DETROIT -- Max Scherzer allowed two runs in the first inning -- and by the time he took the mound again, he had a two-run lead.

It's been that kind of season for the Detroit right-hander.

Scherzer won his major league-leading 11th game without a loss and Victor Martinez hit a first-inning grand slam to lead the Tigers to a 10-3 victory over the Boston Red Sox on Saturday night.

Scherzer was terrific after that shaky beginning, and as usual his teammates gave him plenty of run support.

"It's nice to start a season 11-0. It just means we're playing great team baseball and I'm going out there and doing my job," Scherzer said. "I'm credited a ton of run support. That's when you've got to give all the credit to your teammates. Every time I feel like I go deep into a game, they're going to pick me up. They have the whole entire season."

Scherzer allowed a couple runs in the first, including a towering solo homer by David Ortiz, but Martinez's drive put the Tigers ahead to stay. Martinez also hit an RBI double in the fifth, and Scherzer shut down Boston after the first. He allowed two runs and six hits in seven innings.

Allen Webster (0-2) gave up five runs and eight hits in 4 1/3 innings. He struck out five and walked two.

"The four runs given back in the first set the tone for the entire evening," Boston manager John Farrell said. "I think he settled down after the first inning and pitched OK."

Red Sox reliever Franklin Morales yielded four runs, including a two-run homer by Omar Infante. Farrell said Morales could go on the disabled list because of left shoulder discomfort.

Scherzer became the first pitcher to start 11-0 since Roger Clemens in 1997, according to STATS. The last to start 12-0 also was Clemens, during a 14-0 stretch to begin his AL MVP season in 1986.

"I realize that it takes so many other teammates to put me in that position," Scherzer said. "This is a credit to the Detroit Tigers, for me being in this position. I know I've pitched well, and I know I've given my team a chance to win, but it doesn't always go that way."

The first two hitters singled off Scherzer, and Dustin Pedroia's double-play grounder gave Boston a 1-0 lead. Ortiz's 16th homer put the Red Sox up by two.

Detroit erased that deficit in a hurry. After singles by Austin Jackson and Torii Hunter, Miguel Cabrera drew a walk. Prince Fielder struck out, but Martinez's line drive cleared the wall in right for his third career slam.
