In the first major roster move of the season, according to Jake Kaplan of theathletic.com, the Astros reshuffled their bullpen staff. Houston has sent Valdez down to their Triple-A affiliate Round Rock Express and brought up Guduan from the same team to join the Astros bullpen.
Valdez and Guduan were the final two left-handed relief pitchers that were battling it out in Spring Training for the final spot in the pen. Valdez ultimately won out, traveling with the team from Florida to Houston to start the season.
Valdez has only appeared in two games this season pitching three innings.
