Belgrano kicked off the new Torneo Apertura campaign with a comfortable 3-1 win over Nueva Chicago on Monday.
Sergio Escudero opened the scoring after four minutes, before Mauro Obolo doubled their lead 17 minutes later.
Ramon Lentini cut the deficit in half from the spot just before time to create nerves for Belgrano, who went down to 10 men in the 28th minute when Pier Barrios was sent off.
The visitors failed to make their numerical advantage count again after the break and they also had a man sent off in the 80th minute when Pablo Ruiz picked up a second yellow card before Lucas Zelarrayan added gloss to the scoreline for Belgrano in stoppage time.
Elsewhere, Estudiantes got their season off to a winning start away at Arsenal Sarandi as Israel Damonte scored the only goal in a 1-0 triumph.
