Although the city of Rosario did not have an organised league, since 1900 the football squads of Rosario A.C. and Rosario Central had taken part of the first international tournament in South America, the Tie Cup, played by teams of Rosario, Buenos Aires and Uruguay leagues. Rosario A.C. became the first Rosarian team to win an international competition after winning the cup in 1902, defeating legendary Alumni 2–1 in the playoff match. The squad would win two cups else, in 1904 (beating Uruguayan CURCC 3–2) and 1905 (winning over CURCC again by 4–3) editions, totalling three championships in six years.
