Vences and De Leon worked out for the media, Wednesday at Wild Card West Boxing Club, and discussed their upcoming bout.

Also appearing at the media workout were No. 3 WBO junior welterweight contender ALEX ‘El Cholo’ SAUCEDO (26-0, 16 KOs), former heavyweight title challenger ANDY RUIZ; 2016 U.S. Olympian MIKAELA MAYER; 2012 Brazilian Olympic silver medalist and middleweight contender ESQUIVA FALCAO (19-0, 13 KOs); and 140-pound contender ARNOLD BARBOZA, JR. (17-0, 6 KOs).

Saucedo will put his unblemished record on the line against the hard-hitting ABNER LOPEZ (25-8, 21 KOs) in a 10-round bout. Saucedo, from Oklahoma City, holds the WBO Latino belt and trains with Abel Sanchez’s stable in the mountains of Big Bear, Calif. He last fought on November 11, 2017, dropping Gustavo Vittori three times in the third round to force the stoppage.

Mayer (3-0, 2 KOs), will take on the rugged MARIA SEMERTZOGLOU (7-3, 2 KOs) in a six-round super lightweight bout. Mayer represented the United States at the 2016 Olympics, where she fell just one win short of advancing to the medal round. A Los Angeles native, Mayer will be making her StubHub Center debut against Semertzoglou, a two-time European title challenger who has never been knocked out.

Ruiz (29-1, 19 KOs), of Mexicali, Mexico, makes his ring return after a 15-month absence against DEVIN VARGAS (20-4, 8 KOs) of Toledo, Ohio. Ruiz last fought on December 10, 2016, when he lost a majority decision to Joseph Parker for the vacant WBO Heavyweight title.

Falcao (19-0, 13 KOs) will face SALIM LARBI (18-8-1, 5 KOs) of Brooklyn, New York.

And, in a 10-round crossroads battle of 140-pound contenders, Barboza Jr. will fight MIKE ‘Yes Indeed’ REED (23-1, 12 KOs).

The Valdez vs. Quigg world championship fight, along with Vences vs. De Leon, will be televised live and exclusively at 10:30 p.m. EST on ESPN and ESPN Deportes, and streaming live on the ESPN App. Additional undercard bouts will be shown on the ESPN App beginning at 7:35 p.m. EST.
