The Astros outrighted Biagini to Triple-A Round Rock on Wednesday, Chandler Rome of the Houston Chronicle reports.

Biagini went unclaimed off waivers after the Astros designated him for assignment last week ahead of their wild-card series with the Twins. The right-handed reliever will have the option of declining the outright assignment, which would allow him to hit free agency before the postseason concludes.
