Santos Laguna beat nine-man Leon 2-0 to edge closer to America.

Antonio Mohamed's America sits top with 17 points but has now failed to win any of its last three Apertura games and extends its goalless run to 265 minutes.

After Mauro Cejas' 10th-minute opener, Leon's task was made even tougher as Fernando Navarro received his second yellow card just before the half-hour mark.

Jose Maria Cardenas followed his team-mate's example 14 minutes from the end as he also saw red, and Jesus Escoboza wrapped up the win late on, squeezing a controlled effort past Christian Martinez in the visitors' goal.

Cruz Azul's unimpressive Apertura form continued as it was beaten 2-1 at home by Toluca, with the host having goalkeeper Jose Corona sent off at the death.
