Cravy was recalled from Triple-A Colorado Springs on Saturday.
Cravy will take the roster spot of Paolo Espino, who was optioned to Triple-A in a corresponding move. The 27-year-old held a 4.26 ERA and 1.37 WHIP through 19 innings (14 appearances) with Colorado Springs before earning the promotion. He'll offer the Brewers an extra bullpen arm for the time being, though his time with the big club could be short-lived with Junior Guerra (calf) expected to return to the Brewers soon.
