With Friday night's 6-2 loss to the Phillies, the Braves were unable to take advantage of the Brewers' ninth-inning rally that doomed the Nationals. A win in Philadelphia would have moved them one game closer to the first-place Nationals, who lead the National League East by 5 1/2 games.
The Braves remain six games ahead of the Cardinals in the NL Wild Card standings. The top two teams will meet in a one-game playoff to determine which advances to the Division Series. Atlanta's magic number to clinch a playoff berth also remained at five because of the streaking Brewers' comeback win.
"We've got enough stress going on, on the field," Braves first baseman Freddie Freeman said. "The last thing we need to worry about is whether Milwaukee is beating Washington tonight. We've got to take care of our business. If we don't take care of our business, it doesn't really matter what is going on behind us on the scoreboard."

A tiebreaker game will be played to determine a division winner, even if the tied clubs are assured of participating in the postseason. If a division championship tiebreaker is necessary, the head-to-head record between the clubs will determine home-field advantage. If the head-to-head record is tied, then the division record will be the next tiebreaker.
If two clubs are tied for the two Wild Card berths, home-field advantage will be determined by the head-to-head record between the clubs. If the head-to-head record is tied, then the division record will be the next tiebreaker.
