This began a late-career surge for Zaragoza who was able to defend the title four times, including two wins against former and future champion Joichiro Tatsuyoshi in Japan, a tko win over Tsuyoshi Harada (20-1-0) also in Japan, and an upset win against undefeated bantamweight champion Wayne McCullough who had recently moved up in weight. On Sep 6, 1997, he lost his title to then-undefeated 21-year-old Erik Morales, who knocked out Zaragoza in the 11th round. Zaragoza retired after the bout at the age of 39 with a record of 55-8-3.
