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.
At a 16,000 sell-out MGM Grand Garden Arena in Las Vegas - where some spectators had paid as much as $350,000 for tickets on the resale market - Mayweather, 38, started much the better of the two fighters.
Mayweather bossed the early rounds before Filipino Pacquiao had success in the fourth with a couple of strong left hooks to the head
