Overview
San Isidro earned its place in the final after having won the 1912 Copa de Competencia Jockey Club, where the squad beat Estudiantes de La Plata (5–0 in Quilmes), Gimnasia y Esgrima de Buenos Aires (the match was not played due to Gimnasia had left AFA soon before to establish dissident FAF so San Isidro directly qualified to the final), and Quilmes (0–0 and 2–1, both games at Racing Club Stadium).

The final was held in Racing Club on November 17, 1912. The Racing field was chosen due to Gimnasia y Esgrima had disjoined the AFA under protest therefore the club would not allow the use of Estadio G.E.B.A. for the occasion. San Isidro scored on 12 minutes, when Alfredo Foglino kicked the ball out of the Nacional penalty area, but the rebound came to Costas that ran forward and shot to score the only goal of the match. In the second half, a penalty kick was awarded to Nacional but Costas missed the shot.

With this win, San Isidro won its first Tie Cup, taking revenge from the previous edition when the squad had lost to Montevideo Wanderers F.C.
