Carlos Pena hit a two-run, seventh-inning homer 5, in the rubber match of game series.

Pena added a sac fly, Darwin Barney went 3-for-5 and scored a pair and Tyler Colvin had a two-run single for the Cubs, winners of 11 of their last 14.

John Grabow (3-0) earned the win despite allowing a run in the sixth and Carlos Marmol worked around a Michael Bourn walk to record his 28th save of the season.

Dan Uggla went 0-for-3 with a sac fly to see his career-best, 33-game hit streak come to an end.

Bourn went 3-for-4 with two RBI and a run scored for the Braves, who lost the final two games of the series after reeling off five straight victories.

Eric O'Flaherty (1-4) surrendered Pena's home run to suffer the loss.
