Jarren Duran delivered a tiebreaking RBI single in the bottom of the eighth inning to help the Boston Red Sox avoid a three-game sweep with a 2-1 victory over the visiting Milwaukee Brewers on Sunday.

After Ceddanne Rafaela led off the inning with a double, Duran singled against reliever Elvis Peguero (4-2) on the next pitch.

Kenley Jansen pitched a 1-2-3 ninth to earn his ninth save of the season. Justin Slaten (3-2) got the win by striking out the side in the eighth.

The victory came after Milwaukee prevailed 7-2 on Friday and 6-3 on Saturday. It improved Boston's record to 9-0 on Sundays.

After the top of the seventh, Red Sox reliever Chris Martin and Brewers first base coach Quintin Berry got into a heated discussion, causing the benches and bullpen to spill out onto the field near first base. No punches were thrown and no ejections occurred.

Wilyer Abreu collected three of Boston's nine hits and scored a run. Rafaela went 2-for-3.

Gary Sanchez had a single and a double and was the only Milwaukee player with more than one hit. The Brewers struck out 12 times.

Boston received a strong start from Tanner Houck, who limited the Brewers to one run on seven hits in six innings. Houck recorded seven strikeouts and walked one.

Milwaukee starting pitcher Tobias Myers allowed a run on six hits in 4 1/3 innings. He struck out four and didn't walk a batter.

The Red Sox opened the scoring in the fourth. Abreu led off with a triple and scored when Rafael Devers hit a sacrifice fly to right field.

Milwaukee tied the game at 1 in the fifth when Oliver Dunn singled, stole second and scored on a William Contreras single to center.

Boston outfielder Tyler O'Neill, who left Saturday's game with a sore knee, did not play Sunday.

It was the finale of a nine-game road trip for Milwaukee, which went 4-5 during the trek.
