The Astros recalled Delgado from Triple-A Sugar Land on Sunday, Matt Kawahara of the Houston Chronicle reports.
Delgado will give the Astros some extra depth in the infield for Sunday's regular-season finale. He's appeared in 19 games for the Astros this season, going 9-for-37 (.243) with one home run and four RBI in the majors. Ronel Blanco was optioned to the minors in a corresponding move.
