Abner Mares, who has won world titles in three weight classes, is the latest fighter to join the ever-growing stable of manager/adviser Al Haymon.
"I'm really excited and to be part of his team. I'm thrilled," Mares told ESPN.com. "The talks we had before I signed and the talks we had about the future ahead of me were great. I can't wait. I'm looking forward to it."
Mares (27-1-1, 14 KOs), 28, has won world titles at bantamweight, junior featherweight and featherweight. Last August, he was upset via first-round knockout by Jhonny Gonzalez, losing his featherweight title. Mares returned July 12 in Las Vegas, outpointing Jonathan Oquendo, and he is on track for another title opportunity.
"Any fight, Al and myself are open to," Mares said. "The one thing I like about Al and respect is before we made it official, we did talk to [Golden Boy Promotions] president Oscar [De La Hoya] and let him know we are working together. Oscar is open to work with us for any fight. You know me, my record speaks for itself. I'm not scared of anyone."
Mares said he remains under contract to Golden Boy until November, but that he will fight again this year.
"We're working on a date for November or December, but for sure another fight before the end of the year," Mares said.
Will it be with Golden Boy?
"It all depends on what we work out," said Mares, a 2004 Mexican Olympian, who has been with Golden Boy for his entire career and was the promotional company's first home-grown world titleholder.
Mares (27-1-1, 14 KOs) said he plans to stay at featherweight for the time being.
"My purpose now is to capture a world title again in this division," Mares said. "The way I lost, I feel pressure and obligated to myself to get that title back. Once I accomplish that, my intention is to move up and win another world title."
Mares said that he would like to face Gonzalez in a rematch but is open to fighting any of the other titleholders at 126 pounds. Those fights, however, could be difficult to make because Haymon and Top Rank do not work together, and the other titleholders, Nonito Donaire, Vasyl Lomachenko, Evgeny Gradovich and Nicholas Walters, are all promoted by Top Rank.
Whomever Mares will face next, he said he is doing some light training in Los Angeles, where he lives, but would make his way to the Bay Area next week for a two-week stay with trainer Virgil Hunter to work on some things.
Haymon has around 100 fighters in his stable, including many top fighters, such as Floyd Mayweather Jr., Marcos Maidana, Danny Garcia, Lucas Matthysse, Keith Thurman, Adrien Broner, Shawn Porter, Lamont Peterson, Deontay Wilder, Peter Quillin, Daniel Jacobs, Leo Santa Cruz, Devon Alexander, Chris Arreola, Rances Barthelemy, Andre Berto, Sakio Bika, Jermell Charlo, Jermall Charlo, Luis Collazo, Chad Dawson, Andre Dirrell, Anthony Dirrell, Omar Figueroa Jr., Andrzej Fonfara, Robert Guerrero, Amir Khan, Tomoki Kameda, Erislandy Lara, Josesito Lopez, Paulie Malignaggi, Beibut Shumenov, Adonis Stevenson and Austin Trout.
Mares joined Haymon after a five-year run with manager Frank Espinoza, who guided him to his three world titles.
"I hear people say I'm a traitor, that I sold," Mares said of leaving Espinoza. "I was with Frank for five years and the contract expired. We had success together, and we went our separate ways. I didn't do anything to get out of the contract. I completed my five years. I was a free agent and best deal wins, and the best move for myself was going with Al Haymon."
