Burnes was recalled from Triple-A Colorado Springs prior to Sunday's game against the Braves.
Burnes shifted to a bullpen role with the Sky Sox in mid-June, and it didn't take long for the Brewers to bring him to the majors. The 23-year-old has a 5.15 ERA and 1.45 WHIP over 78.2 innings at hitter-friendly Colorado Springs, but he features a respectable 3.69 ERA and 1.19 WHIP on the road this season.
