FRISCO, Tex — Rockville Centre’s Crystal Dunn scored for the U.S. women’s national soccer team Wednesday night in a 5-0 romp over Costa Rica in an opening CONCACAF Olympic qualifying game.

Alex Morgan scored 12 seconds in and added another goal in the 62nd minute. Morgan’s goal was the fastest in CONCACAF Olympic qualifying history, and the team said it is believed to be the fastest in U.S. history.

Dunn scored her fifth career goal in the 15th minute, standing at the goal line as she followed her own saved shot.

The match was the Americans’ first competitive game since winning the World Cup. They have won three straight Olympic titles and four of the five in women’s soccer.

Carli Lloyd scored in the first half, and substitute Christen Press scored in the 83rd minute.

Morgan’s first goal was a right-footed volley to the left of goalkeeper Dinnia Diaz from about 13 yards out while being tightly marked on her left side. Lloyd assisted with a jumping header after collecting a long cross lofted in by Lindsey Horan from beyond midfield seconds after the opening kickoff.

Morgan’s second-half goal, her 59th career score, was a header just inside the 6-yard box off a chipped cross from Lloyd.

Lloyd’s goal came on a penalty kick after Dunn was tripped just inside the 18-yard box. It was her 83rd career score and 20th in her last 15 matches. She nearly scored again in the 59th minute on a point-blank header right at Diaz.

U.S. goalkeeper Hope Solo was never seriously challenged. She made two saves during the first half on long free kicks.
