Alex Bregman hammered a go-ahead two-run homer to help the Boston Red Sox defeat the visiting Los Angeles Dodgers 4-3 Sunday.

Bregman’s 13th home run of the year came against Los Angeles starting pitcher Dustin May to conclude a three-run fifth inning.

Michael Conforto had three hits — a solo home run and two doubles — for the Dodgers, who also received two hits from Shohei Ohtani.

The Red Sox prevailed twice in the three-game series. Los Angeles won 5-2 Friday, and Boston earned a 4-2 victory Saturday.

Boston starter Walker Buehler pitched against the Dodgers — his former team — for the first time in his career, and was pulled with two outs in the fifth. Buehler gave up three runs on four hits, struck out four and walked five.

Brennan Bernardino (4-2) earned the win for recording the final out of the fifth.

Red Sox closer Aroldis Chapman left the game with one out in the eighth. He threw 11 pitches in the inning and walked two. Jordan Hicks got the final five outs for Boston for his second save.

May (6-7) pitched the first five innings for Los Angeles. He surrendered four runs on five hits and struck out five without a walk.

The Red Sox grabbed a 1-0 lead in the first inning when Roman Anthony was hit by a pitch, took third on Jarren Duran’s single and scored on Trevor Story’s sacrifice fly to center field. It was the second time the Red Sox have scored first in their nine games since the All-Star break.

Los Angeles made it a 1-1 game in the third. Miguel Rojas scored when Freddie Freeman drew a bases-loaded walk against Buehler.

The Dodgers led 2-1 after Conforto homered against Buehler leading off the fourth, and Mookie Betts drove in Rojas from second with an RBI single to make it 3-1 later in the inning.

Boston regained the lead by scoring three times in the fifth. It was 3-2 after Roman Anthony hit an RBI triple that drove in Abraham Toro, and Bregman followed with his two-run home run that put Boston in front.
