Fighting out of his native San Diego, Chollet (7-0, 6 KOs) went the distance for the first time as a pro the last time he entered the ring, scoring a shutout of Daniel Perales in May. The 21-year-old has already fought three times in 2023 and will step up in competition when he faces Hayward, California’s Portales (3-1-1, 1 KO). The 26-year-old Portales bounced back from his first career defeat, which took place in February, to earn a unanimous decision over Margarito Hernandez in April.
The 18-year-old Viloria (2-0, 2 KOs) turned pro in April and has delivered a pair of stoppages in each of his first two matchups. The Whittier, California-native most recently stopped Pedro Pinillo in four rounds in May. He’ll step in against the 18-year-old Borgaro (4-0, 2 KOs), who represents Sonora, Mexico and made a successful U.S. debut in July by stopping Martin Cardona in two rounds.
The 20-year-old Zamora (11-0, 9 KOs) turned pro in 2019 as a teenager and delivered knockouts in eight of his first nine matchups. The Las Vegas-native has fought in his hometown twice previously as a pro, including his most recent outing that saw him KO Jesus Ibarra in March. He will be opposed by the Brooklyn-based Buzolin (9-4-1, 5 KOs), who’s only defeats have come against previously unbeaten fighters. In his last fight, Buzolin knocked out Gonzalo Carlos Dallera in three rounds in July 2022.
A training partner of Terence Crawford, Ventura (11-0, 8 KOs) fights out of Omaha, Nebraska and will compete in Las Vegas for the first time as a pro on July 29. The 26-year-old returned to the ring off of a four-year layoff in September 2022, emerging victorious via unanimous decision over Gilbert Venegas. He will face the 25-year-old Prather (15-1, 2 KOs), who made a successful 2023 debut by earning a decision over Brandon Clark in February. The Kansas City, Missouri-native turned pro in May 2018 and is unbeaten since a one-point decision loss in his second pro fight.
