Bracho was recalled from Triple-A Reno on Sunday.
With Chris Iannetta (concussion) being placed on the 7-day disabled list, the Diamondbacks decided to add another arm to their bullpen. Bracho has been solid at Reno this season, as he's allowed just three runs over 13.2 innings (11 games) and struck out 24 batters in that time. However, he's yet to find his groove in the show, as he owns a 5.87 ERA and 1.49 WHIP for his major-league career.
