After 4 tournaments, and with the aid of its owner General Jose Manuel Nuñez (a retired militar asked personally by former President Lázaro Cárdenas to watch over the team) as well as of its sensational player Horacio Casarín, the team obtained its first championship in the 1946–47 season. The final match against León was attended by 48,622 people, including the current President Miguel Alemán Valdés (he even got into the field after the match in a famous photograph with the champions). Before that, in 1945 the team imposed the Latin American record for more goals in a single season with 121 goals in 30 matches (more than four goals per game). Atlante also became the first Mexican team to be crowned at the Champion of Champions cup (a "super cup" scheme championship) during the 1941–42 season.
