BOSTON - With Toronto's rotation ravaged by injuries left-hander Aaron Laffey was pressed into starting duty for the first time since July 19, 2010.
Laffey gave the Blue Jays an impressive outing, going six scoreless innings, giving up three hits and two walks with two strikeouts.
But turning the game over to the Jays bullpen in the seventh was Toronto's downfall, as the Red Sox beat the Blue Jays, 5-1, Tuesday night at Fenway Park.
After giving up a lead-off single to Mike Aviles, Laffey retired the next 12 batters before Adrian Gonzalez's double to left field to lead off the fifth. With two outs in the inning, he issued his first walk, to Darnell McDonald. But Brent Lillibridge, whom Boston acquired Sunday in a trade with the White Sox for Kevin Youkilis, popped out to second baseman Kelly Johnson to end the threat.
With two outs in the seventh, Jason Frasor gave up a solo home run to Jarrod Saltalamacchia, his 14th of the season. Luis Perez replaced Frasor, giving up a double to pinch-hitter Ryan Kalish. David Pauley entered, hitting pinch-hitter Daniel Nava with a pitch and walking Aviles before giving up a two-run single to Dustin Pedroia, with Aviles thrown out trying to go to third.
The Sox added two runs in the eighth, as the first three batters reached off Pauley - David Ortiz on a double to left, Cody Ross on a single to right, and Gonzalez on a run-scoring double to center - driving Pauley from the game with Scott Richmond replacing him. Will Middlebrooks' sacrifice fly scored Ross.
Daisuke Matsuzaka, making his fourth start of the season for the Red Sox as he tries to make his way back from Tommy John surgery in June 2011, again struggled in the first inning. He gave up a lead-off double to Brett Lawrie, who advanced to third when Colby Rasmus reached on a fielder's choice, scoring on Edwin Encarnacion's one-out single.
But Matsuzaka allowed no further damage in the inning and settled down after that. He held the Blue Jays scoreless for the remainder of his outing, but left with two on and two outs in the sixth. Reliever Scott Atchison needed just two pitches to get out of the inning, getting Rajai Davis to ground into a fielder's choice.
Matsuzaka, who was not involved in the decision, went 5 2/3 innings, giving up one run on six hits and a walk with five strikeouts.
Andrew Miller pitched one-third scoreless inning to earn the win, improving to 2-0 with a 2.12 ERA.
Perez took the loss.
Alfredo Aceves earned the save, his 19th in 22 opportunities this season, with a scoreless ninth.
