Floyd Mayweather Next Fight: Undefeated Champion Names Andre Berto as his Sept. 12 Opponent

Floyd Mayweather Jr. has named Andre Berto as his opponent for the Sept. 12 welterweight title bout. Although Mayweather is the heavy favorite to win, the undefeated champion stated that he would still be bringing his A-game.

"I always bring my A-game and this fight against Andre Berto is no exception," Mayweather said during the announcement. "He's a young, strong fighter who is hungry to take down the best. Forty-eight have tried before and on September 12, I'm going to make it 49."

Berto, who was an up-and-coming fighter and a 2004 Olympian, has lost three of his last six fights. Two of the losses were against Robert Guerreo and Victor Ortiz. Mayweather has defeated both of those fighters easily.

"Best believe that I plan to bring it to Floyd and I'm not concerned about what 48 other fighters have been unable to do," Berto said. "Somebody is getting knocked out and it won't be me."

This upcoming fight is the last one on Mayweather's six-fight, 30-month contract with Showtime and CBS. The champion has stated that he will be retiring after this fight.

"I want to give other fighters a chance," Mayweather said. "I'm not greedy. I'm fortunate to be a champion in two weight classes right now. I'm the undisputed welterweight champion. I have the WBC and WBA belt at super welterweight. I have the WBO, WBA and WBC at 147. It's time to let other fighters fight for the belts."

Despite Mayweather's statements, many people are speculating this will not be Mayweather's last fight. Two-time champion Amir Khan and ESPN's Stephen A. Smith believe that Mayweather will be back for fight number 50.

"I've never believed [Mayweather was going to retire in September]. I don't believe that. I think Mayweather knows that," Smith said. "I think Mayweather is using this [fight with Berto] as a tuneup, and then he's going to give Manny Pacquiao a rematch. It's almost one of those things where it's a tuneup, it's going to be perceived as a cake-walk in a lot of people's eyes. And he's like, 'I'm Money Mayweather, I'm giving you me on free TV. You don't have to pay for it at all. It's a tuneup similar to what Manny Pacquiao did to Chris Algieri. And then I'm going to come out of retirement and I'll fight a Manny Pacquiao, or a Miguel Cotto if Cotto is lucky enough to beat Canelo Alvarez.'"

Stephen Espinoza, executive vice president and general manager for Showtime Sports, added that he was surprised to hear that Mayweather wants to retire after this fight.

"Floyd has been completely consistent and hasn't wavered a bit in saying this is his last fight," Espinoza said. "He's still arguably the best fighter in the sport so it's somewhat surprising for him to step away now but I've never heard him say anything other than this will be his last."

Espinoza said in regards to Berto, "He's one of those fighters who never fails to entertain. His biggest flaw is he's probably too aggressive."

The fight, which will not be as lucrative as Mayweather's May 2nd fight against Manny Pacquiao, will be available on pay-per-view. It will take place at the MGM Grand arena in Las Vegas.
