TORONTO -- Joe Torre felt "helpless" and Johnny Damon said the Yankees got their "brains beat in" by the Blue Jays.

No doubt about it, New York was happy to leave Toronto after another loss Sunday.

Vernon Wells hit two of Toronto's five homers and the Blue Jays scored eight times in the third inning of a 13-5 victory over the Yankees, who lost for the fourth time in five games overall.

"We certainly served it up today," Torre said.

Troy Glaus, Eric Hinske and Reed Johnson homered in the third, helping Shaun Marcum earn his first major league win. Wells and Johnson each had four RBI for the Blue Jays, who took three of four in the series and moved within two games of the second-place Yankees in the AL East.

"We could have easily taken all four," Wells said. "But you've got to be happy with three."

Toronto matched a season high with nine extra-base hits and scored 11 runs on five homers.

Sidney Ponson (0-1) struggled in his second start for New York -- allowing six runs, five hits and three walks in 2 1/3 innings.

Ponson hasn't won in nine starts, dating to his stint with St. Louis this season.

"I really expected something from Sidney today, but it just looked like he didn't have any command at all," Torre said.

Torre said Ponson deserves another start, but he doesn't know when it will be because of two off days coming up.

"I know the situation," Ponson said. "I'm not pitching like I used to. I don't know why."

Alex Rodriguez went 0-for-4 and is in a 4-for-27 slump. He was back at third base after a day as New York's designated hitter and didn't commit an error after making five in his previous five starts at third.

Rodriguez maintains he is happy with his approach at the plate.

"I still feel good," he said.

Toronto sent 13 batters to the plate and set a club record for runs in a third inning. The Blue Jays have played well since cutting disgruntled designated hitter Shea Hillenbrand.

"It was a long, hard week, big controversy, but the guys stayed focused," manager John Gibbons said.

Damon thinks the Blue Jays played better because of it.

"Dissension breeds winners. It seemed like they pulled together and came out playing with a lot of confidence," he said.

Glaus hit a two-run shot off Ponson, and Hinske and Johnson each hit a three-run drive off Kris Wilson. The club record for home runs in an inning is four.

Wells hit a two-run homer off Ponson in the first and a solo shot off Shawn Chacon in the fifth for his sixth multihomer game this season.

Marcum (1-0) allowed three runs and seven hits in five innings. He struck out four and walked one.

Marcum replaced Ty Taubenheim in the rotation. Taubenheim is recovering from an infection in his left foot.

Posada's three-run homer off Marcum gave New York a 3-2 lead in the third, but Toronto scored eight runs in the bottom half.

Toronto added two in the seventh on Johnson's RBI double and Wells' sacrifice fly.

Johnson went 3-for-5 and Wells finished 3-for-4.

Wells' only out was a loud one, a shot to the warning track that left fielder Melky Cabrera had to jump for.

"They just kept going up and swinging the bats at will," Damon said.
