Undefeated five-division champion Floyd Mayweather Jr claimed a unanimous decision in a feisty encounter against Marcos Maidana to successfully defend three world titles and improve his record to 47-0 on Saturday.

The official judges scored the fight 115-112, 116-11 and 116-111 for Mayweather.

In just the second rematch of his 18-year career, the 37-year-old American came out on top on all three scorecards, retaining his World Boxing Association (WBA) and World Boxing Council (WBC) welterweight and light-middleweight belts.

The victory was another masterful showcase of evasion from Mayweather, widely regarded as one of the best defensive fighters of all-time, as he danced out of danger and used his lightning counter punching to great effect.
