As the only team appearing to have any chance of catching the runaway Phillies in the NL East, the Atlanta Braves just keep finding ways to win.
Freeman is batting a solid .272, with 11 homers and 38 RBI, though his pace of production has picked up of late. He's homered four times and driven in 11 runs in his past 10 games.
While the Braves may never catch the Phillies, they don't have to worry much about the rest of the division. The Marlins have fallen apart and they are 6 1/2 and 7 games in front of the Mets and Nationals, respectively.
The Braves lead the wild card standings by four games over Arizona and five better than the Milwaukee Brewers.
