FILDERSTADT, Germany -- Top-seeded Jennifer Capriati lost to qualifier Alexandra Stevenson 7-6 (3), 4-6, 6-4 on Wednesday in a second-round match of the Porsche Grand Prix.

The 35th-ranked Stevenson, who played three matches to reach the main draw, gambled on winners throughout and hit her second serve full strength to pressure Capriati.

The 21-year-old Stevenson, who reached the semifinals at Wimbledon as a qualifier in 1999, charged to a 5-2 lead in the third set before Capriati broke serve and closed within 4-5.

Stevenson broke back in the next game, winning a baseline duel and clinching the win in 2 hours, 11 minutes when Capriati netted a backhand.

Capriati, who reached No. 1 at the event last year when Martina Hingis injured her right ankle in the semifinals, was knocked out of the event in her first match for the third time.

Capriati, ranked third, pulled out of last week's Kremlin Cup because of a fever and sore throat.

Second-seeded Lindsay Davenport is to face Israel's Anna Shashnova later Wednesday.
