The United States travelled to the Azteca Stadium in Mexico to face its familiar rivals.
When former captain Carlos Bocanegra wasn't called up to the United States squad, people thought Juergen Klinsmann was making a huge mistake, but Klinsmann clearly had a plan.
Although the back line was young and inexperienced, it did not show for the most part.
In the snowstorm game against Costa Rica, a game that almost required mistakes to be made, the defense was solid. Sure there were a few hiccups here and there but nothing cost the team.
Then came the much anticipated game against Mexico.
Klinsmann was asking a lot of his young defenders. He even threw in Matt Besler who only had one previous cap.
But the defense did not let him down. Despite DaMarcus Beasley's few slip-ups, everyone on the back line was solid and played a good game.
Even though Team USA was also without star goalkeeper Tim Howard, the team conceded no goals this international break. Brad Guzan was impressive.
This has to be considered a successful round of World Cup qualifiers for the Americans. This new defense may be a good sign for the future.
