ATLANTA -- Julio Teheran's ability to work through trouble impressed manager Fredi Gonzalez, who said it's more proof of the young right-hander's added maturity in his breakout season.
The Braves won two of three in the series and stretched their NL East lead over the second-place Nationals to 15 ½ games.
Both teams exhausted their bullpens in the Nationals' 8-7 win in 15 innings on Saturday night, making it important for the Braves that Teheran protect Atlanta's relievers as long as possible. The Nationals had two runners with no outs in each of the first three innings, putting a strain on Teheran's pitch count and making Gonzalez nervous in the Atlanta dugout.
"I'm thinking he's right at 60 pitches in three innings and you know your bullpen is spent," Gonzalez said. "You're thinking man, oh man. He did a nice job getting us through the sixth. Once he got us through six we were thinking we've got a shot here with the guys we have."
Four Atlanta relievers combined to preserve the win for Teheran (10-6).
The game ended when third base umpire Marvin Hudson ruled Harper went around on an attempted check swing.
It was another frustrating moment in a long season for the Nationals, who have lost three of four after five straight wins.
"I think in that situation you can't really call that," Harper said. "Especially when the home plate umpire says `No' about three times and doesn't want to check. They obviously check and they bang me. That's one less pitch I get to see against him.
"Kimbrel's a great closer. I think trying to see as many pitches as you can against him is huge. The deeper I get in the count makes me stronger."
Harper, who had two hits, said he didn't mind being booed before every at-bat during the series.
"I love these fans," Harper said. "These people, they're absolutely unbelievably amped up for their team."
Teheran had baserunners reach second in five of his six innings. He retired the Nationals in order only in the fourth.
Teheran gave up five hits with three walks as the Nationals stranded nine runners in his six innings.
"I know anytime I got in trouble like that I stay confident," Teheran said, adding he wanted to make it deeper in the game.
There was no sign of the tensions between the teams that began when both benches emptied after Teheran hit Harper in a Braves win at Washington on Aug. 6.
Braves pitchers hit Harper with two pitches in Atlanta's win on Friday night. Washington's Stephen Strasburg hit Justin Upton in the first inning on Saturday night and was ejected after throwing two straight pitches behind Andrelton Simmons' back.
There was no reaction from the umpires or the Nationals on Sunday when Teheran, who often pitches inside, hit Rendon to open the third. Teheran leads the National League with 13 hit batters.
"It's over with," Gonzalez said of the friction. "It's two boys playing in the sandlot in the schoolyard. It's over with. I think both teams have respect for each other, obviously. There are a lot of good players on that club and we've got good players and I don't see anything going on the rest of the (season)."
Harper followed with a single but Teheran pitched out of trouble.
The Braves scored twice in the first. B.J. Upton walked and stole second. Rookie second baseman Phil Gosselin, making his first start in the majors, reached on a bunt single for his first hit. Freeman and Johnson singled home runs.
