PHILADELPHIA (Reuters) - The Milwaukee Brewers battered Philadelphia ace Roy Halladay and cruised to a 9-0 victory over the Phillies on Tuesday.

The Brewers scored a run in the second, third and sixth innings, then exploded for six runs in the seventh where they chased last season's Cy Young winner Halladay from the game and handed him his first loss of the season.

Casey McGehee slammed a three-run home run in the seventh against reliever David Herndon after he had replaced Halladay, who was charged with six runs in six and two-thirds innings.

Halladay was coming off a complete game win against the Washington Nationals on Wednesday but could not muster his top form.

"There was probably two or three pitches I want back," Halladay told reporters. "Some days those hits are right where guys are playing. Other days they aren't."

Prince Fielder had an RBI single to begin the seventh-inning scoring and finished 3-for-4. Erick Almonte added a two-run single in the inning.

Milwaukee outfielder Ryan Braun added three runs and two hits including a homer in the third.

Former Philadelphia pitcher Randy Wolf, who played with the Phillies from 1999-2006, tossed six innings and allowed just two hits to dominate his old team and give Milwaukee (9-8) their second win of the three-game series.

The Brewers will aim to complete the sweep on Wednesday.

Philadelphia (10-6) managed just two hits on the night as they were shut out for the first time this season.

"We want to be a good team," Wolf said. "(The Phillies), the reason they're in the playoffs every year is they have a good, balanced team."
