Brazil thrashed Chile 6-1 to go through, while Uruguay humiliated hosts Venezuela 4-1 at the Pueblo Nuevo Stadium in San Cristobal.

Brazil, inspired by the competition's top scorer Robinho, ended the first half with a comfortable 3-0 score line, which resembled their group stage win against the Chileans.

Defender Juan opened the scoring after 14 minutes, Julio Baptista added the second in the 16th minute, and Robinho made it three four minutes later.

Josue made it five in the 38th minute, and Vagner Love completed the drubbing five minutes from time after Humberto Suazo's consolation for Chile.
