SANDY SPRINGS, Ga. (Interstat) — Willson Contreras hit a two-run homer in the eighth inning Saturday night, lifting the Boston Red Sox to a 3-2 victory over the Atlanta Braves at Truist Park before a crowd of 39,336.

The game lasted 2 hours, 6 minutes.

Boston improved to 19-26 while Atlanta fell to 31-15.

Contreras’ blast came with two outs in the top of the eighth, after Wilyer Abreu had doubled. It erased a 2-1 deficit and gave Boston its first lead of the night. Red Sox starter Payton Tolle earned his second win against two losses, allowing two runs on four hits over six innings while striking out three and walking two. Aroldis Chapman recorded his 10th save, striking out one and walking two in a scoreless ninth that included a bases-loaded escape.

Atlanta starter Bryce Elder took the loss despite a strong outing. He allowed three runs on seven hits over eight innings, striking out three and walking none. Elder fell to 4-2.

Drake Baldwin drove in both Braves runs, homering in the first inning and singling home José Azócar in the fifth. Azócar finished with two hits, both doubles. Baldwin went 2 for 3 with the home run and two RBIs.

Boston scored its first run in the fourth. Mickey Gasper singled, Wilyer Abreu singled, and Contreras reached on a fielder’s choice that loaded the bases after an error by third baseman Austin Riley. Masataka Yoshida then lifted a sacrifice fly to left field, scoring Gasper and tying the game 1-1.

Atlanta answered in the fifth. Azócar doubled with one out, and Baldwin followed with a sharp single to left. Azócar scored, but Baldwin was thrown out trying to advance to second on the throw home, ending the inning with Atlanta ahead 2-1.

The Red Sox threatened in the seventh when Ceddanne Rafaela doubled with one out, but Elder retired the next three batters to preserve the lead.

In the eighth, Abreu doubled to left field with two outs, bringing Contreras to the plate. Contreras drove a 2-1 pitch to left-center for his ninth home run of the season, putting Boston ahead 3-2.

Chapman entered for the bottom of the ninth and immediately encountered trouble. Ozzie Albies popped out, Matt Olson lined out, but Austin Riley reached on a throwing error by shortstop Andruw Monasterio. Mauricio Dubón walked and Michael Harris II walked to load the bases. Chapman then got Ha-Seong Kim to ground out to first, ending the game.

Several Atlanta regulars struggled at the plate. Riley went 0 for 4, Michael Harris II went 0 for 3, Mauricio Dubón went 0 for 3, Matt Olson went 0 for 4, Ozzie Albies went 0 for 4, and Ha-Seong Kim went 0 for 4. Martín Pérez pitched a scoreless inning of relief for the Braves.

Jarren Duran doubled to lead off the game for Boston but was left stranded. Duran finished 1 for 4 with a double. Rafaela doubled for Boston in the seventh and finished 1 for 4. Contreras had two hits, including the homer, and drove in two. Abreu had two hits, including a double, and scored twice.

The victory snapped a two-game losing streak for Boston, which had lost 3-2 in 10 innings to Atlanta on Friday night. The Red Sox had dropped four of their previous six games heading into Saturday.

Atlanta had won four of its previous five games before Saturday’s loss.

The teams close their three-game series Sunday afternoon, then Boston travels to Kansas City for a three-game set beginning Monday. Atlanta goes to Miami for a four-game series starting Monday.

The game also featured strong defensive plays. In the fifth, left fielder Duran threw out Baldwin at second base after the single to left, a key out that prevented further damage. In the third, Boston turned a 4-6-3 double play to end a threat.

Boston’s pitching held Atlanta to four hits, with Tolle allowing only the two runs on four hits. Reliever Chapman allowed two walks but escaped the ninth without allowing a run.

The win was Boston’s third in its last seven games. Atlanta lost for just the fourth time in its last 11 contests.
