Copa Argentina: Arsenal 1 All Boys 1 (5-4 pens)
Arsenal have overcome All Boys 5-4 on penalties to set up a meeting with San Lorenzo in the Copa Argentina final.
After Wednesday's semi-final finished 1-1 after extra time, Arsenal recovered from Milton Caraglio's failed spot-kick - their second - as All Boys' Javier Campora and Jonathan Ferrari both missed.
The two misses sent Arsenal into the title decider as the Sarandi-based club continue their bid for a maiden cup triumph.
The Copa Argentina was relaunched two seasons ago after a 42-year hiatus and Arsenal will face another potential first-time champion in San Lorenzo - who were finalists in the unfinished tournament in 1970.
San Lorenzo drew 2-2 in the final with Velez Sarsfield but because a second leg was never played, a champion was never crowned.
In Wednesday's semi-final at the Estadio del Bicentenario in San Juan, Arsenal took the lead in the first half when Caraglio scored from the spot but All Boys equalised nine minutes after the break through Jonathan Calleri.
Neither side could find the back of the net for the remainder, nor after another 30 minutes of extra time.
Arsenal's Julio Furch scored the first penalty of the shootout and his effort was matched by All Boys' Exequiel Benavidez before Caraglio had his spot-kick saved by Nicolas Cambiasso.
Six successful penalties followed until Campora blasted All Boys' fifth over the bar.
With the shootout having reached the sudden death period, Damian Perez converted from the spot for Arsenal and the Sarandi outfit celebrated soon after as Ferrari also cleared the bar.
