Las Vegas - Floyd Mayweather earned a unanimous decision over Andre Berto to claim his 49th and he says final victim in a glittering unbeaten ring career spanning two decades.
All three judges ruled overwhelmingly in Mayweather's favor and afterwards the American welterweight world champion confirmed that he was retiring, saying: "My career is over.
He equals the perfect 49-0 record of heavyweight legend Rocky Marciano and retains his WBA and WBC titles, embellishing his reputation as the best boxer of his generation.
Mayweather fell to his knees in the ring after the bell, taking in the moment. The judges ruled it 118-110, 117-111 and 120-108.
Golden Boy Promotions President Oscar De La Hoya, who lost a close split decision to Mayweather in 2007, was happy to see Mayweather leave.
Although De La Hoya's company co-promoted most of Mayweather's fights from 2007 to 2014, the two of them always had a tense relationship.
"I'm going to miss Floyd's action packed fights with prime fighters. I'm sure glad I decided for Disney movies with my kids tonight. Now that the worst boxing era is over let's look forward to the next 10 years [with] Canelo, Cotto, Lemieux, Golovkin," De La Hoya told his social network followers.
