Challenger Hector Camacho overwhelmed Jose Luis Ramirez tonight to win the World Boxing Council lightweight championship with a unanimous 12-round decision.

It is the second world title for Camacho (28-0), the former WBC super featherweight champion. Camacho, 23, knocked down Ramirez (90-5) with a crushing left in the third round. The blow sent blood streaming down the champion's face for the rest of the fight. Afterward, Ramirez was taking to a local hospital with a possible broken nose.

Ramirez, despite taking an enormous amount of punishment, never stopped chasing Camacho, trying to cut off the ring and force him into the ropes.

Judge Harry Gibbs scored it 118-111, Mike Jacobs scored it 119-112 and Newton Campos gave Camacho a 119-109 advantage.

Each fighter earned $400,000 for the bout.

"I was great," Camacho said. "I was unbelievable. I'm the kid of the '80s. I will dominate this game. From now on, every fight will be a million dollars, because this kid deserves it."

Asked who he might fight now, Camacho said, "(Wilfredo) Gomez is out there. I'll retire him. (Ray) Mancini is out there. I'll retire him, too."

Ramirez, 26, befuddled by Camacho's speed in the first two rounds, threw only three or four punches.

In the third, Camacho threw a sharp right jab and followed it with the hammering left flush on Ramirez's nose. Ramirez spun around, toppled to the canvas and struggled to his feet at the count of six.

In a preliminary bout, U.S. Boxing Association heavyweight champion Trevor Berbick of Miami retained his title with a majority decision over Mitch Green. Berbick is 29-4-1; Green is 15-1-1.
