Biography: Shane Mosley has been a terror in the ring since he laced up his first pair of gloves as a child.
The product of Pomona, Calif., who was blessed with an overwhelming combination of speed, power and fire, was an amateur star. He won national titles and competed in the 1992 Olympic trials, losing to Vernon Forrest.
Mosley is remembered mostly for his successes and failures at welterweight and junior middleweight but he was at his best at 135 pounds, at which he was untouchable. He was 32-0 – with 30 knockouts – before becoming a full-fledged 147-pounder.
That remarkable streak included eight successful defenses of the lightweight title he won by outpointing Philip Holiday in 1997 and victories over the likes of John John Molina, James Leija and John Brown.
“I think I was just too big for everyone,” Mosley said of his tenure at lightweight.
Stilll, he was known more by hard-core boxing fans than casual fans because he hadn’t taken part in high-profile fights against high-profile opponents. That would change shortly after he jumped from 135 to 147 in 1999.
Mosley faced superstar Oscar De La Hoya in his first megafight in 2000 in Los Angeles, winning a split decision to become a star in his own right and claim recognition as the best fighter in the world.
He ran his record 38-0 (with 35 knockouts) before he ran into trouble against amateur nemesis Vernon Forrest, who became the only fighter to put Mosley down (twice) en route to a one-sided decision loss in 2002 that cost Mosley is welterweight title. He did a little better in an immediate rematch but the result was the same.
Mosley rebounded with a second victory over De La Hoya, a controversial decision that gave him a junior middleweight title, but it was later learned that the winner had taken the performance-enhancing drug EPO leading up to the fight.
Then came more trouble. Mosley lost consecutive decisions to Winky Wright, a talented and naturally bigger man, during the worst stretch of his career. He was 1-4 (with one no-contest) between 2002 and 2004.
Since then, Mosley has had mixed results. He stopped Fernando Vargas twice and Ricardo Mayorga once but lost to Miguel Cotto and Floyd Mayweather Jr., and drew with Sergio Mora. He is only 8-6-1 since that 38-0 start.
However, before the Mayweather and Mora disappointments, the then-37-year-old also turned in one of his most-memorable performances: a spectacular ninth-round knockout over favored Antonio Margarito when many observers believed Mosley was in decline.
Was that the last hurrah of a future Hall of Famer?
