In the most anticipated fight of the decade and the richest bout of all time, Floyd Mayweather Jr. beat Manny Pacquiao in a unanimous decision to remain undefeated at 48-0.

Pacquiao was the more aggressive fighter early, and thrilled the heavily pro-Manny crowd in the middle rounds with a few left hands to Mayweather's jaw.

But ultimately Mayweather's legendary defense was too good. While Pacquiao threw a ton of punches, he could never get inside on Floyd, and most of his flurries amounted to nothing.

At one point Floyd even taunted Manny's punching power after a flurry:

In the end, Mayweather was Mayweather. His defense was fantastic, and he got in enough counters to do damage:

The judges scored the fight 118-110, 116-112, 116-112. The consensus in the boxing world is that it was the correct decision.

Pacquiao disagreed.

"I thought I won the fight," Pacquiao said after the fight. "He didn't do nothing."

Pacquiao didn't get destroyed in this fight, as some thought he might. But he might be the only one in the world who thought he won the fight. Mayweather is 48-0, and rightfully so.
