A fighting cowboy, a hometown hero, and the grandson of “The Greatest” are set for a summer night to remember in San Diego.

Mexican star Emanuel “Vaquero” Navarrete will defend his WBO featherweight world title in the main event against countryman Eduardo “El Gemelo” Baez on Saturday, Aug. 20 at Pechanga Arena San Diego. Navarrete also signed a new multi-year promotional agreement with Top Rank that will see him fight on the ESPN family of networks in events promoted in association with Zanfer Promotions.

The 10-round welterweight co-feature will see San Diego native Giovani “Gallo de Oro” Santillan risk his unbeaten record against a soon-to-be-announced opponent.

In a four-round special feature, undefeated middleweight prospect Nico Ali Walsh, grandson of Muhammad Ali, will fight Reyes Sanchez in a rematch of their December 2021 bout that Ali Walsh edged by majority decision. Ali Walsh will fight in the historic venue that hosted one of his grandfather’s most memorable bouts. In March 1973, Ali and Ken Norton battled for 12 rounds at what was then known as San Diego Sports Arena. Ali suffered a broken jaw and lost a split decision in a major upset.

Navarrete-Baez, Santillan’s welterweight battle, and Ali Walsh-Sanchez 2 will be broadcast live on ESPN, ESPN Deportes, and ESPN+ at 10 p.m. ET / 7 p.m. PT.
