Emanuel "Vaquero" Navarrete (35-1, 29 KOs) makes the third defense of his WBO featherweight world title against Mexican countryman Eduardo Baez (21-2-2, 7 KOs), San Diego's undefeated welterweight contender Giovani Santillan (29-0, 16 KOs) looks to improve to 30-0 against Julio Luna (19-0-2, 10 KOs) in the 10-round co-feature, and Nico Ali Walsh (5-0, 4 KOs) grandson of Muhammad Ali, will see action in a four-round rematch versus Reyes Sanchez (7-2, 3 KOs). 

Ali fought at Pechanga Arena San Diego in 1973 — when it was known as San Diego Sports Arena — against Ken Norton in the first fight of their legendary trilogy. Norton broke Ali's jaw and won a decision in one of boxing's most storied upsets.

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