Fresh off her quarterfinal victory over defending champion Serena Williams, Lindsay Davenport attempts to move into her second U.S. Open final in three years when she faces unseeded Russian teenager Elena Dementieva.

Hingis, the top seed and 1997 champion, earned a spot in the semifinals here for the fifth straight year with a 6-0, 7-5 victory over two-time champion Monica Seles on Wednesday night.

The world No. 1 has looked dominant as she seeks her first Grand Slam title since the 1999 Australian Open. She has not dropped a set in her first five matches and lost a total of 15 games.

Although it is not reflected in the rankings, Venus Williams has played like a No. 1 player since claiming her first major title at Wimbledon. After her triumph in London, she has gone on to capture her next three tournaments to extend her winning streak to 24 matches, a season-high on the WTA Tour.

Venus Williams, seeded third, lost her only set of the tournament in her quarterfinal victory over eighth seed Nathalie Tauziat of France, calling her performance "unacceptable."

Today her performance must be of high-caliber against Hingis, who has lost to Venus Williams in three of their last four meetings, including a three-set defeat in the Wimbledon quarterfinals.

Overall, Hingis holds a 9-6 lifetime record against Venus Williams, including a 2-0 record at the U.S. Open. Hingis defeated her in the 1997 final and prevailed in three sets in a dramatic semifinal last year.

Davenport, the 1998 champion, appears to have shaken off a foot injury that affected her during her U.S. Open tuneup events and has played her best tennis since the beginning of the season, when she put together a 21-match winning streak.

That was never more evident than during her straight-sets victory over Serena Williams in the quarters, when she outslugged the defending champion to stop a five-match losing streak against her.

Davenport is looking for her fourth career Grand Slam title. She won her first here in 1998 before claiming crowns at Wimbledon in 1999 and the Australian Open earlier this year. She lost to Venus Williams in the Wimbledon final.

The 18-year-old Dementieva has pulled out three-set wins in her last two matches, including a quarterfinal win over 10th seed Anke Huber of Germany, to advance to her first Grand Slam semifinal. She also stunned seventh seed Conchita Martinez of Spain in the third round.

This will be the fourth meeting between Davenport and Dementieva in 2000, with Davenport winning the previous three. In their most recent encounter, Davenport won in straight sets at the estyle.com Classic in Los Angeles. Davenport also crushed the Russian, 6-2, 6-1, in the semifinals at Indian Wells.
