NEW YORK -- Lindsay Davenport spent the better part of Monday sitting by a window at the National Tennis Center while rain fell. Once play started, she rose to the occasion.

	Lindsay Davenport won 12 of the last 14 games to move into the quarterfinals.

Playing just her fifth tournament since knee surgery, Davenport moved into the U.S. Open quarterfinals by beating 13th-seeded Silvia Farina Elia of Italy 6-3, 6-1 in a match that started more than 7 hours late because of downpours.

"It was hard for me to get going. I really didn't have a lot of time to'' prepare, Davenport said. "I'm so relieved it's over with, but I don't remember going out there too many times with no warmup, not a lot of notice.''

Jennifer Capriati, who defeated Amy Frazier 6-1, 6-3, also moved into the quarterfinals, where Capriati will meet 10th-seeded Amelie Mauresmo, who knocked off No. 7 Kim Clijsters 4-6, 6-3 7-5. Mauresmo beat Capriati in straight sets at Wimbledon and in a hard-court Open tuneup.

No. 11 Daniela Hantuchova got past No. 8 Justine Henin 6-1, 3-6, 7-6 (4) in a match stopped Sunday in the second set right after Hantuchova hurt her ankle and right thumb in a tumble on a rain-slicked court. Hantuchova meets top-seeded Serena Williams for a semifinal spot.

Rain that fell through the night continued into Monday, and organizers postponed 60 doubles and junior tournament matches. They were still hoping to be able to fit in a big schedule of main draw singles action, though by 8:45 p.m., only Davenport and Capriati had completed their matches.

"The bad news is: We're behind in matches, doing the best to make them up,'' tournament referee Brian Earley said. "We're certainly hopeful to get where we need to be. We know it's a hardship.''

Davenport only had a hard time right at the start against Farina Elia, dropping the first two games. Then she turned it on, winning four straight games and 12 of the remaining 14. Davenport won eight of the last nine points in each set, closing the match by breaking Farina-Elia's serve at love.

"Once I got back on serve pretty early, I think I felt a lot better out there,'' Davenport said.

The American finished 2001 atop the rankings, but she was out from November until last month because of her knee injury. While Davenport and another former No. 1 player recovering from surgery, Martina Hingis, were sidelined, Serena and Venus Williams met in the last two Grand Slam finals and climbed to 1-2 in the world.

In Davenport's comeback, she reached the semifinals in the first two and the finals in the last two. Two losses came against Venus Williams, including the title match Saturday in New Haven, Conn.

She spent nine weeks on crutches after her operation in January, then endured months of rehabilitation that included eight hours a day using a machine that repeatedly bent and straightened her right knee.

Davenport also changed her diet and has appeared fit in her four victories here.
