CHICAGO (Ticker) -- Sammy Sosa registered his first multi-homer game of the year as the Chicago Cubs slugged a season-high six home runs en route to a 9-1 hammering of the Milwaukee Brewers .

Corey Patterson and Sosa belted back-to-back homers off Brewers starter Ruben Quevedo (1-4) in the bottom of the first inning to put the Cubs ahead for good, 3-1.

Sosa's homer was his first at Wrigley Field since April 17 against Cincinnati.

Chicago had a 5-1 advantage with one out in the fifth when Sosa crushed a 1-0 offering from reliever Luis Vizcaino some 520 feet. The ball soared over the left field wall and traveled onto Kenmore Avenue.

"That's as far as I've ever seen a home run hit," Cubs manager Dusty Baker said. "I've seen Barry (Bonds) hit some out pretty far, but I don't think any farther than that one."

"I've been around major league baseball for 30 years. I've never seen a ball hit farther than that," Brewers manager Ned Yost added.

It was the 59th career multi-homer game for Sosa, who had just one home run in five games since returning from a seven-game suspension for using a corked bat.

"That was something out of a video game," Patterson said. "Human beings don't hit balls that far. We kept looking to see when it was going to land, but it never did. It just kept going through the trees."

With two out in the sixth, Chicago starter Kerry Wood (7-5), Mark Grudzielanek and Alex Gonzalez belted consecutive solo shots - each on an 0-1 count and over the left-center field wall - to open an eight-run cushion.

"I don't think I've ever seen that start with two outs and the pitcher up," Baker said.

It marked the ninth time in team history the Cubs registered three consecutive home runs and the first since September 29, 2001, when Fred McGriff , Rondell White and Todd Hundley accomplished the feat against Houston.

Not only did Wood hit his second home run of the season and sixth of his career, the righthander yielded just a run and scattered eight hits in seven innings. He walked one and struck out eight en route to his third win in four starts.

"I didn't have my better stuff," Wood said. "So I let the defense take care of me out there and the offense did their thing as well."

Geoff Jenkins smacked his 17th homer for the Brewers, who have lost five of their last seven games.

Yost and Milwaukee catcher Eddie Perez were ejected by plate umpire Andy Fletcher in the bottom of the eighth for arguing balls and strikes.

"I still don't know why he threw me out," Perez said. "I talked to him about a few pitches, but that was three or four minutes before he told me I was gone. He definitely missed a couple of pitches."

"It was a difference of opinion," Yost added. "He's a good umpire, I just thought he missed two or three crucial pitches. He gave me a lot of room to walk away, but I hung around too long."

Cubs catcher Damian Miller left after the fifth due to a sore right foot.

The game was delayed 16 minutes in the first inning due to a power failure.
