The opening two rounds saw both fighters be measured in their attack. In Round 3, Pacquiao began to open up and landed a left hand that sent Mosley down. Following the knockdown, an already stiff-legged and tense-appearing Mosley turned almost wholly defensive for the remainder of the bout. Pacquiao came forward and threw but Mosley, following the knockdown, seemed to have little interest in exchanging. He threw predominately a jab and retreated as Pacquiao moved in. To the chagrin of those in attendance and commentating, both fighters often seemed overly friendly and touched gloves repeatedly throughout the fight both before and after rounds and numerous times as the rounds were underway. Among the largest connections of the night were head clashes, which plagued the bout despite neither fighter developing a cut. In Round 10, Pacquiao went to the mat from a push as Mosley was standing on his foot. Referee Kenny Bayless, however, did not see it as such and ruled it a knockdown. Often to a chorus of boos, Mosley was content, and hinted at such in the post-fight interview, to accepting a decision loss to protect his status of having never been knocked out.
- "I just fought the best fighter in the world. He has exceptional power. I've never been hit like that before." - Shane Mosley
- "I couldn't move because my left leg got tight" Pacquiao said. "It's a problem I have been having." Added trainer Freddie Roach: "He came back in the fourth round with muscle cramps in his left leg... It was a very gutty performance in my mind because of his leg."
- "Since Manny Pacquiao moved up in weight and took on Oscar De La Hoya, Ricky Hatton, Miguel Cotto and Antonio Margarito, we got used to war... It didn't happen tonight." - ESPN's Brian Kenny
