Pumas 1, Morelia 0
Pumas and Morelia were separated by three points entering Sunday but after the weekend's games were up, only one side stood the victor.
Francisco Palencia's goal gave Pumas a 1-0 victory that sent Pumas five points clear in the overall league standings as Pumas have 24 points. Tigres sit on 19 while Morelia and Cruz Azul are on 18 points.
Palencia's goal came in the second half as Leandro Augusto fed Palencia after a failed Morelia clearance on a corner kick. Palencia dived and re-directed the cross into the goal, despite protests that he was offside. The goal was his first in 11 months.
Morelia, meanwhile, raised the pressure on the visitors after the goal but Pumas held firm and did not give up much to Morelia.
