Kelvin Daly said he never doubted he had the ability to be a top boxer, even though he is 33 and just coming off a five-year sabbatical. Friday night, the Hyattsville resident received his validation.

Daly scored a six-round unanimous decision over Luis Rosales of Washington in a junior welterweight match, earning his first victory in four fights since returning last year. Daly's win--scored 58-55 by all three judges--came in the third of five fights at the Waldorf Jaycees Community Center sponsored by the Maryland State Athletic Commission.

In the first fight, heavyweight Donald Colbert of Chester, Pa., won a four-round split decision over Upper Marlboro's Terrance Wood. In the second fight, middleweight Bruce Corby of Scranton, Pa., scored a fourth-round technical knockout over Donnie Parker of Baltimore, in a fight that was halted by the physician.

Daly, who was born in Guyana and moved to New York City when he was 10, improved his career record to 12-6 with nine knockouts. Rosales, a 23-year-old native of Nicaragua, dropped to 3-5 with two knockouts.

"Most fighters, when they come back, they lose their first fight, then they give up," Daly said. "I'm not going to give up. I'm going to keep fighting until I get back to my natural ability. I think I'm a world-class fighter. You'll see my name around."

Daly said Rosales thumbed him in his right eye during the third round, leaving him blinded for the round's remaining 40 seconds. Later, Daly was cut above his left eye. But he persevered, and the two fought a fourth round that brought the crowd of about 500 to their feet. The final two rounds were more tame, as the two seemed to tire.
