BOSTON — Shane Bieber won for just the second time in six starts this season, allowing two runs and four hits over seven innings to lead the Guardians over the Red Sox 5-2 on Friday night.

Bieber (2-1) struck out four and walked two, getting his first victory since April 10. The righthander has made 26 consecutive starts of at least five innings.

“All together, it was a good start,” Bieber said after getting a first-inning lead. “Just trying to ride that wave and momentum and try to eat up innings and was able to do that.”

Cleveland got back to .500 at 13-13, winning consecutive games for the first time since April 14-15. The Guardians are 9-5 on the road.

“Other than hitting last, I don’t know if home and away is that big of a difference, especially early in the season when there’s not a lot of crowds and it’s not all that noisy,” Cleveland Manager Terry Francona said.

All-Star closer Emmanuel Clase gave up Jarren Duran’s leadoff double in the ninth before inducing three straight groundouts for his ninth save in 10 chances.

Duran became the first Boston player to hit three doubles in a game since Rob Refsnyder against Baltimore last Aug. 19. The Red Sox hit five doubles and none of those batters scored as Boston went 2 for 13 with runners in scoring position and lost for the third time in four games. The Red Sox dropped to 1-7 when not homering.

Pivetta (1-2) gave up four runs and five hits in five innings, his ERA rising to 5.11.

Josh Naylor’s sacrifice fly and Bell’s RBI double just over a leaping Duran in front of the Green Monster scoreboard opened a 2-0 first-inning lead.

“I should have had that ball honestly,” Duran said.

Myles Straw hit a run-scoring single in the second and Kiké Hernández’s RBI single cut the deficit to 3-1 in the bottom half.

Mike Zunino homered into the first row of the Green Monster seats in the fourth. He has 16 homers against Boston, four more than he has hit against any other team.

“He’s got a lot of experience playing in this park against this team and that’s what he can do. That’s why we brought him in here,” Bieber said of his catcher. “Obviously, he calls a great game, but his bat is important to us and will be going forward.”

Alex Verdugo hit a run-scoring groundout in the fifth. Boston had runners at the corners with one out in the eighth when Trevor Stephan struck out Rafael Devers and retired Triston Casas on a groundout.

Will Brennan homered off Kutter Crawford with two outs in the ninth, his second big league home run and first since last Oct. 2 against Kansas City’s Max Castillo.

This season, he has made six appearances with Triple-A Salt Lake, allowing four runs and six hits in 8 1/3 innings with a 4.32 ERA.
