The Astros are set to select the contract of first baseman Jon Singleton from Triple-A Sugar Land, Singleton himself tells Kristie Rieken of the Associated Press (Twitter link). He’s on his way to join the team in Baltimore. A corresponding 40-man roster move will need to be announced, though Houston already opened a spot on the 26-man roster by optioning Corey Julks to Triple-A earlier today.
More to come.
