The Diamondbacks optioned Uceta to Triple-A Reno on Wednesday.
Arizona opted to move Uceta to the minors since he was unlikely to be available for the next couple of days after tossing three innings and 47 pitches in a mop-up role during the Diamondbacks' 12-3 loss to the Dodgers on Tuesday in the second game of a doubleheader. Carlos Frias was summoned from Triple-A to fill Uceta's spot in the bullpen.
