Overview
Boca Juniors beat Tiro Federal 2–1 in the final held in Sportivo Barracas. However, the Liga Rosarina claimed that three Boca Juniors footballers had played for other teams during that season (which was forbidden). Players pointed were Américo Tesoriere (for Sportivo del Norte), Felipe Galíndez (for Sportivo Barracas), and Marcelino Martínez (for Vélez Sarsfield).

On August 24, the Association decided that the score stood, proclaiming Boca Juniors as winner. Nevertheless, the Martínez case was still in doubt. Finally, in October 1921 both clubs agreed to replay the match. The Association accept that gentleman's agreement.
