The main event will feature the first-ever world title unification fight in Costa Rica as IBF Minimumweight World Champion Yokasta “Yoka” Valle (25-2, 9 KOs) of San Jose, Costa Rica faces off against undefeated WBO Minimumweight World Champion Thi Thu Nhi Nguyen (5-0, 1 KOs) of Ho Chi Minh City, Vietnam in a 10-round bout.

The newly announced co-main event will feature a bad-blood rematch between WBC Interim Super Flyweight titleholder Sonia Osorio (15-7-2, 2 KOs) and undefeated challenger Adelaida “La Cobra” Ruiz (11-0-1, 6 KOs). The two will meet again after their first bout ended in a technical draw following an early stoppage that was due to a cut above Osorio’s left eye that was caused by an accidental headbutt.

Osorio captured the WBC Interim Super Flyweight title in October 2019 when she outboxed Estrella Valverde en route to a unanimous decision. She has faced top fighters such as Seniesa Estrada and Marlen Esparza and plans to retain her title for a second time against Ruiz.

“I’m very happy to once again fight against Adelaida Ruiz,” said Sonia Osorio. “It’s a fight that has been a long time in the making. Like always, I am working hard. I’m a professional, and I hope to deliver a great fight. I know it will be a great event, and I will retain my title because that’s why I have been training so hard.”

Ruiz’s only blemish is the technical draw against Osorio. The Los Angeles native immediately bounced back with knockout victories over Nancy Franco and Edith Flores. She is determined to become champion on Sept. 8.

“This fight means a lot to me,” said Adelaida Ruiz. “I’ve wanted this fight for more than a year. I felt like they took the title away from me when I fought her in Mexico, but God has given me another opportunity to fight for the title. It’s a big step forward in my career, and I’m willing to sacrifice everything to win. We are training very hard for this fight. Sonia will see a different ‘Cobra,’ both mentally and physically.”

The following undercard bouts are also scheduled to take place:

· Opening up the televised card, Angel “El Moreno” Rodriguez (11-1, 8 KOs) of Pico Rivera, Calif. will battle Ivan Delgado (5-0, 3 KOs) of Monterrey, Nuevo Leon, Mexico in a six-round lightweight bout.

· Raul “Money” Salomon (11-1, 9 KOs) of Long Beach, Calif. will return in a six-round super middleweight fight.
