The Astros designated Barrosa for assignment Saturday, Matt Kawahara of the Houston Chronicle reports.
After being claimed off waivers from Arizona on Sept. 6, Barrosa went 1-for-7 with two walks while appearing in four games for the Astros. He'll now be DFA'd for the second time in three weeks to create room on Houston's 40-man roster for Brice Matthews (knee), who returned from the 60-day IL on Saturday.
