TORONTO -- Edwin Encarnacion hit a pair of two-run homers Tuesday, lifting the Blue Jays to a 9-7 victory over the Boston Red Sox that snapped Toronto's four-game losing streak.
The Red Sox had their five-game winning streak end before a crowd of 22,915 at Rogers Centre.
In the seventh, Encarnacion's second homer of the night and ninth of the season put the Blue Jays back in front after David Ortiz gave Boston a 7-6 lead with a three-run double in the top of the inning. Encarnacion's blast to left came after Junichi Tazawa (2-1) walked Jose Bautista with two outs.
With his fifth-inning blast, Encarnacion became the 14th player to hit a homer into the 500 level at Rogers Centre. The feat has been done 17 times.
The Blue Jays added a run in the eighth against Joel Hanrahan on a single by J.P. Arencibia, a sacrifice by Maicer Izturis and a single Colby Rasmus.
Steve Delabar (2-1) picked up the win, and Casey Janssen earned his seventh save.
Ortiz, Mike Carp and Jonny Gomes each hit solo homers for the Red Sox.
Toronto shortstop Munenori Kawasaki, a defensive replacement, was charged with an error on a potential double-play grounder by Daniel Nava with one out in the seventh. Delabar replaced left-hander Aaron Loup and walked Dustin Pedroia to load the bases before Ortiz's double.
Blue Jays starter Brandon Morrow allowed six hits, including two homers, and three runs while striking out seven in five innings. He is still looking for his first win of the season.
Red Sox left-hander Jon Lester allowed six hits and six runs in six innings.
The Blue Jays scored a run in the first on a double to center by Jose Bautista. It brought home Rajai Davis, who walked with one out and stole second.
Toronto added three runs in the third, two of them on a throwing error by catcher Jarrod Saltalamacchia.
Brett Lawrie led off the inning with a single to extend his hitting streak to five games. Davis was hit by a pitch, and Bautista walked. Saltalamacchia's throw to first to try to pick off Bautista went into right field, and two runs scored. Arencibia's two-out double scored the other run.
Ortiz led off the fourth with his third homer of the season. Carp hit his first homer of the season with one out in the fourth to cut Boston's deficit to 4-2. Morrow walked Saltalamacchia, but the inning ended with Lawrie started a spectacular double play on Will Middlebrooks' hard smash to third.
Fifth-inning singles by Stephen Drew, Jacoby Ellsbury and Pedroia cut Toronto's lead to 4-3.
Encarnacion's eighth homer of the season, after a single by Davis in the fifth, increased the lead to 6-3.

Hanrahan, who had been out with a hamstring injury, was activated from the 15-day disabled list before the game. RHP Daniel Bard was optioned to Triple-A Pawtucket after Sunday's game to clear a roster spot. ... Boson LHP Craig Breslow (shoulder) is scheduled to make his next rehabilitation appearance with Pawtucket on Thursday. ... LHP Mark Buehrle (1-1, 6.35 ERA) will start Wednesday for Toronto against Boston RHP Clay Buchholz (5-0, 1.19 ERA). ... Toronto LHP J.A. Happ will start Thursday's series finale. The Blue Jays hope that RHP Josh Johnson (triceps) can start Saturday against Seattle so that RHP R.A. Dickey (back) could be given an extra day before pitching Saturday.
