Do not expect an open, expansive affair at Stadion Omar Higinio Sperdutti. Both sides have shown a tendency to keep things tight — Deportivo Maipu frequently edge their home games by a narrow margin, and San Martin Tucuman have found the net in fewer than half of their away matches this season. The likely narrative here is a disciplined, attritional contest decided by a moment of quality rather than a goalfest. Our engine forecasts a home win for Deportivo Maipu at 42% probability, with the scoreline almost certainly a narrow one.
