Will Pacquiao move up from 130 to 135 pounds? And if he does, will he want to fight WBC lightweight champion David Diaz, Juan Diaz or someone else?
Juan Diaz has more gold to offer Pacquiao, but the big cash could come from a fight with David Diaz.
Juan Diaz added the IBF belt to a collection that already included the WBA and WBO lightweight championships after his fight with Julio Diaz ended a second into the 9th round Saturday. Now, only one title is missing, and he said, "Of course, I want all the belts."
Promoter Don King added, "We love (David) Diaz."
But they prefer Pacquiao, who beat Marco Antonio Barrera into retirement the previous week.
"I'd like to show my talents against a fighter of his skills," Juan Diaz said. "Pacquiao just fought an older Mexican warrior. Now, he ought to fight a young Mexican warrior like me."
Another possible opponent is Joel Casamayor, although Juan Diaz said, "He's an older fighter. I'd rather fight the best young fighters out there."
Juan Diaz (33-0, 17 knockouts) was relentless from the opening bell in dominating Saturday's fight. He kept his feet and fists moving, and never slowed down.
He landed several solid combinations early on, the crowd roared, but Julio Diaz remained standing. That cycle kept repeating itself until Julio Diaz's brother, a cornerman, told the referee to call it just as the bell to start the 9th round sounded. One judge had Juan Diaz leading 77-75, but the other two scored it 78-74 and 79-73.
It was the seventh title defense for Juan Diaz, who at age 20 became the second youngest boxer to win a world championship when he beat Lakva Sim in a unanimous decision for the WBA lightweight title in July 2004.
He added the WBO title in April, when Acelino Freitas' corner stopped their title unification fight at the end of the 8th round.
"I feel that I've matured a lot since I started," Juan Diaz said. "When I became champion at age 20, beat Lakva Sim, I wanted to fight all the champions right after that. My manager, my second father, Willie Savannah said, 'No, you've got to hold off for a little bit. You're not quite ready for it.'
"I was a little disappointed, but now I see that he was right. ... I feel that I've matured a lot, and I think that the best is yet to come."
