League leader Velez Sarsfield remains on course for the Argentine Clausura title after coming from behind to draw 2-2 with Racing Club at the Jose Amalfitani stadium on Saturday.
Racing went two goals to the good courtesy of strikes from Claudio Yacob and Ruben Ramirez, but Velez picked up a late draw with goals from Sebastian Dominguez and Victor Zapata.
