Floyd Mayweather emerged victorious from the most lucrative fight in history, beating Manny Pacquiao via a wide unanimous decision in Las Vegas.
American Mayweather, 38, delivered a defensive masterclass against his Philippine rival at the MGM Grand Garden Arena, making the necessary adjustments after only a few rounds before disappearing out of sight.
Mayweather, who added the WBO welterweight title to the WBC and WBA titles he already owned, was awarded the fight 118-110, 116-112 and 116-112 by the three judges.
With his victory, Mayweather also cemented his status as the greatest pound-for-pound boxer of his generation.
The five-weight world champion is now undefeated in 48 professional fights, stretching back 19 years.
Six-weight world champion Pacquiao, who falls to 57 wins, six losses and two draws, later blamed a shoulder injury for his defeat.
