The Diamondbacks recalled Uceta from Triple-A Reno on Wednesday.
Uceta will provide some reinforcement in the bullpen for the Diamondbacks, who needed four pitchers to cover the final 6.1 innings of Tuesday's 14-8 loss to the Reds after starter Tyler Gilbert recorded only five outs before departing. Arizona demoted Gilbert to Triple-A to clear room on the active roster for Uceta.
