Tigres Monterrey kicked off their Apertura campaign with a 4-0 victory at Jaguares on Friday night.
The visitors had the game wrapped up by the interval, with first-half goals from Alan Pulido, Juninho, Lucas Lobos and Manuel Viniegra putting them firmly in control and they never looked likely to relinquish the healthy advantage.
Tijuana also started with a win, 2-0 at home to Puebla. Fernando Arce opened the scoring after 11 minutes and Pablo Aguilar put the result beyond doubt with a second goal 20 minutes from time.
