There's only one Ricky Hatton, as his admirers constantly sing to anyone who will listen. Good thing, because if there were any more Ricky Hattons his devoted followers in England might never have time to do anything but sing. The problem for Hatton is there's also only one pound-for-pound champion in boxing. His name is Manny Pacquiao, and all he did his last time out was give Oscar De La Hoya such a beating that De La Hoya decided it was time to retire. That fight not only introduced Pacquiao to a lot of casual boxing fans, but prompted oddsmakers to make him a 2-1 favorite when he and Hatton meet on Saturday in a 140-pound (63½-kilogram) fight that is the first big bout of the post-De La Hoya era. Despite the lopsided odds, Hatton and his fans fervently believe he will be the one with his gloves raised when the fight finally ends. “I've been here before,” Hatton said. “People say (I'm) over-hyped, overprotected, a fat, beer-drinking Englishman. Well, I'm going to shock the world again.” A Hatton win might not be quite enough to shock the world, but it would deal a blow to the Philippines, where Pacquiao is such a national hero that there is talk about him running for president when he gets out of boxing. But while the Pacman was always huge at home, it wasn't until he stopped De La Hoya that many in American boxing began giving him his due as the best pound-for-pound fighter in the game. It's a mythical title, but Pacquiao has won enough real titles to justify his coronation. Though the Hatton fight is for a lightly regarded IBO crown, winning at junior welterweight will mean Pacquiao has won titles in six weight divisions, beginning at 112 pounds (51 kilograms). “If that happens, people will want to put my name in boxing history and that will be my legacy,” Pacquiao said. Both fighters had spectacular performances the last time they were in the ring. For Pacquiao it was the win over De La Hoya, but Hatton showed off some himself a few weeks earlier by stopping Paulie Malignaggi. Hatton's only loss came when he was stopped by Floyd Mayweather Jr. in the 10th round of their December 2007 fight, and his record and fan base were enough to get him a guarantee of $8 million for the scheduled 12-round bout. “Manny has not fought anybody that's going to put as much pressure on him with as much force and strength and power and hand speed,” Hatton said. “I'd like to think I'll be too much for him, but I think it's going to a wonderful fight.” Promoters claim the fight has already sold out the 15,000-seat arena at the MGM and are selling closed circuit viewing at other Las Vegas hotels. The two fighters have largely avoided the kind of trash talk that normally happens before big fights, leaving that to others in their camps. For Pacquiao that means trainer Freddie Roach, and for Hatton it's his new trainer, Floyd Mayweather Jr., the estranged father of the only fighter to beat him. Mayweather read a poem he wrote about the fight and did his best to taunt Roach. But Roach maintained his manners, for what promoter Bob Arum said was a good reason. Even in boxing sometimes there must be some decorum of sorts. “The trainer (Roach) is training a future president of the Philippines,” Arum said. “The people sitting here are already campaigning to be in the cabinet.” Pacquiao's mother, Dionisia, finally came to the US with her son for one of his mega-fights, but she still can't bring herself to watch him fight. “She is scared to watch it live,” Pacquiao said. “To have her here, it's going to give me more inspiration to do my best and win. It's going to be one of the best times I've had in my life.” Mom plans to pray for her son while he is in the ring. “I'm not scared,” she said through a translator. “I'm confident he's going to win. Manny is going to go all the way.” Pacquiao has built a house for his mother near his own in the Philippines. His mother had avoided joining her son on prior trips owing to her frail health and “to take care of everything at home so it was ready when Manny got home.”
