Floyd Mayweather defeated Manny Pacquiao by unanimous decision on Saturday night at the MGM Grand in Las Vegas, uniting the WBO, WBA and WBC welterweight titles. The victory improves Mayweather’s career record to 48-0, making him undoubtedly the best boxer of his generation.

The fight was one of the most-anticipated in the sport’s history, and it will turn out to be the most profitable boxing match of all-time. With a multitude of celebrities in the arena, Mayweather silenced the pro-Pacquiao crowd for much of the fight.

Judge Dave Moretti scored the fight 118-110 for Mayweather. Judges Burt Clements and Glenn Feldman had it 116-112 for the unbeaten boxer.

"I knew he was going to win some rounds," Mayweather told Jim Gray after the fight. "He had moments in the fight...I was a smart fighter. I outboxed him."

Throwing 435 total punches, Mayweather landed 148 blows, including 81 power punches. Pacquiao threw six fewer punches than his opponent, landing just 81 total punches and 63 power punches.

Most of the action came in the first half of the fight, when the boxers were trading rounds. But Mayweather pulled away in the second half of the fight, as he eluded Pacquiao’s punches, which he landed with poor accuracy. Pacquiao ran out of steam in the final six rounds, dropping to 57-6-2 in his career, though he told Max Kellerman that he thought he should've been named the winner.

"It's a good fight," Pacquiao said. "I thought I won the fight."

Mayweather was boisterous at the end of the fight, taunting the crowd that was rooting for his opponent. He embraced Pacquiao after the fight, congratulating him for being a tough opponent.

Mayweather said he will retire after his next fight in September.
