BOSTON -- Jonathan Papelbon is perfect no more.
The Red Sox rookie gave up his first run of the season since becoming Boston's closer, allowing Russ Adams' tiebreaking double in the ninth inning that gave the Toronto Blue Jays a 7-6 victory on Wednesday night.
"I let my team down, but tomorrow I'll be ready to go," said Papelbon, who was the AL Rookie of the Month with 10 saves in 10 tries and a 0.00 ERA in April. "There's a long way to go, and I have a lot of innings to pitch."
Toronto led 4-3, trailed 5-4 and then took a 6-5 lead in the seventh before Boston tied it again in the eighth.
But with Papelbon pitching in the ninth, Lyle Overbay led off with his fourth hit of the night. Gregg Zaun singled one out later, and Adams doubled down the right-field line to stop an 0-for-14 slump.
"When you're down a run or two, we know we can come back," said designated hitter Shea Hillenbrand, who homered for Toronto. "Tonight, it was Russ. He hadn't been swinging the bat well, and he came through."
Dustin McGowan (1-0) allowed two hits in one inning, getting Alex Gonzalez to pop up a sacrifice attempt with runners on first and second, nobody out and the tying run already in. Kevin Youkilis grounded into a fielder's choice, then Mark Loretta ended the threat with a strikeout.
B.J. Ryan pitched the ninth for his sixth save, striking out three and getting Jason Varitek looking with the tying run on third base.
Papelbon (0-1) gave up his first run after 21 1/3 innings dating to Sept. 19.
"I didn't feel great today, but that's not an excuse," he said. "I've felt bad other days and was still able to get the job done."
Overbay went 4-for-4 with a walk for the Blue Jays, who improved to 5-2 against Boston this season as they try to interrupt the dominance in the AL East by the Red Sox and Yankees. Boston has lost eight of its last 12.
The start of the game was delayed 10 minutes because of rain, and though it was 46 degrees and raw, the game wasn't interrupted. But it wasn't the best weather for starters Josh Beckett or Roy Halladay, and the expected marquee matchup dissolved in the drizzle.
Beckett gave up four runs, five hits and three walks, throwing 101 pitches in just five innings and leaving without a decision. He's allowed 16 runs in his last nine innings.
Halladay allowed five runs, nine hits and two walks, striking out two in six innings. He gave up three runs on five consecutive singles in the second, then two more in the sixth when Mike Lowell singled in a run and scored on Wily Mo Pena's double to make it 5-4.
"It was a tough night to pitch," Toronto manager John Gibbons said. "The conditions, with all the moisture out there ... but you could probably count on one finger how many times you've seen him get a lead and give it back."
But the Blue Jays took the lead back in the seventh when Overbay doubled off Keith Foulke with two outs and Hillenbrand hit his fourth homer. Hillenbrand is 9-for-22 on the trip and has raised his batting average from .217 to .341 over his last 13 games.
David Ortiz, who homered in five of his first six games against Toronto this year, went 0-for-5 and only hit the ball out of the infield once.
In the bottom of the first, second baseman Aaron Hill got hit in the chin by a bad-hop grounder. He went to the dugout to tend to his bleeding chin, but returned a few minutes later. He had a two-run double in the second, when the Blue Jays took a 3-0 lead.
With his first-inning single, Vernon Wells has hit in 24 of the Blue Jays' 26 games. ... LHP David Wells (right knee sprain) and RHP David Riske (lower back strain) are close to being able to pitch again, manager Terry Francona said. ... Lowell's eighth-inning single was his 1,000th career hit. ... Boston hadn't lost a one-run game at Fenway Park in more than a year. Their 18 victories in a row tied a major-league record.
