The fight, which has Mayweather’s 48 game winning run on line, a record he has kept in his 19 years boxing career, is to take place around 5am on Sunday morning (11pm in Las-Vegas).
If he beats Andre Berto, he’ll match the late heavyweight champion Rocky Marciano’s career record of 49 wins, no losses, making him one of the best ever boxer alive.
Berto on the other hand is a two-time welterweight world champion, whose career stats read 30 wins, 3 losses, 23 knockouts, and despite losing three of his last six fights, latest odds shows a 16/1 chance of him winning, though relatively low compared to Mayweather’s 100/1.
