Scouting Report
Acquired by the Marlins via international free agency in 2023 ($225k signing bonus)
October 2025: Benitez is coming off a frustrating age-19 season. In limited Low-A action, he only threw 57% of his pitches for strikes, which is a red flag for an aspiring starter.
Benitez's changeup has the potential to be a plus-plus offering. The 6'1" lefty gets nearly seven feet of extension during his delivery, but must do a better job repeating his mechanics.
