Uruguay eliminated Mexico from the Copa America Tuesday to set up a mouth-watering quarterfinal clash with Argentina, while Chile finished top of Group C after a 1-0 win over Peru. Mexico, which was effectively fielding an under-22 side at the Copa, exit the competition after three consecutive losses. Chile topped the group, with Uruguay in second place and Peru third. All three sides progress to the quarterfinals, although Chile and Peru will have to wait until Wednesday to find out who they face next. World Cup semifinalists Uruguay, having drawn their opening two matches, took the lead through Alvaro Pereira after 14 minutes, the midfielder taking advantage of a deflection from a Diego Forlan free kick to bury the loose ball from close range. The Uruguayans dominated much of the match but failed to add to their score. Forlan hit the inside of the post with a low shot in the 30th minute and it was only in the final 20 minutes that Mexico turned up the heat. They appeared to have equalized in the 89th minute through Rafael Marquez but his effort was ruled out for offside. The Uruguay-Argentina quarterfinal pits the two most successful teams in the Copa America against one another. Both teams have won South America's most prestigious competition 14 times. Chile, looking to win the competition for the first time, needed a 92nd minute own goal from Andre Carillo to beat a stubborn Peruvian side in Mendoza. Carillo inadvertently bundled the ball into his own net after a scramble in the six-yard box from a corner. The result means Chile will play whoever finishes second in Group B in the quarterfinals in San Juan. That could be Brazil, Paraguay or Venezuela.
