Boca Juniors forced a 2-2 draw in a heated clash against Godoy Cruz with an injury-time penalty by Claudio Perez to hold onto fourth spot in the standings, while River Plate and Belgrano drew 0-0.
Boca took the lead in the 31st minute via Emmanuel Gigliotti's neat goal but Godoy equalized seven minutes later when Gonzalo Castellani's cross was turned in by Jose Luis Fernandez.
Federico Lertora's effort from outside the area in the second half hit both posts but Mauro Ivan Obolo was on hand to turn the ball into the net to give Godoy a 2-1 buffer, which they held until the third minute of stoppage time when David Achucarro brought down Juan Manuel Martinez in the area.
At the final whistle both teams converged on each other as tempers flared.
