Braves 6, Nationals 4 (13): Evan Gattis singled home the go-ahead run in the 13th as visiting Atlanta survived blowing a two-run ninth-inning lead to move past Washington and into first place in the National League East.

Gattis, who finished 2-for-6 to extend his hitting streak to 19 games, drove home B.J. Upton - who drew a leadoff walk - with a base hit off Jerry Blevins (2-3). Ryan Buchter (1-0) pitched a scoreless 12th to get the victory in his major-league debut and Jordan Walden notched his second save as the Braves improved to 7-1 this season against their chief division rival.

Anthony Rendon hit a game-tying, two-run homer off Atlanta closer Craig Kimbrel with two outs in the bottom of the ninth that originally was ruled a double, but video review showed the ball clearly landed beyond the center-field fence. Ian Desmond also homered for the Nationals, who have lost six of their last eight to fall one-half game behind Atlanta.

Freddie Freeman, who finished with three hits and three runs scored, belted a solo homer in the first, but Desmond tied the game with a blast to left with two outs in the second. The Braves took the lead on Andrelton Simmons’ RBI single in the fourth, and Jason Heyward’s two-run double to right in the fifth made it 4-1.

Washington pulled within 4-2 when Denard Span tripled home Danny Espinosa with two outs in the seventh, and Kimbrel served up Rendon’s drive over the center-field wall on a 2-1 pitch in the ninth. Gattis steered a 0-1 offering into left field in the 13th to put the Braves ahead to stay, and Espinosa bobbled Simmons' potential double-play ball to allow Freeman to score an insurance run.
