Mayweather decisions Berto in last fight to remain unbeaten

His career winding down to its final seconds, Floyd Mayweather Jr. took a victory lap around the ring, his fist raised in triumph.

After 19 years of perfection in the ring, he deserved one final bow.

Mayweather capped a remarkable career with a typical Mayweather fight Saturday night, using his defensive wizardry to frustrate Andre Berto on his way to a decision so lopsided one judge gave him every round.
