TORONTO — Rafael Devers joined an exclusive club of young Red Sox sluggers who have homered in three straight games, Michael Chavis hit a tiebreaking homer in the 13th inning, and Boston beat the Toronto Blue Jays 6-5 on Wednesday night.

Devers led off the eighth with a blast to left off Derek Law, his sixth. It made Devers the sixth player in Red Sox history aged 22 or younger to homer in three straight games. The others are Ted Williams, Babe Ruth, Carl Yastrzemski, Rico Petrocelli, and Jim Tabor.

But Marcus Walden couldn’t hold a 4-3 lead for Boston in the ninth. Brandon Drury hit a one-out double and pinch-hitter Danny Jansen sent the game to extra innings with a two-out single.

Toronto used two singles and an intentional walk to load the bases against Walden with one out in the 10th. Red Sox Manager Alex Cora brought Mookie Betts in to play as a fifth infielder before Walden fanned Freddy Galvis for the second out. After Betts returned to right field, Walden escaped the jam by getting Drury to fly out.

Betts put Boston back on top by connecting off Joe Biagini in the 12th, his eighth, but Rowdy Tellez tied it again with a two-out drive off Heath Hembree in the bottom half.

Chavis restored Boston’s lead with a homer off Jimmy Cordero (0-1), making Hembree (1-0) the winner. Chavis has 10 homers and 25 RBI in 28 games.

According to the team, the last time the Red Sox hit multiple go-ahead home runs in extra innings of the same game was April 29, 1951, at Philadelphia, when Dom DiMaggio and Tom Wright did it in the 11th and 12th innings.

Cordero, who was claimed off waivers from Washington on May 15, was making his Blue Jays debut.

Toronto has not won back-to-back games since a three-game sweep of Oakland from April 26-28. The Blue Jays are 6-15 since.

Mitch Moreland had two RBI and Jackie Bradley Jr. scored twice for the Red Sox, who have won three of four.

Toronto rookie Vladimir Guerrero Jr. hit his first home run at Rogers Centre, but that was all the Blue Jays got against Red Sox right-hander Rick Porcello, who allowed three hits in six innings.

All five of Guerrero’s home runs have come within the past eight days.

Toronto right-hander Aaron Sanchez was forced to leave after three innings because of a blister in his previous start, May 17 against the White Sox, but it didn’t seem to bother him against Boston. He allowed two runs and four hits in six innings. Sanchez is winless in five starts.

Red Sox slugger J.D. Martinez was held out of the lineup because of a sore back. Martinez sat out the previous two games because of illness, but had been expected to return Wednesday. The two-time All-Star is hitting .308 with nine homers and 28 RBI.
