Bracho was recalled from Triple-A Reno on Thursday, Nick Piecoro of The Arizona Republic reports.
Bracho was added to offer another arm out of the bullpen after the Diamondbacks deployed five relievers during Wednesday's 14-inning win over the Pirates. The 24-year-old compiled an impressive 1.62 ERA and 29 strikeouts in 16.2 innings with Triple-A Reno, but he's yet to find his groove with the big club; posting a career 6.18 ERA and 1.50 WHIP through 39.1 big-league innings.
