Record holders Guadalajara crash to first defeat
Jaguars, the team from Chiapas, ended a winless run of 16 home matches at the Victor Manuel Reyna stadium dating back almost a year.
They dominated the Clausura championship match against a Guadalajara side who had already shown an astonishing loss of form last weekend in a lucky 2-0 home win over San Luis.
Striker Jorge Hernandez put Chiapas ahead after half an hour when he volleyed a clearance from outside the box into the top left corner of keeper Luis Michel's net.
Midfielder Edgar Andrade (pictured) increased the lead in the 55th minute from Jackson Martinez's pass and Christian Valdez scored the third in the 69th after being set up by Brazilian forward Danilinho.
Colombia striker Martinez completed the rout five minutes from time netting a cross from substitute Gerardo Flores.
Guadalajara remain way out in front of Group One while Chiapas are still bottom of Group Two after their first win of the championship.
Champions Monterrey, who lead Group Two, beat Pachuca 3-0 for their fifth win in succession.
