MILWAUKEE (AP) – Brian McCann hit a grand slam and the Atlanta Braves got solo home runs from Chris Johnson and Jordan Schafer in a 7-4 victory over the Milwaukee Brewers on Sunday.  Beaten 2-0 by the Brewers on Friday and Saturday, the Braves entered the game scoreless in 24 consecutive innings. The streak came to a quick end when McCann smacked a two-out slam to left-center in the first inning off Alfredo Figaro.   Johnson led off the second with an opposite-field homer to right field. A leadoff shot by Schafer in the fourth extended the lead to 6-0.  Schafer had four hits in five at-bats, including a double. McCann also reached base safely four times in five trips to the plate.
