Julio Cesar Martinez (El Rey) boxer

Julio Cesar Martinez Aguilar (born 27 January 1995) is a Mexican professional boxer who has held the WBC flyweight title since 2019.As of June 2021, Martinez is ranked as the #1 flyweight boxer in the world by BoxRec, The Ring and TBRB, while ESPN ranks him as the #2 flyweight in the world.Martinez made his professional debut against Joaquin Cruz on October 16, 2015. He lost the fight by a split decision. He would go on to amass a 13-1 record over the course of his next 13 fights.Martinez was scheduled to fight Andrew Selby on March 23, 2019, in a WBC Flyweight title eliminator to determine the next mandatory challenger. Martinez won the fight by a fifth-round knockout, handing Selby the first loss of his professional career. Selby had a great start to the fight, before a clash of heads in the third round cut him along his left eyebrow, for which Martinez was deducted a point. Martinez enjoyed more success from the third round onward, knocking Selby down with a liver shot 57 seconds into the fifth round.As Martinez had secured his position as the mandatory WBC flyweight title challenger with the fifth-round knockout of Andrew Selby, WBC ordered the reigning flyweight world champion Charlie Edwards to defend his title against Martinez. They were later given a weeklong extension from the sanctioning body to come to terms as regards the purse and venue. The two parties avoided going to a purse bid, agreeing to fight at the The O2 Arena in London, on the Lomachenko vs Campbell undercard, on August 31, 2019.
