Leading up to Juan Manuel Marquez's bid to win a world title in a fifth different weight class on Saturday, ESPN.com will look back at the elite group of fighters who have already achieved the feat -- we'll roll out a new one each day this week -- in our "Five In Five" series.
Floyd Mayweather Jr. has done it all in the world of boxing. He has beaten everyone he has faced and made hundreds of millions of dollars doing it. On May 5, 2007, Mayweather's official coronation as the king of the ring would take place.
That's the night he faced five-division world champion and reigning pay-per-view king Oscar De La Hoya. The fight was billed as "The World Awaits." De La Hoya was defending his junior middleweight title, and Mayweather was seeking to join him in the exclusive "five in five" club. Mayweather had already claimed world titles at 130, 135, 140, and 147 pounds.
In an action-packed fight that lasted all 12 rounds, the 30-year-old Mayweather scored a split decision victory and took his place among boxing's all-time greats.
He won the fight much as he had all of his others. He was extremely efficient in his offensive attack, landing 57 percent of his power punches (138 of 241). His overall connect rate was 43 percent, just above his career average of 42 percent. That's the best mark among active fighters, in case you were wondering.
The 34-year-old De La Hoya hoped to win rounds by being the busier the fighter. According to Compubox punch stats, the "Golden Boy" attempted 587 punches, 106 more than Mayweather. He landed just 122 of his attempts (21 percent). The strategy almost paid off, as judge Tom Kaczmarek scored the fight 115-113 in favor of De La Hoya. The other two judges, Jerry Roth and Chuck Giampa, saw the fight as most ringside observers did. Roth had it 115-113, while Giampa scored it 116-112, both in favor of Mayweather.
The fight generated a record 2.5 million buys and $136 million in pay-per-view revenue. The revenue record stood until Mayweather's most recent fight, against Canelo Alvarez. That fight produced $150 million from 2.2 million buys.
Mayweather hinted at retirement following the De La Hoya fight. He did step away from boxing for nearly two years following his December 2007 win over Ricky Hatton, then returned in September 2009 in a fight with Juan Manuel Marquez.
