Atlanta has won two straight following a season-high four-game losing streak. The Braves, who have 12 games left, maintained a 4 1/2-game wild-card lead over St. Louis.
Cristhian Martinez pitched a scoreless sixth and Eric O'Flaherty (2-4) a scoreless seventh as the two combined to face the minimum for Atlanta.
Five Braves combined on a four-hitter, and the Marlins didn't get a hit after the third or a runner after the fifth.
Cristhian Martinez, Eric O'Flaherty (2-4), Jonny Venters and rookie Craig Kimbrel each pitched a perfect inning, with Kimbrel striking out the side for his major league-leading 44th save in 49 chances.
O'Flaherty lowered his ERA two points to 1.05 ERA, best among major league relievers.
Greg Dobbs homered in the second off Randall Delgado, and Ricky Nolasco (10-11) held the lead until the seventh.
Dan Uggla walked with one out, and took third on Brian McCann's single, just the Braves' third hit. Prado squared as Nolasco released a pitch, and as the ball bounced softly inside the first-base line as Uggla scored without a play.
Gonzalez homered with two outs, his 13th of the year. Gonzalez went 2 for 3 and finished the series 8 for 11 (.727) with five RBIs against his former team.
