Top Rank presented by AutoZone: Navarrete vs. Valdez will be presented live this Saturday, August 12, at 10 p.m. ET/ 7 p.m. PT, on ESPN, ESPN Deportes and ESPN+ from Desert Diamond Arena, Glendale, Arizona.

In the main event, three-division world champion Emanuel “Vaquero” Navarrete will defend his WBO junior lightweight world title against former two-division world champion Oscar Valdez.

Navarrete (37-1, 31 KOs), the fighting pride of San Juan Zitlaltepec, Mexico, captured the WBO junior featherweight world title by defeating Isaac Dogboe in December 2018. After five defenses, he moved up to featherweight and defeated Ruben Villa for the vacant WBO title in October 2020. The 28-year-old defended his crown against Christopher Diaz, Joet Gonzalez and Eduardo Baez. In February, he became a three-division world champion with a ninth-round knockout victory over Liam Wilson.

Valdez (31-1, 23 KOs), from Nogales, represented Mexico at the 2008 and 2012 Olympics. The 32-year-old captured his first world title in July 2016 with a second-round stoppage win over Matias Rueda. In February 2021, he became a two-division world champion with a 10^th-round knockout against Miguel Berchelt. Valdez suffered his first loss to Shakur Stevenson in April 2022 and is coming off a unanimous decision victory against Adam Lopez in May.

The co-feature will showcase a 10-round junior welterweight tilt between rising contender Lindolfo Delgado (17-0, 13, KOs) and Jair Valtierra (16-2, 8 KOs).

U.S. Olympic silver medalist Richard Torrez Jr. (5-0, 5 KOs) will open the tripleheader in a special feature, six-round heavyweight tilt against Willie Jake Jr. (11-3-2, 3 KOs).
