WBO and IBF minimumweight titleholder Yokasta Valle wants to make history for Costa Rica, but standing in her way is a fellow pound-for-pound dynamo for whom this rivalry has become personal.

Valle is set to face WBC, WBA and Ring Magazine titlleholder Seniesa “Super Bad” Estrada in an undisputed minimumweight showdown on March 29 at Desert Diamond Arena in Glendale, Arizona (streaming exclusively on ESPN+ in the U.S.).

“This fight is very important because becoming undisputed champion is a dream of mine, and because I’d be making history for Costa Rica and for all Latinos,” Valle said. “It’s also important because of the many years of effort in putting women’s boxing where it is now.”

Estrada-Valle will serve as the co-feature to the 12-round junior lightweight main event between former two-division titlist Oscar Valdez and one-time title challenger Liam Wilson.

Valle (30-2, 9 KOs) claimed the vacant IBF atomweight title by defeating Ana Victoria Polo in December 2016. Nearly three years later, in August 2019, she moved up in weight to take the IBF minimumweight belt from Joana Pastrana. Valle added the WBO title to her collection with a victory over Thi Thu Nhi Nguyen in September 2022. She has defended her unified crown four times since, including most recently in a decision win over Anabel Ortiz in November.

"You will see the best version of me in this fight,” Valle said. “I’m aggressive, and I’m a warrior. When the bell rings, I like to throw lots of punches. So you will see a Yokasta who is very aggressive and who will throw lots of punches, to the point where she won’t know where they are coming from.”

Estrada (25-0, 9 KOs), a 13-year pro and two-division titlist, is seeking to end a longstanding rivalry by fully unifying the division. Valle works with Gloria Alvarado, who has known Estrada for years. She warns her opponent not to get distracted. 

“If she’s not concentrated on this fight,” Valle said of Estrada, “and is thinking about other things that have nothing to do with it, then it can be to my advantage.

“My coach knows her really well. But aside from that, I have an advantage because she is also an excellent trainer. It’s because of that and not because she’s known her since she was a kid. She knows how to work with me. We have a great connection.”
