Floyd Mayweather Jr Cements Legacy With Manny Pacquiao Win

Floyd Mayweather Jr cemented his place among the pantheon of boxing greats by improving to 48-0 with a unanimous decision over Manny Pacquiao on Saturday in a fight that lived up to its immense hype and price tag.

Mayweather weathered an early assault from the Filipino southpaw before winning the later rounds using his reach and jab to finish ahead on all three scorecards in a welterweight showdown set to be the top grossing prize fight of all-time. (Highlights)

Though Pacquiao repeatedly forced Mayweather to backpedal, the wily American blunted his opponent's best efforts by using his renowned defensive skills while getting in several telling jabs and punches of his own.

Mayweather and Pacquiao had promised to deliver on years of hype and give fans their money's worth and were true to their word in delivering an entertaining contest that had the capacity crowd on its feet roaring from the opening bell to the end of the 12 round showcase.

"Manny Pacquiao is a hell of fighter, I see now why he is at the pinnacle of boxing," the 38-year-old Mayweather said after an emotional embrace with Pacquiao. "I'm a smart fighter, I outboxed him.

"We knew what we had to do. He's a tough competitor... a very awkward fighter and I had to take my time and watch him closely."

The fight between the two greatest boxers of their generation was one that appeared might never happen as Pacquiao resisted Mayweather's demands for blood-testing for five years.

When the two camps finally hammered out a deal, it was the richest in boxing history, setting new records for pay-per-view (PPV) buys and gate receipts.

The fighters were also paid royally for their night's work, with Mayweather guaranteed $120 million and Pacquiao $80 million although both men could pocket much more depending on the number of PPV purchases.

For Mayweather, the fight was one that will shape his legacy.

Even if he were to have retired unbeaten there would have forever been a question mark hanging over his career without at least one meeting against his Filipino rival.

SEPTEMBER SWAN SONG

Mayweather said in the ring that he would fight again but that his next bout would be his last.

"My last fight is in September and then it is time for me to hang it up," Mayweather added. "I am almost 40 years old now, I have been in the sport 19 years, I have been world champion 18 years.

"I am truly thankful and I am blessed." (Pacquiao Believes He Beat Mayweather)

Dubbed the "Fight of the Century" the MGM Grand Garden Arena crackled with energy as the rich and famous settled into their ringside seats.

Actors Clint Eastwood, Robert De Niro, Mark Wahlberg and Denzel Washington rubbed shoulders with sports celebrities such as Michael Jordan, New England Patriots quarterback Tom Brady and billionaire Donald Trump.

With prime seats commanding six-figure sums on the resale market even the very wealthy and very famous were forced to call in favours to secure a golden ticket while an estimated 150,000 to 200,000 fight fans flooded into the desert gambling capital to be part of the buzz.

Wearing a simple white T-shirt, Pacquiao knelt in his corner for a prayer as boos filled the hall when Mayweather appeared on the giant screens.

There were no smiles from the stone-faced American as he entered the ring wearing black white and gold trunks and sporting a $23,000 mouth guard infused with flecks of gold and pieces of a hundred dollar bill.

Five years of hype then reached a climax when famed announcer Jimmy Lennon stood in the centre of the ring and told the crowd, "the wait is over, it's go time".

The bout marked Mayweather's 11th consecutive fight at the MGM but it was Pacquiao who enjoyed a massive edge in support as he appeared in the arena.

"It is a good fight. I thought I won the fight. He didn't do nothing. He always moved outside," said Pacquiao, who dropped to 57-6-2. "I did my best but my best wasn't good enough."
