World ranked contender Abner Mares (18-0, 11 KOs) has joined forces with award winning manager Frank Espinoza. The 23-year-old Mares, promoted throughout his career by Golden Boy Promotions, is currently world ranked #4 by the IBF and WBO. The 2004 Mexican Olympian made his return from a detached retina injury after an almost one year layoff by stopping Jonathan Perez in the sixth round in Las Vegas on May 2nd. He is tentatively scheduled to return to action on the July 18th undercard of the Floyd Mayweather Jr. /Juan Manuel Marquez event at the MGM Grand in Las Vegas. Espinoza is best known for his outstanding handling of the career of junior featherweight world champion and “Pound for Pound” superstar Israel Vazquez, who incidentally will be announcing his future plans later this week.
