"You mean it has been seven years?" Wolf asked.
At least the left-hander doesn't have to keep track of the drought any longer.
Wolf (7-8) allowed seven hits and three runs in six innings for his first win over the Braves since Sept. 9, 2003, with Philadelphia -- also at Turner Field. He improved to 5-12 in his career against Atlanta.
"They put pressure on us all night," Wolf said. "That's why it's so gratifying to pitch well against this team, especially considering my history of not being a Cy Young against them."
Wolf outlasted Tommy Hanson (8-6), who gave up six hits and four runs, three earned, in five innings.
Atlanta's Chipper Jones sustained a mild left hamstring strain on a seventh-inning swing. He grabbed the back of his leg after the swing and left the game after hitting a popup with the bases loaded to Rickie Weeks at second base.
Jones said he has a 50 percent chance of playing on Saturday.
"It's nothing major," he said. "It's just a precautionary measure right now."
The team said Jones is day to day.
Jones, who was 0 for 3 with a walk, said Wolf, like Milwaukee's Dave Bush, is tough with his slow curveballs.
"He kept the guys off balance," Jones said. "Those guys know what they're doing with it. It just goes to show you don't have to throw 95 [mph] to be effective in this league as long as you change speeds and locate."
The Braves scored only one run in the seventh, when Wolf left the game.
Hanson pitched scoreless fourth and fifth innings before he was removed for a pinch-hitter in the bottom of the fifth.
"I wish I could have found it sooner and given us a better chance to stay in the ballgame and not give them that lead early," Hanson said.
Casey McGehee had three hits, including a run-scoring single in the eighth.
The Braves began the night five games ahead of the second-place Mets in the NL East.
Alcides Escobar and Wolf drove in runs in the second before Braun's two-run homer in the third pushed the lead to 4-0.
The Brewers added two runs in the sixth off Kris Medlen. Atlanta manager Bobby Cox said before the game Medlen still is the Braves' No. 5 starter, but an off day on Monday gives the right-hander a chance to stay sharp while pitching in relief.
Medlen gave up three hits and two runs. Only one run, on Weeks' run-scoring single, was earned. First baseman Troy Glaus was charged with an error when he couldn't handle a low throw from new shortstop Alex Gonzalez on a single by Hart, allowing George Kottaras to score.
Gonzalez, acquired in an All-Star break trade that sent Yunel Escobar to Toronto, went 1 for 3 and scored a run.
Jason Heyward had a single in the fourth to snap an 0-for-16 drought. Heyward scored on a double by Glaus.
