in more flyballs compared to other pitchers' curves, has little depth and has primarily 12-6 movement.
