Jorge Posada tried to find A.J. Burnett after his game-ending hit Saturday. He darted away when Joba Chamberlain jumped in front of him, and Burnett crept up for a direct hit with one of his whipped cream pies.

Just another fun day at home for the New York Yankees.

Posada singled in the winning run in the 12th inning to lift New York to a 6-5 victory over the Toronto Blue Jays, coming up with the clutch hit after a rough game behind the plate.

“Jorge had a great day and he got banged up a lot,” manager Joe Girardi said. “I kept asking him how many fingers I was holding up and for the most part his answers were close enough.”

Posada also homered in his first game back after missing New York’s 4-2 win over the Blue Jays on Friday with a sore left thumb. He admitted to being partly relieved when the long day was over.

“The win was the most important thing,” he said. “The bullpen did an amazing job, keeping us in the game and giving us a chance to win.”

With one out and runners on first and second, Posada lined a 1-1 pitch from Shawn Camp (0-4) into center field. Alex Rodriguez scored without a play as the Yankees poured out of the dugout to congratulate Posada near first base.

New York has won nine of 10 to move a season-best 14 games above .500 and pull within a game of AL East-leading Boston, which lost 3-2 to Seattle. Brett Tomko (1-2) pitched a scoreless inning for the win.

“They have a good lineup so you’ve just got to hope that you can hold them for a few innings, score some runs yourself,” Blue Jays manager Cito Gaston said. “Otherwise they will come back and beat you.”

Former Highland High School star Adam Lind hit a two-run homer and Alex Rios had three RBIs for Toronto, which has lost six of seven. Scott Rolen doubled in the fourth and is batting .407 (35 for 86) during his career-best 21-game hitting streak.

“We’re not playing bad. We’re just not playing good enough,” Lind said. “Just need to score more runs.”

Johnny Damon and Hideki Matsui also homered for the Yankees, who lost starter Chien-Ming Wang to a strained right shoulder and bursitis in the sixth inning. Wang, who missed time earlier this season with weakness in his hips, went for an MRI that revealed the injury.

“It was unfortunate because I thought today was his best start,” said Girardi, who wasn’t sure yet what the Yankees would do about Wang’s next turn in the rotation. “He’ll need some rest.”

New York improved to 25-15 at the new Yankee Stadium, where 135 homers have been hit already this season. The Yankees will reach the halfway point of their home slate on Sunday afternoon against the Blue Jays.

The Yankees led Roy Halladay and Toronto 3-2 before the Blue Jays rallied in the sixth. Marco Scutaro led off with a double and Lind hit a one-out drive over the wall in right for his 17th homer.
