The Astros recalled Murray from Triple-A Sugar Land on Monday, Matt Kawahara of the Houston Chronicle reports.
It will be the fourth stint in the big leagues this season for Murray, who has not fared well in his first three outings with the Astros, holding a 7.15 ERA and 5:7 K:BB across 11.1 frames. Murray will give manager Joe Espada a fresh option in the bullpen.
