MANILA, Philippines – Manny Pacquiao has a chance to make history again on Saturday, as he becomes the first active senator to fight for a world title when he challenges Jessie Vargas at the Thomas & Mack Center.

Pacquiao, who has won world titles in eight different weight divisions, retired after beating Timothy Bradley in April, but later realized he couldn't walk away from the sport that made him a global superstar.

After winning a senate seat in the May 2016 national elections, Pacquiao soon announced that he would return to the ring to challenge the 27-year-old Vargas for the WBO welterweight title. He has had to juggle his responsibilities as a senator and a fighter, attending hearings in the morning before going to the gym in the late afternoon and sometimes at night.

It wasn't until the senate went into recess that Pacquiao flew to the United States to conclude his training camp at the Wild Card Gym in Hollywood, California.

"This is a historical fight," Pacquiao said on Wednesday in Las Vegas. "This is my first fight being a senator."

Manny Pacquiao admits that "it's not easy" being a senator working in an office then training for a fight.

"You have to discipline yourself and manage your time, and that's what I did," said Pacquiao, who boasts never missing a Senate session even during the run-up to the Vargas fight.

"I'm glad that I fulfilled my duty while training in boxing."

"I tell you this," Pacquiao added, chuckling. "Don't do this."

"Being a fighter and a senator is not easy, if you don't have the discipline. Good thing that God is good. He is giving me the wisdom and the knowledge to perform my duties as a legislator, a public servant and a boxer also."

Pacquiao's chief trainer, Freddie Roach, has praised the boxer throughout their camp, noting the renewed aggression, power and precision of the Filipino star.

Pacquiao has made it clear that he is as prepared as he can be for Vargas.

"I'm so excited for this Saturday (Sunday, Manila time)," he said. "I'm sure that it's gonna be a good fight. I feel what (Vargas is) feeling and that's why I prepared for it. I had to prepare myself, because I know the hunger of my opponent. I'm ready for that."
