Argentina secured a spot in the 2006 World Cup by beating defending champion Brazil, 3-1, last night. The Argentines joined Iran, Japan, Saudi Arabia and South Korea as the first nations to qualify for next year's World Cup, along with host Germany, an automatic qualifier in the 32-nation field.

Two goals from striker Hernan Crespo led Argentina in Buenos Aires. Crespo scored in the third and 39th minutes and Juan Roman Riquelme added another in the 18th in a showdown between the two soccer powerhouses, winners of seven World Cup championships.

Roberto Carlos scored Brazil's goal in the 71st.

Argentina, World Cup winner in 1978 and 1986, leads the 10-team qualifying group with 31 points, followed by defending champion Brazil with 27. Ecuador is third with 23, followed by Paraguay with 22 after 15 games.

Mexico beat Trinidad and Tobago, 2-0, and Costa Rica edged Guatemala, 3-2, in the CONCACAF region.

At Monterrey, Mexico, the hosts didn't break through until the 65th minute, when Jared Borgetti put in a rebound against Trinidad and Tobago. Luis Perez added a goal from the right side in the 88th minute.
