Career
It is said that such bout catapulted Chavez's career. Mario Martínez became a professional boxer at the age of 16 in his native Guadalajara, Jalisco. His victory against Navarrete earned him a shot against Julio César Chávez for the vacant WBC Super Featherweight title on 13 September 1984.
In that fight, staged at the Grand Olympic Auditorium in Los Angeles, California, Chávez knocked him out. A year later, in 1985, he lost a close decision to Roger Mayweather. Later on, he was beaten by Azumah Nelson (twice), Jeff Fenech and Dingaan Thobela.
Martínez retired at the age of 31.
