Bracho was recalled from Triple-A Reno on Monday.
Bracho will take the place of Jake Barrett on the roster and in the bullpen. Aside from a couple of rough outings earlier in the year, Bracho has been solid for the big club. In seven appearances (eight innings) since the beginning of June, the 25-year-old owns a shiny 1.13 ERA and 6:2 K:BB.
