The club got its nickname, the lepers, after playing in a charity match for a leprosy clinic in the 1920s. Liga Rosarina (1905–1930) On 30 March 1905, the Liga Rosarina de Football (Rosarian Football League) was established, following a proposal by Newell's president Heitz, who invited representatives of Rosario Athletic, Rosario Central and Atlético Argentino for that purpose. The main objective was to organise a championship, so a trophy was donated by the intendant of Rosario, Santiago Pinasco. The trophy was later named in his honour. Newell's was the winner of the first edition, having won eight games and finishing unbeaten. The team also scored 39 goals, conceding just 4. Previously, the historic first Rosarino derby had been held. Newell's won 1–0 with a goal scored by Faustino González. The next year Newell's won its second championship. In 1907, the Liga Rosarina established a second division. The Copa Santiago Pinasco tournament moved to that division and "Copa Nicasio Vila" (named in honour of then mayor of Rosario) was created to be played by the first division teams. Newell's won the first edition of this trophy, which they won a total 9 times between 1907 and 1930. The Copa de Honor Municipalidad de Buenos Aires allowed teams from Buenos Aires and Rosario to take part in the competition. Newell's won the 1911 edition defeating Porteño 3–2 at the final.

The AFA accepted the request, so Newell's played its first tournament in 1939, along with Rosario Central which was also added to the competition. Despite playing in the national tournaments, Newell's continued participating in the regional leagues of Rosario, but with youth amateur players. Newell's debuted in the AFA tournaments on 19 March 1939, defeating San Lorenzo by 2–1. The line-up was: Heredia; Gilli, Soneyro; Sisniega, Perucca, Reynoso; Belén, Fabrini, Gómez, Franco, Sánchez.
