A 1996 Olympic Bronze medalist for the United States, Floyd "Money" Mayweather (39-0, 25 KO's) has since gone on to strike Gold in the professional ranks, winning six world titles in five weight classes to firmly establish himself as one of the best fighters of his era.  In just his 18th pro fight, Mayweather won his first world title at the age of 21 by stopping Genaro Hernandez for the WBC world super featherweight crown in 1998.  The Grand Rapids, Michigan native defended that title eight times before moving up to lightweight and taking the 135-pound belt from Jose Luis Castillo in 2002, but "Money" Mayweather wasn't done yet, as he defeated Arturo Gatti and Zab Judah for the junior welterweight and welterweight world titles, respectively.  Despite these impressive achievements, it wasn't until he defeated Oscar de la Hoya in May of 2007 for the world junior middleweight championship in a record-setting super-fight where the world truly got to see what Mayweather was all about.  In his last fight, on December 8, 2007, Mayweather made another statement to the world when he knocked out Ricky "Hitman" Hatton in the tenth round, handing the British superstar his first professional defeat.  After the bout, Mayweather - who has achieved crossover fame as a contestant on the hit show "Dancing with the Stars" and as a participant in WWE's "Wrestlemania XXIV" - announced his retirement from boxing.  But he left the door open for a return if the right challenge presented itself, and on July 18th, the 32-year-old Las Vegas resident comes back to face Juan Manuel Marquez.

In an era of great Mexican fighters such as Marco Antonio Barrera and Erik Morales, Mexico City's Juan Manuel "Dinamita" Marquez (50-4-1, 37 KO's) has made it clear over the last few years that he is truly the greatest of the bunch.  Long revered by boxing purists as one of the best, Marquez won 29 of his first 30 pro bouts, before finally getting a world title shot in 1999.  Marquez would lose that opportunity controversially to Freddie Norwood and in response, he didn't lose for the next seven years, winning the IBF world featherweight title against Manuel Medina in 2003.  In November 2003, Marquez unified the titles when he defeated Derrick "Smoke" Gainer and captured the WBA world featherweight title.  His second title defense in 2004 against Manny "Pacman" Pacquiao may be his most memorable, as he rose from three first-round knockdowns to roar back and gain a draw in a fight that many observers believe he won.  Marquez would lose his belt via decision to Chris John in 2006, but he returned to form almost immediately, scoring a 12-round win over Barrera in March of 2007 to win the WBC 130-pound world title.  In 2008, Marquez and Pacquiao would meet again in another memorable bout however Marquez dropped a disputed 12-round split decision to the Filipino superstar.  Undeterred, "Dinamita" moved up to the 135-pound weight class in September of 2008 and stunned the boxing world by handing Joel Casamayor his first knockout defeat to win the Ring Magazine world lightweight championship.  It was hard to top such a victory, but in the 35-year-old Marquez' most recent fight on February 28, 2009, he did just that as he stopped former Three-Time World Champion Juan Diaz in the ninth round to add the WBO and WBA World Lightweight belts to his trophy case.  On July 18th he looks to further cement his legacy with a win over Mayweather.
