SAN SALVADOR - The United States scored twice in the last 15 minutes, including an 88th minute equaliser, to snatch a dramatic 2-2 draw away to underdogs El Salvador in a World Cup qualifier on Saturday. The Central Americans went ahead in the 15th minute with a goal from playmaker Eliseo Quintanilla, who collected a pass from Osael Romero and slipped the ball inside the far post. There were more wild celebrations at the Cuscutlan stadium when Rodolfo Zelaya broke down the right and crossed for Cristian Castillo to score with a downward header for the hosts in the 72nd minute. El Salvador's troubles began when goalkeeper Miguel Montes had to go off injured and was replaced by Juan Gomez almost immediately afterwards. Substitute Jozy Altidore began the fightback by heading in from Frankie Hejduk's cross in the 76th minute. With two minutes left, Gomez was blocked by one of his defenders as he tried to collect a corner and the ball fell for Hejduk who scored from close range. The U.S. nearly snatched a winner in the sixth minute of injury-time when Brian Ching's effort was cleared off the line. The U.S. lead the final stage of the CONCACAF qualifiers with four points from two games while El Salvador, who themselves fought back from 2-0 down to draw 2-2 with Trinidad-Tobago last month, have two.
