The Billion-Dollar Bout between undefeated champion Floyd Mayweather Jr., 38, and challenger Manny Pacquiao, 36, is over, with Mayweather declared the winner in a unanimous decision by the judges. Pacquiao was the aggressor throughout much of the "uninspiring" match, but Mayweather landed better shots. After the judges' decision, Mayweather climbed into the ropes and crossed his arms in a smirking pose. The crowd rewarded him with a wave of boos. Mayweather's record is now 48-0, and out of an estimated purse of $300 million, he was guaranteed 60 percent, win or lose, making this fight the highest grossing bout in history.
