Bracho was optioned to Triple-A Reno on Saturday.
Bracho was brought up Thursday to serve as an extra bullpen arm, but didn't make any appearances during his short stint in the big leagues. He returns to Reno, where he has posted a dazzling 1.62 ERA and 29:6 K:BB over 14 relief appearances this season and converted three saves in four opportunities. Look for Bracho to be top candidate for another promotion should a bullpen spot open up in the future.
