Atlanta Braves third baseman Paul Janish (4) prepares to tag out Washington Nationals right fielder Jayson Werth (28) on a steal attempt in the sixth inning of a a baseball game in Atlanta, Sunday, Aug. 18, 2013.

ATLANTA - Julio Teheran pitched around trouble through six scoreless innings and a tired Atlanta bullpen held on as the Braves beat the Washington Nationals 2-1 on Sunday.

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.

Four Atlanta relievers made it through the final three innings, preserving the win for Teheran (10-6).

Craig Kimbrel pitched the ninth for his 39th save. After Denard Span reached on an infield hit, Kimbrel struck out Anthony Rendon and Bryce Harper to end the game.

Freddie Freeman and Chris Johnson hit RBI singles off Gio Gonzalez (7-6) in the first. Gonzalez gave up only two hits and no runs in the next six innings.

Teheran had baserunners reach second in five of his six innings. He retired the Nationals in order only in the fourth.

The right-hander gave up five hits with three walks as the Nationals stranded nine runners in his six innings.

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.

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.

The Nationals broke through for a seventh-inning run off Scott Downs and David Carpenter, with Jayson Werth hitting an RBI single.
