Floyd Mayweather beats Andre Berto to make it 49-0
Floyd Mayweather made it 49 straight wins with a wide points victory over Andre Berto in Las Vegas.
The challenger was game but his fellow American, who was defending his WBC and WBA welterweight titles, was simply too difficult to hit at the MGM Grand.
Mayweather, 38, was awarded the verdict 120-108, 118-110 and 117-111.Mayweather was adamant it was his last fight, but having equalled Rocky Marciano's career record of 49-0, he might decide to have one more.
"My career is over, that's official," said five-weight world champion Mayweather, widely regarded as the greatest fighter of his generation.
"You've got to know when to hang them up. I'm close to 40 now. There's nothing left to prove in the sport of boxing. Now I just want to spend time with my family"The 32-year-old Berto is a two-time welterweight world champion and came into the fight having lost only three of his 33 professional bouts.
But those three defeats came in his previous six contests and pretty much nobody gave him a chance against Mayweather, whose unbeaten streak goes back to 1996.
Mayweather made $34m (£22m) for his latest outing but few expect him to fulfil his promise to retire.
