[CONCACAF UNDER-20 CHAMPIONSHIP] FC Dallas keeper Richard Sanchez earned his third shutout in three games as host Mexico beat Jamaica, 4-0, to clinch the final Concacaf berth in the 2013 Under-20 World Cup this summer in Turkey. El Salvador -- with five players with ties to U.S. teams on its roster -- was a 3-1 winner over Panama in Wednesday's other game to join Mexico, USA and Cuba as the four Concacaf qualifiers.

Goals by Armando Zamorano and Marco Bueno gave Mexico a 2-0 halftime lead, and it added to its lead with goals from Francisco Flores and Jesus Escoboza on free kicks.

Jamaica's best chance came when Romario Jones' free kick crashed off the crossbar.

El Salvador came back from a goal down to beat Panama on two goals by Jairo Henriquez and one goal by Jose Pena.

Kevin Barahona, who started in midfield, was one of four Salvadorans who have played for Texas Rush.

Miguel Avendano, Diego Coca and Giovanni Zavaleta also moved to Rush as part of an international exchange program between Rush and FESA, a multi-sport program to provide opportunities for Salvadoran youth.

Also on the El Salvador roster is Anthony Dheming, who played for the Chivas USA academy team before joining Long Beach City College in the fall.
