MIAMI — Standing at second base during a replay review of his long drive, Miami Marlins slugger Giancarlo Stanton began chatting with Atlanta Braves second baseman Dan Uggla.
"He was bringing me negative energy," Stanton said. "He told me it was off the top" of the wall.
The replay determined Stanton had a home run, but plenty of negative energy stuck with the Marlins, who were swept in their new ballpark for the first time when they lost to Atlanta 8-2 Thursday.
The Marlins began the three-game series in a virtual tie for first place in the NL East, then were outscored by the Braves 21-3.
"They came in and whipped our butts," Stanton said. "It's not like we're going downhill from here. A little slip-up. Ain't no problem."
Stanton hit his 14th homer and Jose Reyes hit his first for the Marlins, but they went 0 for 13 with runners in scoring position and left 11 men on base. They totaled 16 hits in the series.
"We're in a little slump right now," pitcher Mark Buehrle said. "That's what happens when you face good teams and good pitching."
Buehrle (5-6), who had won his three previous career starts against Atlanta, allowed two runs and three hits in six innings. He took a one-hitter and a 1-0 lead into the sixth, but Michael Bourn singled with two out and Martin Prado hit a 2-2 pitch just inside the left-field foul pole for his fourth homer.
Prado added an RBI single in the eighth. Jason Heyward hit two solo homers to center, and Bourn tacked on a three-run homer in the ninth.
"Our bats came alive," Heyward said.
Mike Minor (3-4) needed 103 pitches to get through five innings but allowed only one run, and four relievers completed a nine-hitter.
The Braves, who have won six of their past seven games, earned their third road series sweep. Their 20-14 record in away games is the best in the NL.
Heyward homered onto the grass beyond the 418-foot sign with two out in the seventh. It was the first homer allowed by Steve Cishek in 24 2-3 innings this year.
Heyward connected again in the ninth for his second career multihomer game. Atlanta's four home runs were a season high.
Flashy glove work helped the Braves preserve a two-run lead in the seventh after a leadoff walk. Heyward made a sliding catch in right field to rob Omar Infante of a hit, and Andrelton Simmons followed with a diving backhand stop to start a 6-4-3 double play.
"For me the whole game was the seventh inning," Braves manager Fredi Gonzalez said. "It's a different game if we don't turn the double play."
Stanton's homer was originally ruled a double when the ball hit just inside the right-field foul pole and bounced back onto the field, but the call was reversed following a replay review.
The game was scoreless when Reyes homered leading off the fifth inning. The ball landed on top of the wall and bounced into the Marlins' bullpen.
That was the only run allowed by Minor. He walked five, allowed four hits and stranded seven to win for the first time in his past eight starts.
"He didn't buckle," Gonzalez said. "There was progress there. A couple of innings they could have put up some big numbers against him."
Minor walked two in the first inning and loaded the bases with two out, but Logan Morrison struck out. Morrison went 0 for 4 and is batting .133 with runners in scoring position.Comment on this story
