Las Vegas

Undefeated Floyd Mayweather won the World Boxing Association super welterweight title with a unanimous points decision over Miguel Cotto on Saturday at the MGM Grand in Las Vegas.

The American, who stepped up in weight to fight Cotto, used his superior hand speed and solid defence to take the fight on all three judges’ scorecards after 12 rounds, in what will go down as one of his toughest fights.

“You got to suck it up and fight hard,” Mayweather said. “Miguel Cotto was a tough competitor. I had to execute the game plan and fight my heart out.”

Cotto, of Puerto Rico, made Mayweather work for the victory as he clearly won some of the middle rounds and showed a willingness to engage Mayweather in the centre of the ring and on the ropes.

But Mayweather rallied late on and took the title with scores of 117-111 on two judges’ cards and 118-110 on the third, extending his unbeaten run to 43-0 with 26 knockouts.

Future hall of famer

“Miguel Cotto is a future hall of famer,” Mayweather said. “He is no push over.”

The fighters exchanged vicious punches in the 12th round with Mayweather landing the better of the shots. He appeared to wobble Cotto twice but couldn’t knock him down.

Mayweather, 35, said he hasn’t given up on trying to work out a deal on a mega fight with Filipino star Manny Pacquiao. Their previous talks have been scuttled by a number of issues, including the sharing of pay-per view revenue and drug testing.

“The fight I was looking to fight was against Manny Pacquiao,” Mayweather said. “I don’t think the fight would happen because of (Pacquiao’s promoter) Bob Arum. “Let’s give the fans what they want to see.”

It marked the 20th career title fight for Mayweather and the first time he has fought at 154 pounds since beating Oscar De La Hoya in 2007.
