The Houston Astros are down a pitcher after right-hander Christian Roa was claimed off waivers by the Minnesota Twins ahead of Houston's series against the New York Yankees.

The Twins claimed a righty who made seven appearances with the Astros this season before being DFA'd.

The Astros have placed OF Taylor Trammell on the 10-day IL due to a left groin strain. To take his place on the active roster, the Astros selected OF Daniel Johnson (#31) to the Major League roster. To make room for Johnson on the 40-man roster, the Astros designated RHP Christian Roa for assignment.
