“This will be my hardest-fought battle,� said Pacquiao. “It’s been over three years since I have changed weight divisions and I will be doing it against the lightweight division’s world champion. I saw how he took the fight to Erik Morales in his last title defense and I’m expecting to see the same firepower out of him when we meet. But this is my drive for five. Five world titles in five different weight classes and I will not be denied. I am fighting for history, for destiny and for my people of the Philippines.�

“Manny Pacquiao has beaten many great fighters, especially Mexicans like Morales, Barrera, Marquez, Larios and Solis. That’s why they call him “The Mexicutioner,â€? said Diaz. “I will shock the world and beat Pacquiao at his own game, power for power. He’s a great champion but he’s fighting in my division – lightweight. I have worked too hard for this world title and I will not give it up to him.”

“Two world champions, at the top of their game, matching each other in speed, power, stamina and courage is a recipe for a great fight,� said Hall of Fame promoter Bob Arum. “Manny has never felt the power thrown at this weight class just as Diaz has never gone toe-to-toe with such a human dynamo. But Manny possesses an inner strength from his fellow countrymen the likes I have never seen as a promoter with over 40 years of experience. Manny is more than a national treasure to the Philippines, he is the very symbol of its national pride. He doesn’t fight for himself, he fights for his people. It’s a responsibility that no other athlete could, or attempt to, accomplish.�

“Boxing fans recognize that in Pacquiao vs. Diaz you have one of the sport’s best fighters and biggest attractions moving up in weight to challenge a bigger, stronger champion,â€? said HBOPPV’s Mark Taffet. “It’s a very intriguing proposition and we look forward to the event.”

Dubbed “Republica Enemy No. 1,” Pacquiao (46-3-2, 34 KOs), from General Santos City, Philippines, has blitzed through the best fighters Mexico has had to offer since 2003 including Erik Morales (KO 3, TKO 10), Marco Antonio Barrera (TKO 11, W 12), Juan Manuel Marquez (W 12, D 12), Oscar Larios (W 12), Emanuel Lucero (TKO 3), Hector Velazquez (TKO 6) and Jorge Solis (KO . Pacquiao was named 2006 Fighter of the Year by the Boxing Writers Association of America and The Ring magazine for his two spectacular knockout victories of Mexican icon and three-division champion Morales, as well as his dominating 12-round unanimous decision over former world champion Larios. The hard-hitting southpaw has won 22 of his last 23 bouts including 2007 victories over Barrera and Solis. Pacquiao’s 12-round split decision victory over Marquez earlier this year not only avenged a disputed draw from their 2004 battle, it also made Pacman a four-division world champion.

Diaz (34-1-1, 17 KOs), from Chicago, will be making the second defense of his title. He successfully defended it against the three-division world champion Morales last summer winning a hard-fought unanimous decision over the future Hall of Famer. Although behind on the scorecards early, Diaz remained cool and rallied before the raucous hometown Chicago crowd of 10,000 to capture the decision. He swept the championship rounds and won the decision by scores of 114-113, 115-113 and 115-112. With the victory, Diaz cemented his place among the best lightweights in the sport and one of the most popular and respected athletes in the sports-crazy town of Chicago. A member of the 1996 U.S. Olympic team, Diaz, with 12 years of experience as a professional, is more than prepared to handle the pressures that come with battling boxing’s pound-for-pound most exciting fighter.
