After another four-year absence on December 4, 1993, in "The Legend's Final Challenge" at the Mirage Resort and Casino in Las Vegas, Nevada, Urquidez fought Japanese champion Yoshihisa Tagami to establish the vacant WKA super welterweight world title. Despite having injured his left wrist in training, Urquidez proceeded with the bout and narrowly defeated his equally aggressive opponent with kicking attacks. Urquidez slipped to the canvas in round two; and Tagami scored a clean flash knockdown in round nine. Neither contestant was ever in serious trouble. The bout ended in a split decision, two judges scoring for Urquidez, one for Tagami.
