Welcome to the Hex.
With its 3-1 home victory over Guatemala on Tuesday night, the United States men's national team qualified for the final round of CONCACAF World Cup qualifying—or the Hex as it's popularly known.
In the Hex, six teams will compete in home-and-home matches next year for three automatic berths to the 2014 World Cup (the schedule has not yet been released). The fourth-place finisher will enter a playoff with a team from Oceania for the region's final potential berth.
That means the U.S. has almost booked its place in Brazil. First, though, come the toughest tests yet. Here is a primer on the five opponents Jurgen Klinsmann's team must face in the Hex.
