BOSTON – Tim Wakefield pitched eight strong innings and the Boston Red Sox moved a season-high 15 games over .500 with a 6-4 win over the Toronto Blue Jays on Wednesday night.

Kevin Millar and Bill Mueller each drove in two runs for Boston, which improved to 67-52 with its ninth win in 12 games. The Red Sox won all three games against Toronto for their first series sweep since July 6-8 against Oakland.

Wakefield (9-7) retired 13 consecutive batters during one stretch and left after throwing 104 pitches. He allowed two runs, five hits, one walk and struck out five.

But on the eve of his last complete game six years ago, an 11-1 win against Kansas City, he failed to get another. Keith Foulke pitched the ninth and allowed RBI singles to Kevin Cash and Alexis Rios with two outs. Frank Catalanotto flied out to deep left-center with two on to end it.

The Red Sox gave Wakefield plenty of support early, going ahead 4-0 in the first and 6-1 in the fourth against Miguel Batista (9-9), who is 1-4 in his last eight outings.

The Blue Jays scored in the third on Carlos Delgado’s sacrifice fly and in the eighth on a triple by Rios and a groundout by Vernon Wells.

They dropped a season-high 23 games under .500 (49-72) by losing for the 13th time in 15 games.

Wakefield put two runners on base in each of the first three innings.

But after Wells’ one-out, ground-rule double in the third, the knuckleballer retired 13 consecutive batters. The streak began with Delgado’s sacrifice fly that scored Catalanotto, who was hit by a pitch.

Gabe Gross broke the string with a two-out single in the seventh before Cash grounded out.

The Red Sox loaded the bases in the first on a single by Johnny Damon, an error by third baseman Eric Hinske on Manny Ramirez’s grounder and a walk to David Ortiz.

Millar’s double drove in two runs, Orlando Cabrera’s groundout scored another and Mueller’s single sent home the fourth.

Boston made it 6-1 in the fourth, scoring two runs with no outs. Cabrera singled and scored on Mueller’s triple.

Then Doug Mirabelli singled home Mueller.

Notes: Millar extended his hitting streak to 10 games and is 14-for-32 during that span. … Mirabelli has reached base in 19 consecutive starts. He has played in just 35 games as a backup to catcher Jason Varitek. … Toronto is 0-8 at Fenway Park since winning Boston’s home opener.
