The 1920 Copa de Honor Municipalidad de Buenos Aires was the final that decided the champion of the 14th (and last) edition of this National cup of Argentina. In the match, held in Sportivo Barracas on January 30, 1921, Banfield won its first title in the top division after beating Boca Juniors 2âÂÂ1.
The 1925 edition was contested by 16 clubs, 14 within Buenos Aires Province and 2 from Liga Rosarina de Football participating in the competition. Playing in a single-elimination tournament, Boca Juniors reached the final after eliminating Sportivo Barracas (3âÂÂ0), Huracán (2âÂÂ0), Almagro (2âÂÂ0), and Newell's Old Boys (3âÂÂ2 in semifinal).
On the other side, Banfield had been eliminated by Almagro (then beat by Boca) in playoff 1âÂÂ0, but the disaffiliation of Lanús from the AFA caused the Association reprogrammed the competition. As a result, Banfield had a new chance, where the team beat Estudiantes de La Plata (unknown score), Sportivo Barracas (3âÂÂ1), Porteño (4âÂÂ0) and Tiro Federal (2âÂÂ1 in semifinal).
The final was held in Sportivo Barracas Stadium on January 30, 1921. Boca Juniors's Marcelino MartÃÂnez scored the first goal on 23 minutes, but Banfield finally won the match with goals of Pambrún and López, achieving its first title in the top division of Argentina.
