To make room on the 40-man roster for the additions, the Astros outrighted right-hander Rogelio Armenteros, who was claimed by Arizona, and infielder Jack Mayfield, who was claimed by Atlanta. Mayfield appeared in 47 games for Houston in the past two seasons, while Armenteros missed the entire 2020 season while recovering from surgery to remove a bone spur in his throwing elbow.
Meanwhile, the Astros also completed two trades with the Reds on Friday in separate transactions. Right-hander Brandon Bailey, who appeared in five games for Houston last season, was traded to the Reds for cash. Houston also sent right-handed pitcher Fredy Medina to the Reds as the player to be named in the Aug. 9 trade for lefty reliever Brooks Raley.
Here’s more information on the five players added to the 40-man roster on Friday:
