LAS VEGAS — Floyd Mayweather Jr. was money once again in the richest fight ever.

Mayweather used his reach and his jab Saturday night to frustrate Manny Pacquiao, piling up enough points to win a unanimous decision in their welterweight title bout. Mayweather remained unbeaten in 48 fights with a win that cemented his legacy as the best of his generation.

"I thought I caught him many times. I was never hurt. I thought I won the fight. I hit him many more times than he hit me. I was very surprised with the scores. I had no problem handling his power. I thought I won," Pacquiao said.
