Juan Roman Riquelme scored twice to give Boca Juniors a 2-1 win over Racing Club and keep them top of the Argentine championship at the Bombonera stadium on Sunday.
Tigre moved into second place after coming from behind for a 3-1 win over River Plate who, incredibly, are bottom of the table.
San Lorenzo, previously second, dropped to fourth after their game against Huracan on Saturday was suspended by a torrential downpour in the 16th minute.
With two games to play, Boca lead the Apertura championship with 35 points from 17 games, two ahead of Tigre.
Riquelme opened the scoring with a 40th-minute penalty beating Pablo Migliore. Franco Sosa outjumped a group of Boca defenders to head Racing level in first-half stoppage time.
After becoming involved in an altercation with a supporter in the members' seats who apparently insulted him early in the second half, Riquelme volleyed the winner on the hour.
He then ran 50 metres to celebrate in front of the fan who became involved in a fight with other supporters around him.
