NEW YORK, Aug. 31 (Xinhua) -- Five-time grand slam winner Martina Hingis was beaten 6-2, 6-4 by unseeded Frenchwoman Virginie Razzano in the second round on Thursday.

    This was her quickest ever exit at the U.S. Open.

    In eight previous tilts at Flushing Meadows, the worst showing for the 25-year-old Swiss, who won the 1997 title, were two fourth-round results.

    The eighth-seeded Hingis, returning to competition this season after a three-year absence, struggled with her serve, losing six successive service games at one point, and was erratic with her usually reliable groundstrokes.

    Hingis said her showing was a combination of being worn out from her three-set victory over China's Peng Shuai on Wednesday and Razzano's high level of play.

    "I think after yesterday I didn't have much more to give," Hingis said after the 64-minute defeat. "I was a little flat and tired mentally. I just don't know. I just wasn't feeling well. It wasn't my day.

    "Well, I think it's not only that she played well, but I didn'tplay good. I think I let her play well, and then she just, opened up, lost the fear, and played exceptional."

    Razzano, ranked 112th in the world, matched her best showing ever in a grand slam. In 27 previous grand slams she had reached the third round three times. In five previous U.S. Opens she had never advanced past the second round.

    The 23-year-old Razzano will meet Kaia Kanepi of Estonia in thethird round. Enditem
