Indiscipline was at the highest order in Week 4 as a total of six red cards were shown in the nine games played this week. It was also the week of Andre-Pierre Gignac.
Juan Antonio Pizzi, who was announced as Chile manager earlier in the week, had a departure to forget as the Gignac scored a hat-trick to power TIgres past Leon at the Estadio Universitario.
The Frenchman got things going with a superb chip after only 11 minutes, and with the score at 2-1, culminated a brilliant first half by turning in a Rafael Sobis cross. The hat-trick was Gignac's first since arriving to Liga MX.
Pizzi wasn't the only one who had a Saturday to forget as Chivas suffered their first defeat of the season at the hands of Monarcas Morelia. Enrique Meza's side had remained winless in their previous three games, but thanks to goals from Pablo Velazquez and Juan Pablo "Chato" Rodriguez, the team from Michoacan clinched their first victory of the season.
Also clinching their first victory of the season was Cruz Azul. The Cementeros went down a man when Francisco "Maza" Rodriguez was sent off in the 20th minute. Silvio Romero then gave Chiapas the lead just before the half, but Cruz Azul fought back through goals from Daniel Benitez and Aldo Leao Ramirez to earn a heroic win at the Estadio Azul.
Sleeping at the top of the table is Pachuca. The Tuzos made it three straight wins after a resounding 3-0 win over Monterrey at the Estadio Hidalgo. After a scoreless first half, Franco Jara grabbed the breakthrough from the penalty spot before Ruben Botta and Rodolfo Pizarro made it 3-0 for the Tuzos. A late Rogelio Funes Mori goal served as a consolation prize for Monterrey, who suffered their first defeat of the season.
Elsewhere, Club America returned to winning ways by demolishing last-placed Dorados 3-0. Pumas UNAM and Puebla needed late goals against Atlas and Toluca respectively to rescue a point away from home.
Goal of the week: Juan Pablo "Chato" Rodriguez
