Highlighted by consecutive home games in the 7th inning, played by Dansby Swanson and Jorge Soler, who hit the pinch, the Braves defeated the visiting Astros 3-2 and took a 3-1 lead.
Atlanta can catch the crown in front of a home crowd on Sunday night.
“I just want to win tomorrow. I don’t know how confident I am,” Braves coach Brian Snitker said when asked how he feels about the 3-1 advantage.
“I’m glad we are, quite honestly. I’d rather be three up than three lower, I guess. But I’ve been here too long to be in front of me.”
Houston had most of the momentum in the early substitutions of the game, but failed to seize the opportunity to score.
Astros stranded 11 baserunners and his shots were 0-for-8 and the runners were in a scoring position.
Atlanta rookie Dylan Lee recorded just one outing and handed the ball to Kyle Wright with loaded bases in the first inning.
But Wright allowed only one of his inherited runners to cross and gave the Braves a solid 4.2 work shifts to make it easier.
Jose Altuve’s solo shot in the fourth inning was Wright’s only major mistake, as Houston held a small 2-0 lead in five innings.
The star’s third player, Austin Riley, ranked Bravese on board at 6th with the single RBI on the left. The 24-year-old also played a key defensive game in the second inning, robbing Altuve of RBI on a heavily sinking line.
After Swanson and Soler played in the 7th, Altuve fell victim to the Braves ’defense again when left-back Eddie Rosario escaped to the warning lane at the top of the 8th, thus maintaining Atlanta’s 3-2 lead.
Brave closer Will Smith offered a complete 9th substitution, forcing Yordan Alvarez to surrender to first-team footballer Freddie Freeman in the playoffs of the night.
Atlanta reliever Tyler Matzek earned the Braves ’victory, while Houston’s Cristian Javier, who allowed both Swanson and Soler’s homers, lost.
“They played hard with us. They played very hard. We have to win tomorrow,” Astrosa manager Dusty Baker said.
“We’ve been facing the wall before so our guys know what to do. There’s not much to say. We know what we have to do. We have to win tomorrow.”
Former President Donald Trump was present at the 4th game and took part in the controversial “Tomahawk chop” on Saturday.
The passage – a stadium-wide uphill and a long tradition at the Braves Games – was once again under scrutiny as part of a national debate on racism and racial imagery in professional sports.
Several advocacy groups and observers have accused the chanting of mocking Indian groups and calling it racist. But many Braves fans, including Republican Gov. Gov. Brian Kemp, rejected the criticism, and the stadium encouraged fans to shout in the 3rd and 4th games of the series.
