Newz Forum: BOXING: Viloria stays undefeated as pro flyweight

TUCSON, Arizona (AP) - Brian Viloria defended his North American Boxing Federation flyweight title Friday with an 11th round knockout of Mexico's Gilberto Keb Bass.

Viloria, from Waipahu, Hawaii, used a powerful left hook to the body that sent Bass to the canvas in the scheduled 12-round fight. He improved to 15-0 with nine KOs. Keb Bass fell to 22-11-1.

Viloria, a two-time junior Olympic gold medalist, beat Keb Bass' brother, Juan Alfonso, on Feb. 13 in Connecticut in his fourth title defense.
