BOSTON — Boston scored five runs in the fifth inning, but this time the Red Sox did not blow a lead.

They were trailing by 10 runs before that rally.

Boston managed no more offense as Toronto beat the Red Sox 13-5, before a sellout crowd of 36,296 at Fenway Park, completing the Blue Jays’ three-game sweep, and extending Boston’s losing streak to six games.

The Red Sox also fell 10 games below .500 (27-37) for the first time. They remain in last place in the American League East, dropping to eight games back.

“We’re not in a good place right now as a team,” Red Sox Manager John Farrell said. “We’re not executing completely.”

Toronto (34-30) won its 11th straight.

Rookie starter Eduardo Rodriguez (2-1) got roughed up for the first time, allowing nine runs on eight hits and three walks over 42/3 innings.

Rodriguez, who gave up one run total in his first three starts, cruised through three innings. Then the trouble began. Ryan Goins capped a five-hit, six-run fourth inning with a three-run home run.

In the fifth, Rodriguez retired the first two batters, but yielded a walk and an RBI single – on a fly ball that dropped in after right fielder Alejandro De Aza called off the infielders, but could not reach it.

Russell Martin followed with an RBI double. Steven Wright relieved Rodriguez and gave up a Danny Valencia two-run homer, for a 10-0 lead.

Toronto starter Marco Estrada (4-3) got touched for five in the fifth – RBI singles from Dustin Pedroia and Hanley Ramirez, and a three-run home run from David Ortiz, his ninth of the season.

But idea of a comeback faded as the game went on, especially when Toronto put up three more in the seventh.

NOTES: Ortiz’s home run was his 475th, tying him for the 29th on the all-time list, with Stan Musial and Willie Stargell. … Former Sea Dogs first baseman Travis Shaw was recalled briefly from Pawtucket. He batted once Sunday and lined out to left. After the game, he was reportedly sent back down. … Reliever Matt Barnes was sent down to Pawtucket. Barnes, who has a 4.24 ERA, will continue to work out of the bullpen in Triple-A. …

Slumping Mike Napoli (.200) was given a second day off. Farrell said Napoli would play Monday. … Mookie Betts missed a second straight day after suffering a lower back strain when he crashed into the center field wall Friday. He took batting practice Sunday and appears ready for Monday. …

Pitcher Justin Masterson remains on the disabled list and will get his fourth rehab start Tuesday with Pawtucket.
