Meanwhile, Toluca goalkeeper Alfredo Talavera converted a late penalty to earn his team a 1-1 draw at Puebla.
Hector Mancilla settled the match between Morelia and second-bottom Unam Pumas with a 65th-minute strike which sent the visitors one point ahead of Club America and Leon, although America have two games in hand.
Talavera, meanwhile, coolly despatched an 89th-minute spot-kick to salvage a point for eighth-placed Toluca after Diego De Buen had given Puebla the lead in first-half stoppage time.
The day's other game also finished in a draw - 2-2 between Guadalajara and Tijuana. Marco Fabian's 82nd-minute equaliser nicked the point for Guadalajara, who had seen Hector Reynoso's 14th-minute opener overturned by goals from Aldo Polo and Fidel Martinez.
