In 1965, the U.S. played four games, all qualification matches for the 1966 FIFA World Cup. Gerley started all four games as the U.S. went 1-1-2 and failed to qualify for the finals. Gerley kept one clean sheet when the U.S. defeated Honduras 1-0 on March 17, 1966. The U.S. national team had no games in 1967. By 1968, Gary DeLong had become the team’s starting goalkeeper and Gerley played only two games, one as a second-half substitute. His last game with the national team came in a 5-2 exhibition loss to Haiti on October 21, 1968.
