The Astros are expected to recall Salazar from Triple-A Sugar Land on Tuesday, Ari Alexander of KPRC 2 in Houston reports.
Yainer Diaz was hit in the right hand by a foul tip during Sunday's loss to the Angels. He was able to stay in the game, but Salazar's impending addition to the roster could indicate that Diaz will have to miss some time. The Astros should offer more clarity later Tuesday.
