TORONTO -- With the help of a big offensive performance, Carl Pavano got his first win with the New York Yankees.
"No matter how many runs we scored, no matter how long he was sitting down, he went out there and was in command and that was so important for us," Yankees manager Joe Torre said. "This is the kind of offense we can throw at people, but what makes it possible is to go out there and control the game as a pitching staff."
Pavano, who signed a $39.95 million, four-year contract, didn't expect the victory to ease the pressure on him.
"I don't know if I'll ever be relaxed," he said. "I push for success. This was a good outing, and I know five days from now I'm getting the ball again and I expect to do even better."
New York entered with five losses in six games, tied with Tampa Bay for last in the AL East at 5-9. But for the second time in three games, the Yankees took a big early lead, going ahead 7-1 in the fourth inning.
Pavano (1-2) pitched well but didn't get a decision against Boston in his first start, then was knocked out by a line drive off his head against Baltimore and pitched poorly against the Orioles in his third.
He was in control against the Blue Jays, allowing two runs, just one of them earned. He struck out three and walked none.
"It just wasn't one of those wins where we outscored the other team," Torre said. "That was a great outing. He could have gone nine innings without a hit."
New York backed Pavano with 14 hits. Posada went 3-for-5, falling a triple shy of a cycle, and driving in four runs. He had an RBI double in the four-run fourth, singled in the fifth and hit his first home run of the season in the sixth.
"It's good to get that one and get rolling," Posada said. "It seems like when you stay short, good things happen, and this was a perfect example today."
Former Yankee Ted Lilly (0-2) allowed six runs and six hits -- including five doubles -- in 3 1/3 innings.
Yankees designated hitter Ruben Sierra left with a stiff right elbow after doubling twice. Center fielder Bernie Williams came out because of tenderness in his left knee after singling in the seventh.
"Sierra's going to probably be a few days," Torre said. "He had a little biceps strain."
Williams didn't expect to be out long.
"They don't think it's going to be that serious," he said. "I should be there tomorrow."
New York took a 3-0 lead in the second on consecutive doubles by Hideki Matsui, Alex Rodriguez and Sierra, and Tony Womack's broken-bat RBI single with two outs.
Toronto's Alex Rios tripled off the wall in right in the third and scored on Orlando Hudson s sacrifice fly, but the Yankees broke open the game in the fourth. After Posada's double, Derek Jeter and Bernie Williams had run-scoring singles and Rodriguez drew a bases-loaded walk.
Posada homered in the sixth off Matt Whiteside. Womack was hit on the left knee by a pitch during the inning but stayed in the game.
