The Diamondbacks optioned Uceta to Triple-A Reno on Sunday.
Uceta was sent out to Triple-A in order for the Diamondbacks to add a fresh arm -- Luis Frias, who was recalled from Reno -- to the bullpen ahead of Sunday's series finale with the Cardinals after five relievers were needed to record the final 11 outs of Saturday's 16-7 loss. One of those relievers was Uceta, who was lit up for four earned runs on three hits and one walk during his one inning out of the bullpen.
