    BEIJING, Jan. 11 (Xinhuanet) -- Roger Federer was upset at an Australian Open tuneup tournament Wednesday, though the loss won't count in his ATP record.

    The World number one lost his opening match against Tommy Haas as the Kooyong Classic exhibition tournament got underway in Melbourne today.

    Haas, ranked No. 41, fended off three break points while serving for the match and closed a 3-6, 6-4, 6-4 win with an ace in the opening match.

    Federer said on the eve of the Kooyong event that he was 100 percent healthy and had no concerns that the ankle problem that curtailed his last season would flare up before the Australian Open, which starts Monday. 

    In other matches Andy Roddick takes on French teenager Gael Monfils; Croatian Ivan Ljubicic plays Guillermo Coria; and Argentina's David Nalbandian will play Nicolas Kiefer. Enditem
