The most important tournament for the U.S. men's national soccer team is the one that kicks off this weekend, the one that gives the U.S. the right to go to the World Cup in the first place.
It's known by a simple name: the Hex.
It includes the final six teams from CONCACAF qualifying (hence hexagonal). The top three qualify for the World Cup. A fourth goes to a difficult, pressure-packed playoff against an African team.
Anything but a top-three spot will be a failure for the United States. But you don't have to go back very far — 27 years this week, in fact — to find a time when American World Cup qualification seemed all but impossible.
In 1989 the United States hadn't been to a World Cup since 1950, and in most years hadn't come close to qualification. Five CONCACAF teams were competing for two spots in the 1990 World Cup. For once, though, the Americans were optimistic. Mexico, the perennial favorite, was banned for fielding an ineligible player in a youth tournament. The Americans were riding a wave of young talent and were positioned to qualify.
But after the United States blew an easily winnable match at home, everything came down to one final game at Trinidad and Tobago, where the home side hadn't lost a single game in qualifying. Anything but a victory and the Americans were staying home yet again from the World Cup.
To add to the pressure, there were rumors that FIFA was rethinking its decision to award the 1994 World Cup to the U.S. If the Americans couldn't qualify in 1990, the rumors said, FIFA might decide that the country wasn't ready to host the whole tournament.
Enter Paul Caligiuri, a defender who was playing in midfield that day. A half-hour into the game, Caligiuri received the ball in space in the opposition half. He sidestepped an onrushing defender, then launched a looping 30-yard shot that dipped inside the right-hand post. The U.S., improbably, led 1-0.
