There is no score between the USA and Costa Rica at halftime of their World Cup qualifying match in Portland, Ore. The U.S. controlled possession for the bulk of the half, but was only able to generate a few scoring chances. The best opportunity came at about the 20th minute, when Tab Ramos struck a fine long ball that Ernie Stewart ran onto. The Dutch-based Stewart moved into the box, but his attempt to play the ball was deflected by Costa Rican keeper Erick Lonnis. Costa Rica made one substitution during the first half, with Campos replacing Paniagua in the 28th minute.
