Fight of the century: Mayweather beats Pacquiao

Floyd Mayweather claimed a unanimous points verdict over Manny Pacquiao to win the richest fight in boxing history and maintain his perfect record.

Mayweather, unbeaten in 48 professional fights stretching back to 1996, retains his WBC and WBA welterweight titles and takes the WBO belt from Pacquiao.

The American was caught with the odd good shot, but was quicker throughout and always looked in control.

The judges scored the fight 118-110, 116-112, 116-112.
