Shortstop Marco Scutaro had four hits and drove in four runs while left-hander Jon Lester struck out 11 in seven innings as the Boston Red Sox defeated the Toronto Blue Jays 14-0 on Tuesday.
The Red Sox outhit the Blue Jays 20-4.
Blue Jays right-hander Dustin McGowan pitched in the majors for the first time in more than three years and allowed five hits, three walks and three runs while striking out five in four innings of relief.
Lester (15-6) held the Blue Jays (70-72) to three hits and one walk with his 100-pitch outing.
Scutaro's four hits equalled his career best. David Ortiz also equalled his career best with four hits and added two RBIs. Adrian Gonzalez and Jarrod Saltalamacchia, who hit his 15th homer of the season, both drove in a pair of runs.
Josh Reddick hit his seventh homer of the season in the eighth against McGowan.
With the Red Sox (85-56) leading 11-0, McGowan entered the game in the fifth inning to make his first major-league appearance since July 8, 2008.
McGowan, who has come back from two shoulder surgeries, received an ovation from the Rogers Centre crowd. He was activated Monday from the 60-day disabled list after completing his minor-league rehabilitation assignment at double-A New Hampshire.
After giving up three hits and two runs in his first inning, he settled in and showed a fastball of 95 miles per hour. After walking the first two batters in the ninth, McGowan was replaced by Joel Carreno.
Toronto left-hander Luis Perez (3-3) lasted only 2 2-3 innings in the start as the Red Sox hammered him for 10 hits, including a two-run homer by Saltalamacchia, and eight runs.
Left-handed reliever Rommie Lewis gave up five hits and three runs in 1 1-3 innings.
Perez's move from the bullpen had gone well in his first three starts. After 29 relief appearances, he made three starts before Tuesday and was 1-0 with a 3.94 earned-run average.
But on Tuesday he gave up a double to Jacoby Ellsbury, the first batter of the game. He then struck out Dustin Pedroia, then gave up a double to Gonzalez.
A walk to Kevin Youkilis, singles by Ortiz and former Blue Jay Scutaro and a double by Carl Crawford had the Red Sox leading 4-0.
The Red Sox added two more in the second on a walk to Ellsbury, a single by Gonzalez and a double by Youkilis.
Two more runs came in on Scutaro's double and Saltalamacchia's homer.
With two runners on base and two out, left-hander Rommie Lewis came in to get the final out of the inning.
The Red Sox scored three in the fourth on an infield hit by Youkilis, doubles by Ortiz and Scutaro and a single by Darnell McDonald.
