MEXICO CITY, Jan 30 (Reuters) - Striker Americo Lopez scored twice to help Mexican champions Toluca beat San Luis 3-1 on Sunday and maintain their 100 percent start in the Clausura championship.
Uruguayan Vicente Sanchez opened the scoring at the end of a closely-fought first half and Lopez extended the lead with a second-half penalty and a well struck free-kick, sealing a second consecutive win for Argentine coach Americo Gallego.
Another Argentine, Ariel Gonzalez, seized on a defensive error to score San Luis' only goal of the game.
Toluca had overcome an early setback when goalkeeper Hernan Cristante retired with a neck injury after a clash with San Luis' Uruguayan striker Martin Liguera Lopez.
Pachuca came from behind to beat America 3-2 and remain level with Toluca in Group 2.
America's Brazilian striker Kleber Boas put his team ahead on eight minutes, but Ricardo Landin, Rodolfo Mosqueda and Richard Nunez replied with a goal apiece.
Boas' second goal of the game came too late to save America.
The 2-2 draw between Guadalajara and UNAM, on Saturday, provided the most thrilling action of the weekend.
The UNAM Pumas stormed into a 2-0 lead, with goals by Israel Castro and Bolivian Joaquin Botero.
Guadajara's record of 24 years without defeat at the hands of UNAM was under threat, but Ramon Morales and Edwin Borboa dramatically reversed the deficit with three minutes remaining.
