The Astros recalled Salazar from Triple-A Sugar Land on Tuesday.
Salazar will rejoin the big-league squad to provide the Astros with an additional bench bat as Ben Gamel (fibula) moves to the injured list. Salazar has gone 7-for-23 with eight RBI through 10 games in the majors, but he may struggle to receive playing time while serving as Houston's No. 3 catcher.
