Tijuana moved up to third in Mexico's Apertura as they beat Tigres 2-1 to end the visitors' unbeaten start to the season.
Alfredo Moreno and Fernando Arce gave the home side a two-goal lead by the 33rd minute and although Elias Hernandez pulled one back half an hour later, the hosts held on to join second-placed Leon on 10 points.
Leon themselves were held by Cruz Azul, with Luis Montes giving Leon the lead in the 70th minute, only for substitute Pablo Barrera to level soon after.
Friday's other game saw Morelia record a comfortable 3-0 win over struggling Puebla. Goals from Joao Rojas and Carlos Morales within the space of a minute just before the break had Morelia 2-0 up, with Miguel Sabah completing the scoring 13 minutes from time.
