NEW YORK -- Philadelphia Phillies pitcher Carlos Silva was suspended for six games and Cincinnati Reds teammates Adam Dunn and Sean Casey each drew three-game suspensions Friday for a brawl last week.

Dunn, however, negotiated his suspension down to two games and began serving it Friday night at Arizona.

Phillies manager Larry Bowa also was suspended for one game for Silva's actions after a warning had been issued by the umpires.

All four were also fined by Bob Watson, major league baseball's vice president for on-field operations, for the brawl that took place in Cincinnati last Friday.

Silva was disciplined for intentionally throwing at Dunn, touching off the brawl.

Dunn was punished for charging the mound and acting aggressively. Casey was suspended for fighting.

Philadelphia pitcher Jose Mesa and catcher Todd Pratt were fined for their roles in the altercation.

Unless there is an appeal, the suspensions of Silva and Dunn were to begin Friday night with Casey's suspension scheduled to start next Tuesday. Bowa was suspended for Saturday's game against Boston.
