Filipino Manny Pacquiao insists his upcoming title bout against Timothy Bradley will be the last of his prodigious career and on Thursday said he is aiming for a convincing win to help bolster his campaign for a Senate seat.
Pacquiao, who has a 57-6-2 record and won world titles in eight different weight classes in a 20-year career, is set to battle Bradley in Las Vegas on April 9 for the American's WBO welterweight championship.
"This is my last fight," Pacquiao, 37, told a Madison Square Garden news conference on Thursday. "After this I'm going to retire and hang up my gloves and focus on my other big responsibility in my daily life, to help the people."
Pacquiao is a congressman in the Philippines but is hoping to secure a Senate seat in the May 9 election back home.
But first comes a boxing rubber match.
Bradley, (33-1-1, 13 KOs), won a highly controversial split decision against Pacquiao in their first meeting in 2012.
Pacquiao then won their 2014 rematch in Las Vegas with a comfortable unanimous decision to end Bradley's undefeated record.
The American, now working with trainer Teddy Atlas, knocked out Brandon Rios in the ninth round of his last bout.
"Teddy and I and the team are going go to the lab and I'll come out a smart, smart monster on April 9," said Bradley, who has credited Atlas with improving his ring skills.
The Filipino slugger (57-6-2, 38 KOs) said he is anticipating a sterner challenge from Bradley in their decisive bout.
"I chose Bradley again because he's different from before," Pacquiao said.
"He's improved a lot."
Bradley meanwhile also warned fans to expect a different fight to the previous two bouts.
"I've heard that Manny Pacquiao chose me because he knows me," Bradley said.
"I think it's different now. I honestly do. "I think this will be a different fight than the first two altercations. That's all I can tell you. It's going to be a great fight - he wants it really badly and so do I."
Pacquiao told reporters he has recovered from surgery to repair a torn rotator cuff in his right shoulder that limited him in a loss to Floyd Mayweather last May and that on Wednesday he received an all-clear from his surgeon.
Looking slender in a business suit, Pacquiao snapped off a pair of sharp right jabs to illustrate that his daily basketball workouts and ocean swims had helped him heal.
Pacquiao, who insists he won two more rounds than Mayweather in their so-called "Fight of the Century," said TV coverage of his training would offset loss in campaign time back in the Philippines as he prepares for the Bradley bout.
"I'm campaigning to have a good fight," he said. "If I win this fight convincingly that will excite the people."
Pacquiao admits a rematch with Mayweather, who has already retired, was his first choice for a final fight.
And if Mayweather were to reconsider and offer Pacquiao a rematch?
"I'll ask the people of the Philippines," Pacquiao said.
