LAS VEGAS -- The fact they're much bigger than when they first met eight years ago is undeniable. Manny Pacquiao and Juan Manuel Marquez have added bulk along with the pounds, and both have had to deal with those who suspect they didn't do it naturally.
Along with the fighters, the purses and attention have grown as Pacquiao and Marquez meet Saturday night for the fourth -- and presumably last -- time.
Marquez will try again to do what he hasn't been able to do in 36 evenly contested rounds against Pacquiao -- get a decision from the ringside scorecards.
"All I ask is for the judges to be objective," Marquez said. "They need to really see what is happening in the ring instead of what they think might be happening in the ring."
Pacquiao barely escaped with a majority decision over Marquez last November and lost a widely panned decision to Timothy Bradley in June. A loss to Marquez would perhaps derail any talk of a bout against Floyd Mayweather Jr. that would be boxing's richest ever.
"I have always been focused, but not like this fight," Pacquiao said. "There are no distractions in my mind."
Neither holds a title as they meet in a welterweight fight. Pacquiao is expected
It's a far cry from 2004, when Pacquiao and Marquez could barely fill half the arena as 125-pounders that resulted in a disputed draw. Pacquiao weighed in at the class limit of 147 pounds Friday, while Marquez was 143.
As is the norm in the sport, the fight needs some controversy to sell. This time it's about Marquez bulking up in ways a 39-year-old normally can't and the ties his strength coach has to steroid scandals of the past.
Angel Guillermo Heredia provided track and field athletes like Marion Jones and Justin Gatlin with steroids and human growth hormone, only to escape prosecution in the BALCO case by agreeing to testify for the prosecution.
"You can say anything you want but you have no proof," Marquez said. "Let's go together and I'll do any test you want."
Pacquiao, himself a target of suggestions by Mayweather's camp that he used something to grow, said he wasn't worried about it. "Let's give him credit for hard work," he said.
