TORONTO — British Columbia native Ryan Dempster allowed one run in six innings to earn the win in his first career start in Toronto as the Boston Red Sox defeated the Blue Jays 3-1 on Thursday.

The Red Sox (20-8) won the final two games of the three-game series and have won four of six meetings with the Blue Jays (10-19) this season.

Dempster (2-2) of Sechelt, British Columbia, allowed four hits, including a home run to Brett Lawrie of Langley, British Columbia, and walked three while striking out four before a crowd of 25,851 at Rogers Centre.

Joel Hanrahan pitched the ninth for his fourth save despite giving up the third single of the game for Colby Rasmus.

Left-hander J.A. Happ (2-2) took the loss.

Left-hander Andrew Miller took over for Dempster to start the seventh and allowed a single by Rasmus and a walk to Munenori Kawasaki. Junichi Tazawa took over and walked Lawrie to load the bases with two out before striking out Adam Lind.

The Red Sox scored twice in the second to take a 2-1 lead and moved into a 3-1 lead in the sixth when right-handed reliever Brad Lincoln walked David Ross who took second when Stephen Drew struck out on a wild pitch. Jacoby Ellsbury greeted Steve Delabar with a looping singled to left to score the run.

Toronto starter J.A. Happ allowed two runs, three hits and seven walks in 3 2/3 innings before Brad Lincoln replaced him to get the final out of the fourth with the bases loaded.

The Blue Jays took the lead when Lawrie led off the home first with his first home run of the season.

The Red Sox came back with two in the second that started with a double by Mike Napoli. After a walk to Will Middlebrooks, Mike Carp singled in a run. A walk to David Ross loaded the bases and Stephen Drew hit a sacrifice fly.

The Blue Jays loaded the bases with one out in the third on three walks but Edwin Encarnacion hit into a double play.

Earlier Thursday, the success of Red Sox starter Clay Buchholz was questioned by two former MLB pitchers. Buchholz earned his sixth straight win to open the season on Wednesday.

Dirk Hayhurst, a former pitcher who is now an analyst for the Toronto Blue Jays, tweeted after Wednesday’s game against the Red Sox that he “saw video of Buchholz loading the ball with some Eddie Harris worthy slick’em painted up his left forearm.” Hayhurst told Toronto radio station Sportsnet 590 The Fan on Thursday that Buchholz was “absolutely” cheating during Wednesday’s start against Toronto.

Former Blue Jays ace Jack Morris saw the video for himself and agreed.

“I found out because the guys on the video camera showed it to me right after the game,” he said. “I didn’t see it during the game. They showed it to me and said, ‘What do you think of this?’ and I said, ‘Well, he’s throwing a spitter. Cause that’s what it is.”

The Red Sox disputed the accusations on Thursday. Buchholz said that this is the first time he’s been accused of doctoring a baseball.

“I’m doing the same thing right now as I did in 2008, when I was sent down to Double-A,” Buchholz told ESPNBoston. “But I guess something’s got to be wrong, right?’”

“He’s got rosin on his arm,” said Red Sox manager John Farrell. “He’s not loading up, he’s got rosin on his arm. As soon as someone pitches well or does well, they’re cheating.”

Buchholz was named American League Pitcher of the Month on Thursday. In six starts this season, he’s 6-0 with a 1.01 ERA in 47 innings. He has 47 strikeouts and 16 walks.

NOTES: The Blue Jays put right-hander Josh Johnson (right triceps inflammation) on the disabled list Thursday retroactive to April 29 and Lincoln was recalled from Class-AAA Buffalo. … Left-hander Ricky Romero will be recalled from Class-A Dunedin to start Friday’s game against the Seattle Mariners’ Felix Hernandez (3-2, 1.90 ERA) in Johnson’s place and another roster move will be made to make room for him. … Red Sox right-fielder Shane Victorino (lower back tightness), who did not play in the previous six games, was not in the starting lineup Thursday but hoped to be able play Friday in the opener of a three-game series against the Rangers in Texas. … Left-hander Felix Doubront (3-0, 4.24 ERA) will start on Friday for Boston against Texas left-hander Derek Holland (1-2, 3.38 ERA).

Phillies 7, Marlins 2: Kyle Kendrick pitched seven strong innings and Domonic Brown went 3 for 4 with a homer and two RBIs on Thursday night as the Philadelphia Phillies beat the Miami Marlins 7-2.

Ryan Howard also homered for the Phillies, who have won four of their last six.

Kendrick (3-1), who shut out the New York Mets in his previous start, allowed two runs and seven hits. He struck out five and walked two. His ERA is now 2.43, best in a rotation that includes Cole Hamels, Cliff Lee and Roy Halladay.

Mike Adams and Jonathan Papelbon each worked a perfect inning in relief for Philadelphia.

Brown and Howard hit solo homers in the second and fourth, respectively. It was the fourth homer of the season for each.

Brown also had an RBI single in the Phillies’ two-run eighth.

Justin Ruggiano hit his fourth homer of the season for the Marlins, who dropped their second straight to fall to 8-21. They began the night tied with Houston for the majors’ worst record.

Alex Sanabia (2-4) took the loss for Miami, going five innings and giving up four runs (two earned) and six hits. He struck out four and walked two.

The Marlins took a 1-0 lead in the top of the first. Juan Pierre drew a leadoff walk, and after a single by Donovan Solano, he stole third, the 600th steal of his career. Pierre scored when Placido Polanco bounced into a double play.
