Mexico produced the most one-sided victory, clobbering Paraguay, 6-0. New star Nery Castillo scored two goals, the first from the penalty spot in the fifth minute after Paraguay goalkeeper Aldo Bobadilla gave away a penalty and was sent off.
Argentina routed Peru, 4-0, on Sunday with all four goals coming in the second half -- two from playmaker Juan Roman Riquelme.
On Saturday, Uruguay ended host Venezuela's dream to reaching the semifinals for the first time with a 4-1 win in the weekend's only close game. The Celeste led by only a goal until it added two goals in the final three minutes.
Brazil thumped Chile, 6-1, to silence the critics of Coach Dunga for his defensive tactics in the first stage of the competition. Dunga uses three players -- Gilberto Silva, Josue and Mineiro -- who are considered defensive specialists in midfield. That may not sit well with fans back home, but Brazil was unstoppable against Chile.
"We never had a chance," said Chile coach Nelson Acosta.
