MIAMI — The sliding Atlanta Braves stumbled again Monday night, losing 6-5 to the Florida Marlins on Omar Infante's game-ending two-run homer.
Atlanta now has dropped three of four, and its NL wild-card lead is down to 2½ games over surging St. Louis, which beat Roy Halladay and the Phillies 4-3 in Philadelphia. The Braves have eight games remaining, the Cardinals nine.
Rookie closer Craig Kimbrel came in to preserve Atlanta's 5-4 lead and retired the first two batters he faced in the ninth. But Emilio Bonifacio then hit a chopper to third baseman Chipper Jones, who could not field the infield hit.
Infante then drove a 1-0 pitch to deep left for his first game-ending homer. Infante's sixth homer of the season came against his former team and handed Kimbrel (4-3) his seventh blown save opportunity in 52 chances.
Dan Uggla and Jason Heyward homered for Atlanta, which scored four runs in the seventh to take the lead. Second baseman Infante had a costly error in the inning, which allowed the Braves to score the tiebreaking run.
Mike Stanton homered twice for the Marlins, and Logan Morrison added a two-run shot. Clay Hensley (6-6) pitched two scoreless innings to get the win.
Braves starter Mike Minor allowed four runs and six hits in 5 2-3 innings. He struck out six and walked two.
Stanton hit a solo shot into the upper deck in left in the first inning, then belted another solo shot in the third for his 34th of the season, tying Miguel Cabrera for second place on the Marlins' single-season list.
The 21-year-old Stanton has two multihomer games this season and four in his career. He also hit a pair at Chicago on July 16.
Ricky Nolasco retired the first 12 batters he faced before Uggla singled leading off the fifth. He allowed five runs, four earned, and five hits in 6 2-3 innings.
