Juan Roman Riquelme and Lionel Messi were the stars for Argentina, which improved its tally to 16 goals in five games.
Riquelme set up Gabriel Heinze for the first goal in the 45th minute and scored the third goal from the penalty spot. Messi broke the game open when he spotted Mexico goalkeeper Oswaldo Sanchez off his line and chipped the ball into the net.
Mexico had its chances. The Tri's two youngest stars, Andres Guardado and Nery Castillo, both hit the woodwork.
