Estudiantes beat Argentinos Juniors 3-1 on Saturday and closed in on the Argentina Apertura title.
Ciro Rius scored in the 31st minute for Argentinos and Gaston Fernandez equalized in the 36th.
Maxi Nunez banged in a 12-meter (yard) shot in the 58th minute to break the tie, and Gabriel Mercado made it 3-1 in the 75th.
Estudiantes has 39 points with two matches remaining. Second-place Velez plays on Sunday against Godoy Cruz and could improve to 37 points with a victory. In the next two rounds, Estudiantes face River Plate and Arsenal, and Velez has Huracan and Racing.
"We played as hard as we could and you cannot ask more of a team," Fernandez said.
The only bad news in the match was an early yellow card for Estudiantes playmaker Juan Sebastian Veron. Veron picked up the card after protesting a call and will miss the next match.
Also Saturday, River Plate rallied for a 2-1 victory over Colon behind second-half goals from Eric Lamela and Francisco Pavone. Pavone scored the winner in the 4th minute of second-half stoppage time, connecting from 8 meters (yards) after a defensive mix-up in front of the net.
