On May 29, he won the WBA's "interim" world Super Flyweight championship by knocking out former WBO world Jr. Flyweight champion Josue Camacho in the fifth round at the Roberto Clemente Coliseum in San Juan, Puerto Rico. He was not generally considered to be a four division world champion, however, because the WBA had conditioned their recognition of him as world Super Flyweight champion on either one of two things happening: the real champion, Hideki Todaka, would have to decide to leave his place as champion or Gamez would have to beat him in a fight in order for Gámez to be recognized as champion. After losing the Flyweight crown on September 3 to Sornpichai Kratingdaengym by knockout in eight rounds at a Thai hotel, Gámez received an opportunity to solidify his status as WBA world Super Flyweight champion, when the official champion, Todaka, gave him a shot on October 9, 2000.
