Cincinnati ? Adam Dunn hit his 21st home run and bowled over Philadelphia catcher Mike Lieberthal as the Cincinnati Reds pulled away, then charged the mound and touched off a brawl during a 15-1 victory Friday night.

Dunn went after reliever Carlos Silva, who threw two inside fastballs the next time he came to bat after his shoulder-down hit on Lieberthal while trying to score.

Dunn dropped his bat, tightened his batting glove and headed for the mound. Lieberthal dived and tackled Dunn from behind as the Reds slugger reached the mound.

Silva glanced a punch off the side of Dunn’s head as he lay on the ground.

Dunn and Sean Casey were ejected for the Reds. Silva, manager Larry Bowa and closer Jose Mesa also were ejected.

The sixth-inning brawl overshadowed a two-homer, five-RBI game by Jason LaRue and a breakthrough win for Jimmy Haynes (1-5), who pitched a three-hitter for his first victory since last Sept. 24.

The hard feelings grew as the Reds pounded Kevin Millwood (8-4) and turned the tables on the Phillies, who scored a club-record 13 runs in one inning during their last game at Great American Ball Park.

There were no incidents during the April 13 game, which the Phillies won 13-1.

But tempers flared as the Reds hit three homers, piled up 22 hits and mixed in a little rough-and-tumble play.
