Jose de Jesus Ortiz of the Houston Chronicle reports that the Astros have placed closer Luke Gregerson on the family emergency medical list. To take his place on the roster, the Astros promoted Asher Wojciechowski from Triple-A Fresno. Chad Qualls will serve as the Astros’ interim closer.
Gregerson, 30, has converted seven saves in eight opportunities with a 2.57 ERA and an 11/2 K/BB ratio in 14 innings. He signed with the Astros on a three-year, $18.5 million contract as a free agent back in December.
Wojciechowski, 26, allowed 13 runs on 23 hits and seven walks with 16 strikeouts in 16 innings over three starts and one relief appearance.
