Floyd Mayweather may retire as one of the most successful boxers in history but he?ll never come close to one world record.
The 38-year-old American hopes to retain his WBC and WBA welterweight titles and remain undefeated in 48 fights when he meets Manny Pacquiao in Las Vegas in May.
He may still try to break Rocky Marciano?s record of retiring as undefeated world champion after 49 professional fights. This means he will have to win two more fights if he defeats Pacquiao, the WBO champion. But 50 seems unlikely because he has said he intends to retire at the end of this year.
Mayweather will certainly retire as the man who made more money from boxing than anyone else. It has been estimated that he earned more than $400 million from his first 47 fights. He may add another $180 million from the fight against the Filipino.
But ?Money? Mayweather won?t get even halfway to the record that a little Welsh flyweight, Jimmy Wilde, just over a century ago.
Wilde remained undefeated in 103 fights before Tancy Lee stopped him in the 17th round on January 25 1915. He drew once and won 102 fights in just over four years before lost for the first time in his career.
The remarkable Wilde, who held the undisputed world flyweight title, made his debut on Boxing Day 1910 and did not lose until Lee brought his run to an end.
Several other boxers have remained undefeated in more fights than Mayweather will other have. A Spaniard, Pedro Carrasco, who held the WBC lightweight title, was unbeaten in 93 fights in almost eight years ? from April 22 1964 to February 18 1972. He then lost to Mando Ramos.
Sugar Ray Robinson, still regarded as one of the best boxers in history, remained undefeated in 91 fights. His run of over eight years without defeat began on February 19 1943 and ended on July 10 1951 when he lost the world middleweight title to Randolph Turpin.
Robinson also held the world welterweight title in the days when there were only eight weight divisions.
BRIAN MITCHELL TOPS SA LIST
Brian Mitchell, a former WBA and IBF junior lightweight champion, tops the list of South Africans who remained unbeaten for an extended period.
After losing on points to Jacob Morake on May 3 1982, Mitchell remained unbeaten in 41 fights before he retired. He was held to a draw three times during this run.
But Nkosana ?Happyboy? Mgxaji rattled up more successive victories than Mitchell. He won his first 33 fights before losing to Anthony Morodi on June 24 1972. This makes him the SA boxer with the longest winning streak, as opposed to an unbeaten run, which could include draws.
After his first defeat, Mgxaji remained unbeaten in his next 39 fights before losing to Samuel Serrano in April 1979 in a challenge for the WBA junior lightweight title.
He eventually retired with a record of 88-9, including four draws and 26 wins inside the distance. He died in January 2001 at the age of 61.
