Alfonso Zamora

Zamora never seemed to recover from this loss. In his next fight he lost his Lineal and WBA Bantamweight titles to Jorge Luján by knockout in the tenth round. His record thereafter was spotty, and he even was stopped on 16 November 1979 by Eddie Logan, who sported a record of 5 wins and 7 losses. He retired after losing, again by knockout, to Rigoberto Estrada on 19 September 1980. In 1983, Zamora was to fight Wilfredo Gómez, the fight ultimately was canceled.

Fighting contemporaneously, and holding the WBC crown, was the fellow-Mexican legend, Carlos Zárate Serna. A showdown between the two was inevitable and they met in a non-title match on 23 April 1977. Zamora went into the bout sporting a record of 29 wins in 29 fights, all by knockout. Zarate's record was an equally impressive 45 fights, 45 wins, with 44 KOs. In a largely anticipated fight Zarate scored a technical knockout over Zamora in the fourth round.

He won the Lineal and WBA Bantamweight title on 14 March 1975 when he knocked out Soo-Hwan Hong in four rounds, two years after turning pro. Zamora defended his title twice that year via knockout, against Thanomchit Sukhothai and Socrates Batoto. On April 3, 1976, he knocked out future hall-of-famer Eusebio Pedroza in the second round. Later that year, he successfully defended his title via knockout against Gilberto Illueca and a rematch with Soo-Hwan Hong.
