Julio Cesar Martinez to defend flyweight title on Feb. 29

Julio Cesar Martinez will make his first title defense against Jay Harris on a Feb. 29 card featuring the Mikey Garcia-Jessie Vargas bout.

Julio Cesar Martinez didn’t celebrate for long. He introduced himself as a flyweight champion in December and he will fight to validate his sudden place alongside the other 112-pound champs with a title defense in February.

Martinez (15-1, 12 KO) will make his first title defense on Feb. 29 against Jay Harris (17-0, 9 KOs) of Wales on a DAZN card featuring the Mikey Garcia-Jessie Vargas welterweight bout in Frisco, Texas, it was announced this week.

Martinez got the only cheers on a card remembered for the debris tossed at Julio Cesar Chavez Jr. on Dec 20 in Phoenix. Martinez displayed power and poise, winning a ninth-round TKO of former champion Cristofer Rosales, a Nicaraguan who had never been stopped.

“I’m so happy to be back fighting so soon,’’ Martinez said. “It was a special moment to become world champion but now I must continue to work hard.’’

In part, the 24-year-old Martinez, of Mexico City, is staying busy in an attempt to gain some name recognition.

“It’s perfect to have Julio back fighting so quickly,’’ said Martinez trainer Eddy Reynoso, who also trains Canelo Alvarez. “It’s all part of developing him as a fighter.  He has so much potential, and I believe he is going to dominate and unify the division in time.’’

Despite Martinez’s new found title, Harris has a better record. The Welshman is unbeaten (17-0, 9 KOs). He scored a fourth-round stoppage of three-time Olympian and two-time bronze medalist Paddy Barnes on Oct. 11 in Belfast, Northern Ireland.

“Julio is a great young fighter,” Harris said, “but I am feeling in the form of my life and this gives me the opportunity to shock the world.”
