TORONTO — Ryan Dempster won his second straight start and the Red Sox took advantage of a season-high 10 walks to beat the Blue Jays 3-1 Thursday night.
Dempster allowed one run and four hits in six innings. The right-hander retired 10 of the final 11 batters he faced.
Dempster, who is from British Columbia, is 6-0 in 10 starts in Canada, the first nine in Montreal.
"I'm looking for more expansion teams in Canada," he said jokingly. "That's kind of the goal. Maybe Vancouver will get a team, or Winnipeg or something, so I can hopefully keep that going.
"It was fun to get out there and pitch in the Rogers Centre," Dempster said. "I grew up watching the Blue Jays in the SkyDome."
Boston improved its major-league-best road record to 9-3 and won its seventh series in nine tries.
The Red Sox have won eight of 10 and are 20-8 overall, their best start since opening 20-7 in 2002.
The last-place Blue Jays lost for the 12th time in 16 games. Toronto dropped to 4-12 against AL East opponents.
Blue Jays left-hander J.A. Happ had his shortest start of the season, 3⅔ innings, and matched a career high with seven walks.
"There's a line between not giving in and making quality pitches, and I was constantly on the wrong side of that line," Happ said.
