The Astros have designated right-hander Hector Ambriz for assignment, the team announced via Twitter. The move was made to create 40-man roster space for Eric Thames, who was claimed off waivers from the Orioles earlier today. Ambriz is represented by LSW Baseball.
Ambriz, 29, posted a 5.70 ERA, 6.7 K/9 and 3.5 BB/9 over 36 1/3 relief innings for Houston this season. The righty signed a minor league contract with the Astros in June 2012 after being released by the Indians.
As shown on MLBTR's DFA Tracker, Ambriz joins nine other players in DFA limbo. The Astros have 10 days to trade Ambriz, release him or outright him to the minors.
