Former world champion Yokasta Valle from Costa Rica will return to the ring to face Mexico's Elizabeth Lopez for the vacant WBC minimumweight title today (November 1st) at the Liberia Chamber of Cattle Ranchers in Guanacaste, Costa Rica. The belt became vacant when Valle's conqueror, undisputed world champion Seneisa Estrada, retired last month. With a record of 31-3, with 10 knockouts, Valle will face Lopez in an event that will mark the path that Valle will have to follow if she intends to establish herself as the best in her division. Lopez, age 31, is from Chiapas, Mexico. Better known as “La Veneno,” Lopez has a record of 11 wins, 6 losses and 5 draws in the ring, with moslty low-level wins. This Thursday both fighters passed the official weigh-in. Valle registered 104.7 pounds, while Lopez was 106 pounds (the WBC allows a pound of tolerance at the official weigh in, considerating the effects of the menstrual cycle). On this same card, Yokasta’s sister, Naomy Valle, will also be in action when she faces Venezuela's Erika Bolivar. The fight is presented by Sport Boxing Promotions, in association with Golden Boy Promotions, and will be broadcast on ESPN KO.
