ALL SIGNS POINT TO SMASHING KNOCKOUT WIN

LAS VEGAS—With all the lessons he has learned  in the art of fighting counterpunchers and all those days of training hard and studying his opponent’s films,  Manny Pacquiao is ready to explode.

“I’m so excited already,” Pacquiao said. “Let’s get it on.” And this three days before the fight. With the promise of a vastly improved performance and a definitive end to one of the more compelling debates in boxing, the world’s acknowledged pound-for-pound king is going all out against Juan Manuel Marquez on Saturday (Sunday in Manila) at the MGM Grand here.
