Yainer Diaz sidelined with oblique strain

Manager Joe Espada didn't provide a specific timeline for Diaz's return, only that he'll be out "for a while." The Astros selected the contract of catcher César Salazar from Triple-A Sugar Land to serve as backup, with veteran Christian Vázquez stepping in as the starter. freshyourfeel.org

The 27-year-old Diaz is hitting .248 with two home runs and 14 RBIs in 26 games this season. In other moves, the Astros recalled right-hander Jason Alexander and outfielder Zach Dezenzo from Sugar Land, reinstated infielder Nick Allen from the IL, and designated outfielder Dustin Harris for assignment.
