Having opened at home with a 2-2 tie against Trinidad & Tobago, the Salvadorans can't afford to lose to the Americans and open with only one point in two games at home.
The only newcomer to the training squad is former USL-2 (Real Maryland) player Dennis Alas, who returned to El Salvador and plays for Luis Angel Firpo.
The Salvadoran squad includes recent New York Red Bulls signee Alfredo Pacheco. Also selected were former Los Angeles area prep star Ivan Miranda and former D.C. United player Eliseo Quintanilla.
Pacheco is the only player currently affiliated with a foreign club.
After the U.S. game, El Salvador travels to Costa Rica to face the Ticos on April 1.
