That's all folks - Mayweather exits unbeaten after 49th win
Floyd Mayweather won his farewell fight with a rout of Andre Berto in Las Vegas that ensured the American finishes with a perfect career record of 49-0 and equals Rocky Marciano's milestone.
"It's part of boxing history," Mayweather said after a landslide points victory meant he matched the longest undefeated career in the sport, which Marciano established when he quit in 1955.
The champion added: "Records are made to be broken.
"Hopefully, we can now find the next Floyd Mayweather who can break the record. I want to be a part of it [as a promoter]."
The 38-year-old dominated much like the one-sided odds had suggested he would as he retained the WBA and WBC welterweight world crowns in the MGM Grand Garden Arena.
All three judges scored the fight heavily in the champion's favour: 120-108, 118-110, 117-111.
Mayweather put in a razor-sharp display, with his superiority reflected in the punch statistics.
He landed 232 of 410 punches, while Berto found his target with only 83 of 495.
It was typical Mayweather: hit and not be hit.
He sounded content that his career was finished, and was adamant that he would stick to his promise not to fight again. "Boxing is blood, sweat and tears," he said, having briefly sunk to his knees in victory following his 26th successful world title fight.
"Boxing is wear and tear on the body. My career is over. You got to know when to hang it up, and it's time for me to hang it up. It's official."
With 17 years of his 19-year career spent as a world champion, Mayweather has accumulated statistics and earnings that make him arguably the most successful boxer in history, with world titles won across five weight divisions from super-featherweight to light-middleweight, and overall earnings of close to $625m (€550m). His cut for his swansong fight was $32m (€28m).
"There's nothing else for me to accomplish in boxing. I made great investments, I'm financially stable. I had a great career.
"My record speaks for itself," he said.
However, here is a caveat. Officials at MGM Resorts will no doubt want Mayweather to christen the new 20,000-seat arena that it is building behind the Las Vegas Strip, which is due to open in April next year.
The stage is set for the master of publicity to accomplish what no other fighter has done and reach 50-0.
Never say never in boxing, - particularly when it comes to Mayweather.
