America overcame two expulsions and defeated the heretofore unbeaten Tijuana to temporarily take the lead in the sixth week of Mexico's Clausura 2013 soccer tourney on the weekend.

Although Argentina's Rubens Sambueza was red-carded in minute 23 of the Saturday match and Colombia's Aquivaldo Mosquera was expelled in the 37th minute, that wasn't enough to prevent America from securing a 2-1 victory away from home. The result temporarily put America in the No. 1 spot in the tourney, although the team was deposed on Sunday with the Tigres' win over Toluca.

Paraguayan Osvaldo Martinez had scored for America in the 12th minute on a penalty kick, and Paul Aguilar found the net in the 53rd minute to put America up 2-0, although Tijuana saved face by launching an attack that resulted in its lone goal by Pablo Aguilar, also from Paraguay.

It was Tijuana's first loss at home since May 2012 and broke its streak of 10 consecutive wins and 3 ties at the Caliente stadium, and the defeat knocked the team down to third place, after America and Tigres.

Meanwhile, the Guadalajara Chivas won their first match in the tourney under the direction of Benjamin Galindo on a lone goal by Mexico's Rafael Marquez Lugo at home over the Monterrey Rayados.

The sixth week of the Clausura 2013 began on Friday with Morelia's 1-0 victory over Leon, and the 1-1 ties between Cruz Azul and Pumas UNAM and also between Queretaro and the Chiapas Jaguares on Saturday.

Atlas downed Atlante 2-1, also on Saturday, its third victory of the tourney, and Puebla beat San Luis 3-1 in an away match.

And on Sunday, the Tigres trounced Toluca 4-1, retaking the tournament leadership slot from America, with Santos to play 10th-ranked Pachuca later in the evening. EFE
