Universitario started to take part in official competitions in 1922, playing at the Unión de Rugby de Buenos Aires second division. The first official game was on May 15, 1921, when "CUBA" defeated Huemac by 11–0 in the Club Metropolitan field sited in Santos Lugares. Universitario won the championship without being defeated, therefore promoting to the top division of Argentine rugby. Only two players of that team had experience in playing rugby, Julio Dellepiane Rawson and Rodolfo de Surra (that had played in San Isidro and Eastbourne College of England, respectively).
