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. 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.
