Mexico City's Estadio Azteca is known as an intimidating place for visiting teams. But it can be an intimidating place for visiting fans as well. To cut down on violence between spectators, fans of visiting teams are kept in what is known as "the cage." "The cage" is where most of the American fans sat Sunday night — a small speck of red, white and blue in a sea of green and red. Their team scored soon after, and the whole stadium rose up with an ecstatic roar, many people throwing full cups of beer into the air to celebrate.
