-- Lamont Peterson, of Washington, D.C., defeated three-time light welterweight champion Rock Allen, 21-13, in the U.S. Amateur Boxing Championships on Friday.

Peterson lost to Allen, of Philadelphia, in last year's amateur semifinals and in the U.S. Challenge.

"I tried to go to his body and let him think he had an open shot when I was punching, then come hard to the head," Peterson said.

Andre Ward of Oakland, Calif., defeated Rommel Rene of Orlando, 15-0 for the light heavyweight title. It was Ward's third shutout of the tournament.

Featherweight Jose Perez Jr. of Fremont, Calif., won a 23-22 decision over Mickey Bey despite getting a gushing nosebleed in the first round.

Devin Vargas of Toledo, Ohio, won the heavyweight title over Aaron Williams of Detroit when the referee stopped the contest 1 minute 31 seconds into the third round.

Super heavyweight Jason Estrada of Providence, R.I., won a 15-6 decision over George Garcia of Glendale, Ariz.

Andre Dirrell of Flint, Mich., the 2001 featherweight champion, defeated Jesus Gonzales of Glenn Dale, in a 14-8 decision at middleweight.

Boxing Notes: WBC heavyweight champion Lennox Lewis can fight Mike Tyson, as long as that bout is followed by a mandatory defense against Vitali Klitschko. WBC Vice President Ruben Martinez said yesterday that Lewis has until June 30 to fight Tyson, a more lucrative fight than a bout against Klitschko.

"We want to let him have that," Martinez said. "But whoever wins that fight has to box for the title against Vitali Klitschko within 120 days."

Lewis pulled out of a proposed April fight against Klitschko, ranked No. 1 by the WBC, in hopes of a rematch against Tyson. He knocked out Tyson in the eighth round last year.

Klitschko's camp sued, saying it had a contract, but has dropped the suit because of the WBC's latest ruling.

Tyson has not agreed to another fight against Lewis, saying he needs more fights to prepare. But he is bound by a contract signed for the first fight to fight a rematch with the champion.

If Lewis fails to fight Klitschko, the WBC could declare the title vacant and have Klitschko fight the next best contender for the title.

Klitschko, 32-1 with 31 knockouts, is the older brother of Wladimir Klitschko, who lost the WBO title to South Africa's Corrie Sanders three weeks ago. . . .

In Hamburg, Dariusz Michalczewski stopped Derrick Harmon in the ninth round to defend his WBO light heavyweight title for the 23rd time. Michalczewski (48-0), of Poland, hit Harmon with eight consecutive punches and knocked the American to the canvas 62 seconds into the round. Harmon (23-4) got back up on his knees, but couldn't beat the count.
