A lot of people already knew that Jesus Padilla had Mexican and U.S. citizenship. Yet it's not enough for Club Deportivo Guadalajara to field only Mexican citizens. The standard for the club has long been that all their players had to be Mexican-born. Heritage and naturalization isn't enough. Yet at least two other players have played for the Jalisco club who were not born in the country.
Gerardo Mascareño was one. He played in ten games for the club in 1998 and scored a goal. However, club directors were apparently under tremendous pressure from fan groups not to play Mascareño because of his U.S. birth. He was traded to Pachuca.
An earlier player lasted years with Chivas, though rumors circulated for a long time that he was born in the U.S. Eduardo Fernández de la Garza managed to stay on for four seasons with Guadalajara, though birth records in Texas state he was born there.
Though many people consider Gabriel Caballero to be the first naturalized player for the Mexican national team, Mascareño appeared for El Tri years before. He played the second half of an international friendly versus Ecuador on Oct. 23, 1996, back when Bora Milutinovic ran the squad.
