CLEARWATER, Fla. (AP) _ Michael Rush won the National Boxing Association cruiserweight title by stopping Pedro Riveron in the seventh round of a scheduled 12-round bout Friday night.

Referee Brian Garry ended the fight at 1:34 of the seventh after Rush landed 18 consective punches.

``He took all I had and he didn't go down,'' said Rush, of Tampa, Fla.

Rush (19-4-1) clearly dominated from the outset. He staggered Riveron (10-7) with a hard left to the jaw as the sixth round ended, setting up the flurry of punches to open the seventh.

Riveron, a Cuban native now residing in Miami, had recorded three straight knockouts as a super middleweight coming into this fight.

Rush is a former No. 1-ranked IBF heavyweight contender. He is currently ranked No. 3 in their cruiserweight division.

In another bout, Gerald Mitchell of Daytona Beach, Fla., took a unanimous decision from Larry Carlisle of Naranja, Fla., in a eight-round heavyweight fight.
