¡¡ATHENS, Aug. 26 (Xinhuanet) -- A dedicated U.S. team produced a series of surprises in the Athens Olympic Games despite some disappointments from the track and field and tennis.

    Without a single sample of doping, the U.S. are contended with the performances of the delegation, said Robert Condron, director of media service of the U.S. Olympic Committee.

    "Lots of good things happens to our teams," Condron told Xinhuaon Thursday. "In gymnastics, we won the gold medals in men's and women's all-around events. That's our best shows ever in Olympics."

    Paul Hamm and Carly Patterson won the men's and women's all-around events respectively for the first time for the U.S.

    In fencing, Mariel Zagunis won the first gold medal for U.S. women's fencing with a victory in the individual sabre. Sada Jacobson took the bronze.

    "We've never won a medal in women's fencing, let alone a gold medal. We have many team events still left. We are very pleased the way we done here," Condron said.

    Condron said the happiest moment for him in the Athens Games came from eight medals from swimming sensation Michael Phelps and the three-peat Olympic title of the women's softball.

    "But the losses of Venus (Williams) and Andy (Roddick) disappointed me. They've tried hard," Condron said.

    Neither players advanced into the quarter-finals of the tennis tournament here.

    Marion Jones finished seventh in the women's long jump after the preliminary round, while Allen Johnson toppled in the men's 110m hurdles.

    "Other countries have done well, like Ukraine. It's good for the track to have the world involved."

    "We probably don't have the strong team we usually have, but weare very dedicated to helping clean up doping in sports. Sometimes you suffer because of that. But our goal is to have every American competing without performance-enhancing (drug)." Enditem
