The move was made in order to activate Cristian Javier (shoulder) from the 60-day injured list. Sousa hasn't pitched since May 4 and this doesn't alter his timeline, as he's still expected to rejoin the Houston bullpen following the All-Star break in a couple weeks. He's working his way back from elbow inflammation.

Sousa has been limited to only five appearances for the Astros this season, first missing time due to an oblique strain and more recently battling left elbow inflammation. He's been shelved for nearly two months but appears close to throwing in a game. Sousa appears unlikely to join the Astros' active roster before the All-Star break.
