Four District boxers captured championships last night at the fifth annual Mayor's Invitational Amateur Boxing Tournament. Willie Senn, Cecil Thompson and Sylvester Tibbs each earned decisions, but Curtis Peoples provided the excitement of the evening at Coolidge High School.

Peoples brawled for every second of his three-round bout with native Washingtonian Keith Kemp, who fought for the Fort Bragg, N.C., team. Despite being knocked down in the second round, Peoples rebounded, slugging Kemp with repeated left-right combinations to end the fight.

"I was much quicker and stronger and that helped me," Peoples, 19, said.

The first bout (106 pounds) was close and action-packed, with Senn outpointing Jerome McIntyre of Philadelphia. Thompson had little trouble, dominating his fight against David Williams of Fort Campbell, Ky., from the outset. After Thompson (119 pounds) landed a pair of right jabs that stunned his opponent, he bloodied Williams's nose midway through the final round.

Tibbs (165) decisioned Fort Bragg's Roy Payne.

The championship card featured teams from the District, Norfolk, Fort Bragg, Philadelphia, Fort Campbell and Elmira, N.Y.

Other winners included Fort Bragg's Byron Moore (112), Patrick Washington (139) and Keith Mullings (156) and Norfolk's Lionel Butler (132).
