Ortega was optioned to Triple-A Salt Lake on Saturday.
Ortega had been with the team since Opening Day, recording a respectable 3.81 ERA in 26 innings of relief. He's struggled significantly over his last five outings, however, giving up 11 runs (seven earned) on 10 hits in five innings of work. Austin Warren (nose) was activated off the injured list to take his place in the bullpen.
