Becerra received his first public notice in the Mexican sports world by scoring an upset over the vastly more experienced
Manuel Armenteros. After some ups and downs, Becerra earned a top 10 ranking by knocking out former world champion
Mario D'Agata. A short time later, Becerra won the
Undisputed World Bantamweight Championship with a knockout over
Alphonse Halimi. After two successful title defenses, Becerra lost a stunning upset, being knocked out by club-fighter
Eloy Sanchez in a non-title fight. Becerra was so dejected by the defeat that he announced his retirement at age 24. In 1962, Mexican club fighter,
Rudy Coronado was seriously injured in a fight. On a special benefit show for Coronado and his family, Becerra returned to the ring and won a 6-round decision over Alberto Martinez. Becerra donated his fight-purse to the injured boxer's family. Becerra never fought again. ==Professional boxing record==
