Banfield came from behind to enjoy a late 3-1 win over All Boys in the Argentinian Clausura.
All Boys had gone a goal up from a penalty in the fourth minute, Mauro Matos converting from the spot.
But Banfield hit back three minutes later when Facundo Ferreira equalised. They had to wait until seven minutes from time to take the lead, though, Marcelo Bustamante finding a way through before Gabriel Mendez eventually added the cushion of a third goal.
The day's other game, between Newell's Old Boys and San Lorenzo, was abandoned due to crowd trouble.
