Banke would go on to lose the title by knockout against Pedro Ruben Decima, who in turn was knocked out by Kiyoshi Hatanaka. In 1991, Zaragoza regained the belt with a split decision win over Hatanaka in Japan. He defended the belt against Chun Huh (25-2-0) of South Korea and avenged his loss to Paul Banke. In 1992, he lost his title to Thierry Jacob by decision in France. In his next two fights he battled newly crowned WBC super bantamweight titleholder Tracy Harris Patterson, who had recently defeated Jacob. He fought to a draw with Patterson in the first bout and lost by technical knockout in the second bout when the fight was stopped due to a cut despite the objections of Zaragoza.
