RENO, Nev. (May 30, 2019) — Gabriel Flores Jr., the 19-year-old pride of Stockton, California, had the night of his boxing life May 4 at Stockton Arena. More than 10,000 fans packed the venue, as Flores knocked out Eduardo Pereira Reis in three raucous rounds, establishing himself as the sport’s youngest hometown ticket-seller.

Flores will return June 8 against Salvador Briceno in an eight-round lightweight bout, which will be the ESPN-televised co-feature to Oscar Valdez’s WBO featherweight world title defense against fellow unbeaten Jason Sanchez at Reno-Sparks Convention Center.

Valdez-Sanchez and Flores-Briceno will be televised live on ESPN and ESPN Deportes beginning at 10 p.m. ET/7 p.m. PT.

The entire undercard will stream live on ESPN+, the leading multi-sport streaming service, beginning at 6:30 p.m. ET/3:30 p.m. PT.

“I am excited to be back on ESPN, and once again, Stockton will be in the building,” Flores said. “Briceno is the toughest fight of my career, but I rise to the level of my opposition. I only fought a few weeks ago, so I am sharp and ready to put on another highlight-reel showing for the fans watching on ESPN.”

“Trust me when I say that Flores has never faced anyone like me,” Briceno said. “I am coming to Reno intent on putting on a great performance. Flores probably thinks I am a stop on the way to bigger things, but his team made the wrong decision in picking me.”

Flores (13-0, 6 KOs) signed with Top Rank at 16 years old and made his pro debut on May 5, 2017, four days after his 17^th birthday. His pro debut took place at the Reno-Sparks Convention Center, a second-round TKO over Devon Jones. Flores went 6-0 in 2018 and will be making his third ring appearance of 2019. Briceno (15-3, 9 KOs) has fought as high as 140 pounds and is a heavy puncher whose last four victories have come via stoppage.

The ESPN+ undercard is scheduled to include the following bouts:

• Andy Vences (22-0-1, 12 KOs), one of the super featherweight division’s top contenders, will defend his WBC Continental Americas belt against fellow unbeaten Albert Bell (14-0, 5 KOs) in a 10-rounder that will thrust the winner into the world title conversation. Vences has made no secret of his desire to fight newly minted WBO champion Jamel “Semper Fi” Herring.

• Robson Conceicao (12-0, 6 KOs), who captured Brazil’s first Olympic boxing gold medal at the 2016 Rio Olympics, will take on Carlos Ruiz (16-6-2, 6 KOs) in an eight-round super featherweight bout. Conceicao last fought March 31 in Mangaratiba, Brazil, where he scored a first-round TKO.

• Diego Elizondo (2-0-1, 0 KOs), who hails from Carson City, Nevada, will look to get back in the win column versus Sacramento product Sergio Vega (2-0, 2 KOs) in a four-round lightweight shootout.

• Big-punching light heavyweight Michael Seals (22-2, 16 KOs) will fight Philadelphia native Christopher Brooker (14-6, 5 KOs) in a 10-rounder. Brooker is coming off an upset win over Lanell Bellows (18-2-2 at the time) last September in Las Vegas.

• Reno native J.J. Mariano will make his pro debut in a four-round welterweight contest against William Flenoy (pro debut),

• Dmitry Yun, a former Russian amateur standout, will make his pro debut in a six-round lightweight bout against an opponent to be named.
