Form

Through three bouts, the form of both fighters has been flawless. Pacquiao and Marquez arrived at the end of each fight with the same energy they entered it with and, in one of sports' most demanding endeavors, they've occasionally discovered a second wind. For this fourth battle, expect a similar story despite the advancing age of both men. Although Marquez is nearly 40, his preparation and fitness are that of an athlete 10 years younger. Pacquiao, 33, has begun to show signs of slowing down after 60 professional fights -- only one fewer than his rival -- but Pacquiao is still Pacquiao when it comes a Marquez fight.

Advantage: Even
