BALTIMORE -- Matt Wieters homered leading off the 11th inning, and the Baltimore Orioles beat the Atlanta Braves 2-1 Monday night for their third straight victory.
Wieters hit a 1-0 pitch from Luis Avilan (2-4) over the center-field wall. It was Wieters' fourth home run, the first since June 25, and his teammates celebrated by dousing him with a bucket of water at the plate.
Brad Brach (4-2) worked the 11th for the Orioles, who hadn't won three in a row since late June.
Rookie Adonis Garcia homered for the Braves, who have dropped 11 of 15.
Garcia connected off All-Star reliever Zach Britton in the ninth inning to break up a scoreless duel, but Baltimore rallied in the bottom half against former Oriole Jim Johnson.
Playing in his fifth major league game, Garcia drove a 1-0 pitch over the right-field scoreboard. Garcia, a 30-year-old Cuban native, has two homers since making his debut on Saturday night.
Britton had allowed only one home run in 39 games before Garcia connected.
Looking for his 10th save, Johnson promptly gave up singles to Adam Jones and Wieters to put runners on the corners with no outs for J.J. Hardy, who delivered a sacrifice fly.
Earlier, both starting pitchers were dominant.
Baltimore's Kevin Gausman was working on a four-hitter before a pair of two-out singles in the eighth inning put runners at the corners with two outs. Left-hander Brian Matusz entered to face left-handed hitter Freddie Freeman, who struck out on four pitches.
Gausman walked one and struck out five over a career-high 7 2-3 innings.
Alex Wood allowed three hits and two walks in 7 1-3 innings. The right-hander was replaced by Jason Frasor, who struck out Manny Machado on a 3-2 pitch with two on and two outs.
Former Oriole Nick Markakis returned to Baltimore for the first time since signing a four-year, $44 million contract with Atlanta during the offseason. Many in the crowd of 26,256 acknowledged his nine-year run with the Orioles with a lengthy standing ovation before he stepped into the batter's box to begin the game.
Markakis went 2 for 5 and made five putouts in his familiar post in right field.
