From WBC:
Valverde and Osorio fighting for WBC Interim Crown
Estrella Valverde and Sonia Osorio will fight on October 25 in Texcoco de Mora, State of Mexico, for the female interim WBC title of the super-fly division.
Estrella says a win is a must, as her prime ambition for 2020, is to win the absolute world title of the division that Guadalupe Martinez possesses.
Yet Sonia is also a highly disciplined fighter and since she began her professional career in 2013, her aim is directed towards… exactly the same goal.
