MONTERREY, Mexico (AP) — Edwin Valero of Venezuela has defeated challenger Antonio DeMarco of Mexico in their WBC lightweight title fight.

Valero won Saturday’s fight on a TKO after DeMarco sat in his corner and declined to come out for the 10th round. DeMarco was well behind on points and, though he had no obvious injuries, officials said he retired on the advice of his handlers.

Valero improved 27-0 and has won every bout by knockout. DeMarco dropped to 23-2 with one draw. read more
