Uceta was recalled from Triple-A Reno to serve as the 29th man in Tuesday's doubleheader against the Dodgers, Sarah Wexler of MLB.com reports.
He last threw three innings Saturday at Triple-A, so he could be available to log a few innings in relief if either Zach Davies or Drey Jameson get chased in their starts. Uceta, 24, has a 5.04 ERA at Triple-A and a 5.82 ERA in the majors this season.
