Mayweather Jr. found himself in front of a real fight against Miguel Cotto on Saturday, and still managed to find a way to win. Using his accuracy and speed, Mayweather won by unanimous decision : two judges scored the fight 117-111, and the third had it 118-110.

Fighting just a few weeks before he enters a county jail to serve a three-month sentence for domestic abuse, Mayweather found himself in a tough fight against a game opponent who never stopped moving forward. But he was faster and more accurate than Cotto and seemed to wear him down in the final rounds.

In the last round, Mayweather landed his best punch of the night, a left uppercut that seemed to hurt Cotto. He followed that with several flurries to the head to wrap up a decision that until the later rounds had been in doubt.

The decision was roundly booed by the crowd at the MGM Grand arena, which cheered wildly every time Cotto landed a punch.

Along with the winner, singer Justin Bieber and rappers Lil Wayne and 50 Cent went up in the ring at the MGM Grand Garden Arena in Las Vegas to celebrate his victory over Miguel Cotto in the impressive fight.
