Professional career
Espinoza turned professional in February 2013 and fought exclusively in Mexico until his bout against Ramirez. Espinoza survived a fifth-round knockdown and knocked Cuba’s Ramirez down in the 12th round to secure the WBO featherweight title by majority decision. One judge scored it 113-113, and the other two totalled 115-111 and 114-112 in Espinoza’s favour. In June 2021, Espinoza made a successful first defence against Sergio Chirino Sanchez, knocking his fellow Mexican down multiple times and out in round four.
