TORONTO — J.D. Martinez drove in the tiebreaking run when he was hit by a pitch with the bases loaded in the 10th inning, Alex Verdugo added a two-run double, and the Boston Red Sox held on to beat the Toronto Blue Jays 6-5 on Wednesday, avoiding a three-game sweep.

Verdugo also hit a two-run homer and had four RBI, and Franchy Cordero had four hits as Boston won for the third time in 10 meetings with Toronto this season.

With automatic runner Jackie Bradley Jr. at second base to start the 10th, Blue Jays right-hander David Phleps (0-2) walked Rob Refsnyder and Rafael Devers to load the bases for Martinez, who was hitless in his previous 13 at bats.

Bradley scored when Phelps hit Martinez in the back with a 1-2 pitch. Tim Mayza came on and got Xander Bogaerts to ground into a double play, but Verdugo followed with a two-run double to make it 6-3.

Matt Strahm (3-2) struck out Bo Bichette and Guerrero in the ninth, but gave up an RBI single to Santiago Espinal and an RBI double to Cavan Biggio in the 10th. Strahm ended it by getting George Springer to fly out.

Both benches and both bullpens cleared after Red Sox right-hander Nick Pivetta hit Blue Jays catcher Alejandro Kirk on the left elbow in the third. After Toronto Manager Charlie Montoyo left the dugout, Blue Jays slugger Vladimir Guerrero Jr. hopped the dugout fence and started yelling at Pivetta, who yelled back. Devers stepped in front of Guerrero as other players rushed to join the melee, but no punches were thrown.

Springer hit his 15th home run for the Blue Jays, a solo shot in the fifth.

Toronto opened the scoring on Espinal’s two-out RBI single in the second, but Boston answered in the third on Refsnyder’s sacrifice fly, a drive to deep center that Springer ran down.

Springer put the Blue Jays in front with his leadoff blast in the fifth but the Red Sox reclaimed the lead in the sixth. Bogaerts reached on a two-out infield single and Verdugo followed with a drive to right, his sixth.

The Blue Jays tied it against Ryan Brasier in the eighth, rallying against Boston’s bullpen for the second straight night. Lourdes Gurriel Jr. hit a one-out double and was replaced by pinch-runner Bradley Zimmer, who scored when Raimel Tapia followed with a double to center. The blown save was Boston’s 16th in 33 chances.

Pivetta allowed two runs and five hits in six-plus innings. He walked three and struck out five.

Blue Jays right-hander Alek Manoah allowed three runs, two earned, and six hits in seven innings. He walked one and struck out six.

TRAINER’S ROOM

Red Sox: Right-hander Garrett Whitlock (right hip) threw a bullpen session before the game, his second in three days. Manager Alex Cora said Whitlock could return in a relief role when he is activated.

SEE YOU IN SEPTEMBER?

One day after his team blew a ninth-inning lead and lost 6-5, Cora said he was willing to bet his roster would be more complete when Boston comes back north of the border for a three-game series beginning Sept. 30. Boston closer Tanner Houck, who has six saves, has missed two trips to Toronto this season because he isn’t vaccinated against COVID-19. The vaccination status of injured left-hander Chris Sale is unclear.

ROSTER MOVES

Toronto completed the signing of right-hander Sergio Romo to a one-year deal. Right-hander Shaun Anderson was optioned to Triple-A Buffalo to make room on the major league roster, while left-hander Tayler Saucedo (right hip) was transferred to the 60-day IL to open a spot on the 40-man roster. Romo was cut by Seattle June 20.

Romo offered a wry assessment of his appeal to other big league teams after being cut by the Mariners.

“I’m 39 and throw 85,” Romo said.
