ATLANTA -- Adam LaRoche hit a solo home run in the 15th inning to give the Washington Nationals an 8-7 win over the Atlanta Braves Saturday.
LaRoche fouled off three pitches before he yanked a 1-and-2 curveball from Kris Medlen (10-11) into the right field stands for his team-leading 18th homer
The win was the sixth in the last eight games for the Nationals, who improved to 5-9 in extra-inning games. Atlanta is now 10-5 in extra innings and lost for only the third time in its last 20 games.
Atlanta's Jason Heyward sent the game to extra innings with a two-run homer with two outs in the ninth inning off closer Rafael Soriano. It was Heyward's 13th homer and his second of the game.
The winner pitcher was Craig Stammen (6-5), who struck out five in three scoreless innings. Dan Haren earned his first save by throwing a scoreless 15th in his first relief appearance of the year.
The game featured the second-inning ejection of Washington starter Stephen Strasburg for intentionally throwing at two Atlanta hitters.
With tensions already high after Washington centerfielder Bryce Harper had been hit by a pitch twice on Friday, Strasburg plunked Justin Upton on the rear end in the first inning. Upton had won the game on a tenth-inning homer on Friday. Strasburg's pitch drew a warning from umpire Marvin Hudson.
Strasburg was ejected in the second inning after throwing three consecutive wild pitches, the last two well behind the back of batter of Andrelton Simmons. Hudson ejected Strasburg and manager Davey Johnson. Strasburg showed no emotion as he walked off the field.
The Braves also got a two-run homer from Brian McCann, his 18th, and a solo homer from Freddie Freeman, his 15th, as they erased a 6-2 lead. Ryan Zimmerman hit his 14th home run for Washington.
The Nationals jumped out to a 2-0 lead in the first inning with Wilson Ramos driving home a pair with a two-out base-loaded single.
The Braves got one back in the bottom of the first. Heyward hit a 3-and-2 pitch into the stands in right-center field for his 12th homer, his second as a leadoff hitter.
Washington stretched its lead to 4-1 with two runs in the second. Jayson Werth slapped a two-out single into left to drive home a pair and chase Minor.
Atlanta scored again in the bottom of the inning. Jordan Schafer walked and scored on three wild pitches. The final two pitches were thrown well behind the back of Andrelton Simmons, causing umpire Marvin Hudson to eject Strasburg, who had been issued a warning after he plunked Justin Upton on the backside in the first inning.
A two-out double by Roark put Washington ahead 5-2 in the fifth. It was the first career RBI for the rookie pitcher.
