LAS VEGAS -- Manny Pacquiao and Juan Manuel Marquez square off at Mandalay Bay on Saturday in the rematch of their classic 2004 draw.

KEYS TO VICTORY
PACQUIAO'S KEYS MARQUEZ' KEYS
1. Use the right. Marquez got back into the first fight when he realized Pacquiao was doing nothing but throwing a right. Pacquiao needs variety in his attack. 1. Jab, jab, jab. Marquez will blunt Pacquiao's charge and open his own offense by keeping a double or trip jab in Pacman's face.

2. Cut the distance. Pacquiao will be more successful if he's able to force the fight to close range. 2. Hands high. Pacquiao tends to be a headhunter. Marquez can blunt this by keep his guard high and tight, essentially daring Pacquiao to go to the body.

3. Upper body movement. Marquez is a very straight and very accurate puncher. Pacquiao needs to make it difficult for him by moving his head and shoulders on the way in. 3. Right hand counter. Marquez had great success in the opener countering Pacquiao's left with a right of his own. There is no reason to abandon that.

4. Body, then head. An effective combination for Pacquiao will be if he hooks to the body and then brings it up to the head quickly. 4. Don't lay on the ropes. Pacquiao is a powerful puncher and Marquez can't afford to give him free reign to tee off.
