TIGRES 4-0 JAGUARES
Olympic team reject Alan Pulido scored after seven minutes and Tigres never looked back. Eleven minutes later, Brazilian center back Juninho made it 2-0 for the away team.
Jaguares sorely missed Colombian striker Jackson Martinez, who left for Porto over the summer, as they couldn't muster enough offense to mount a response.
Juninho would make an impact on the scoreline once more, as he combined with Argentinian playmaker Lucas Lobos, who took the Brazilian's pass and struck for 3-0 after just 34 minutes. Tigres would close out their scoring in the first half with a goal from midfielder Manuel Viniegra.
TIJUANA 2-0 PUEBLA
Four Americans saw action at the Estadio Caliente as Xolos scored twice from set pieces to defeat Puebla. A well-struck free kick from Fernando Arce made it 1-0 after just 11 minutes.
In the second half, newly signed Paraguayan defender Pablo Aguilar took a corner kick and headed it past Alexandro Alvarez to shape the final score line.
American midfielder Joe Corona as well as defenders Edgar Castillo and Greg Garza played for Tijuana, while DaMarcus Beasley started for Puebla before coming off in the 20th minute after aggravating his tendinitis.
SAN LUIS 1-2 SANTOS LAGUNA
Herculez Gomez and Darwin Quintero brought Santos Laguna back from an early disadvantage as the reigning champion picked up an early road win against San Luis.
Emilio Lopez Navarro initially made it 1-0 for the Gladiators after only one minute of play, giving the home team a lead it would only enjoy for two whole minutes, as Colombian striker Darwin Quintero drew level, striking the ball right in front of the goal defended by Oscar Perez.
In the second half, Gomez broke through and gave Santos its first three points of the season, scoring in the 75th minute.
CRUZ AZUL 0-0 MORELIA
Perennial candidate Cruz Azul was held to a draw at home despite a revamped lineup that featured new signings Mariano Pavone, Luis Perea and West Ham castoff Pablo Barrera.
Morelia also began a new era under coach Ruben Omar Romano, who replaced longtime manager Tomas Boy. Cruz Azul was perhaps closest to breaking the scoreless draw when Pavone went wide in the first half despite being about three yards out.
QUERETARO 0-2 LEON
After 10 years of languishing in the Mexican second division, Leon came back in style and defeated relegation candidate Queretaro at La Corregidora for the club's first win since gaining promotion.
Hernan Burbano took a penalty after just three minutes to put the Emeralds ahead and give coach Gustavo Matosas satisfaction against his former employer. Tensions grew after Leon defender Juan Gonzalez was sent off after a questionable decision in the first half, but Leon was able to keep its lead.
Close to the death, Queretaro striker Carlos Bueno shot a penalty into the hands of Leon goalkeeper Edgar Hernandez. Minutes later, Edwin Hernandez broke through the home team's back line and struck it past Uruguayan netminder Juan Castillo to make Leon a winner.
MONTERREY 0-0 AMÉRICA
In a highly anticipated match, the defending CONCACAF champion was only able to draw with league giant América, which suffered elimination at the hands of Monterrey in last season's playoffs.
Humberto Suazo smashed a shot into the crossbar and Christian Benitez came close on two occasions, but goalkeepers Hugo Gonzalez and Jonathan Orozco were able to keep a clean sheet for each club.
Monterrey will be absent from Tuesday's Copa MX slate of games, as the club are exempt due to the fact that it will also play in the FIFA Club World Cup as well as the CONCACAF Champions League.
ATLAS 1-1 PUMAS
A dream debut for new manager Joaquin del Olmo was spoiled by his goalkeeper, as Alejandro Palacios allowed a late own goal to level hostilities between Atlas and Pumas at the Estadio Jalisco.
Martin Bravo opened scoring with a scorching shot from way outside the penalty area that put Pumas ahead 1-0 before the break.
Towards the end of the match, it would be Palacios' misfortune making it 1-1 only four minutes before the end of regulation. Atlas defender Facundo Erpen was sent off in injury time.
