Rafael Devers’ leadoff home run in the bottom of the ninth inning helped the Boston Red Sox come back from five runs down to beat the visiting Atlanta Braves 7-6 on Saturday night.

After Boston’s Aroldis Chapman (3-2) worked around two baserunners to strike out the side in the top half of the ninth, Devers — who finished 3-for-4 with a double, two RBI and two runs scored — clubbed a 2-1 curveball into the right-center field bullpen off Pierce Johnson (1-1) for his first career walk-off homer.

Designated hitter Devers finished 3-for-4 with a double, two RBIs and two runs scored as the Red Sox won the second of a three-game series.

Boston had scored twice and tallied three hits in both the seventh and eighth innings. Jarren Duran finished with four RBIs, including two on a game-tying single to right with two outs in the eighth.

In the seventh, Ceddanne Rafaela’s leadoff double down the left-field line began a stretch of three Boston hits in four batters to cut its deficit to 6-4. Devers’ opposite-field single and Alex Bregman’s wall-ball double plated runs.

Consecutive one-out hits by Abraham Toro (double) and Carlos Narvaez (single) set up Duran’s game-tying knock an inning later.

Matt Olson and Marcell Ozuna hit back-to-back homers in the first and Drake Baldwin added a two-run shot in the third for a 5-0 advantage for Atlanta, which was held scoreless after the fourth against four relief pitchers.

The Braves wasted little time getting to Boston starter Lucas Giolito as Austin Riley drew a one-out walk and scored on Olson’s two-run homer out to the bullpen in center in the first inning. Ozuna made it back-to-back jacks and a 3-0 Atlanta lead in the next at-bat, depositing a line-drive solo shot to deep left and completely out of the ballpark.

Another one-out walk helped Atlanta extend its lead to 5-0 in the third. After Ozuna drew a free pass, Baldwin hit a towering two-run homer inside Pesky’s Pole in right that was upheld on review.

Braves starter Grant Holmes set aside the first seven Red Sox he faced before a one-out walk to Narvaez in the third. Duran’s two-run homer to straightaway center got Boston on the board two batters later.

The Atlanta starter limited the hosts’ damage to two third-inning runs, inducing an inning-ending fly ball after allowing a Devers double and walking Bregman.

In the fourth, the Braves got a run back on Riley’s two-out single that dropped into shallow left. Eli White hit a leadoff single and stole second to help set up the RBI opportunity and a 6-2 lead.
