Daniel Ponce De Leon retires

Former two-division titleholder Daniel Ponce De Leon announced his retirement from boxing Tuesday in the wake of a ninth-round knockout loss to Mexican countryman Mickey Roman on Saturday night in their hometown of Chihuahua.

"Thanks to each and every one of my fans and friends who supported me throughout the course of my career," Ponce De Leon wrote on his Facebook page. "I retire with a great taste for all the great moments. I will search for new goals. God bless you all."

The 33-year-old Ponce De Leon (45-7, 35 KOs), one of boxing's heaviest hitters, was a significant fighter for several years. He claimed a vacant junior featherweight world title by unanimous decision against Thailand's Sod Kokietgym in October 2005 in Tucson, Arizona. Ponce De Leon, who turned pro in 2001, made six successful defenses before he lost the belt with a stunning first-round knockout loss to Juan Manuel Lopez in June 2008 in Atlantic City, New Jersey.

In September 2012 in Las Vegas, Ponce De Leon got a shot at a featherweight belt and won it by eighth-round technical decision against Jhonny Gonzalez. However, he lost the title in his first defense when he was stopped by Abner Mares in the ninth round in May 2013 in the co-feature of the Floyd Mayweather Jr.-Robert Guerrero welterweight title fight in Las Vegas.

Ponce De Leon, a southpaw, returned for a victory in Mexico in November, but then lost his next two fights, getting stopped in the second round of a rematch with Lopez in Puerto Rico followed by Saturday's loss to Roman, who dropped him in the sixth round en route to the stoppage.

Besides fighting, Ponce De Leon, who lives in Southern California, has worked recently as a Spanish-language television commentator and has been training fighters.
