Manny Pacquiao may have retired another Hall of Famer as he extended his winning streak to 14. The welterweight Pacquiao defeated Shane Mosley in a unanimous decision in Las Vegas' MGM Grand Garden Arena. Pacquiao said he would have finished Mosley if not for cramps in his left leg during the fourth round. "It was a gutty performance because of the handicap in his leg,” said his trainer Freddie Roach. "I fought the best fighter in the world," said Mosley. "He has exceptional power, I've never been hit like this before. Manny is as fast as I've ever fought." By the 11th round, Molsey was in retreat, trying to avoid his first knockdown loss. As to whether Mosley would join Oscar De La Hoya and Ricky Hatton as a retired Pacquiao opponent, he said “I'll have to think about that later.”
