Triple-A Sacramento activated Guzman (elbow) from its injured list Thursday and assigned him to Double-A Richmond.
Guzman debuted for the Double-A club Friday, working one inning while giving up one earned run on one hit and one walk. The 26-year-old right-hander previously had a cup of coffee in the majors with the Marlins in 2020 but has been sidelined for most of the 2021 and 2022 seasons due to right elbow injuries.
