CHICAGO — Even the windiest days at Wrigley Field hadn't produced a power display like this.

Edgar Renteria hit two of the Atlanta Braves' club-record eight homers in a 13-12 victory in 11 innings over the Chicago Cubs yesterday.

Marcus Giles hit a three-run homer and Adam LaRoche homered twice for the Braves. Atlanta also got solo shots from Andruw Jones, Ryan Langerhans and Brayan Pena to complete the three-game sweep of the Cubs, who have lost 21 of their past 25 games.

"Crazy day at Wrigley, that's the only way I can describe it," said Atlanta manager Bobby Cox, who saw his team blow a four-run lead in the ninth and then come back to win it thanks to Cubs third baseman Aramis Ramirez dropping a routine pop-up in the 11th.

The eight home runs by the Braves broke a club record set Aug. 3, 1967, against the Cubs in Milwaukee. Chicago also set a club record for giving up the most home runs in one game. The Cubs broke the old record of seven, most recently set Sept. 9, 2000, by Houston.

Pena set the club's franchise record in the seventh inning. He hit his first career homer leading off the inning against Cubs reliever Roberto Novoa making it 12-8.

Cox wasn't surprised by Atlanta's display of power.

"Whoever expects to hit eight home runs? You would take the bet that there would be eight home runs on a day like this because you don't have to hit the ball extremely hard to do it," Cox said.

After blowing a four-run lead in the ninth, the Braves scored in the 11th when Langerhans hit a routine pop-fly that Ramirez couldn't catch. Langerhans reached second on the error.

Ramirez was camped under the ball but lost concentration at the last second and had the ball bounce off his head.

"I just missed it. I thought I already had it and I took my eyes off of it. I have no excuses, I just missed the ball. It could happen to anybody," said Ramirez.

After a groundout advanced Langerhans to third, Giles followed with a single.

Phillies 6, Brewers 2: Ryan Howard hit a two-run homer in the fifth inning to help host Philadelphia salvage the finale of the season series.
