Sampras solves Korean puzzle

The hard-hitting Dutchman hammered home 15 aces against Hrbaty and will next train his dangerous serve-and-volley game at Sampras, whom he has beaten six times in nine previous career meetings.

In the women8217;s section, world number one Martina Hingis advanced to the quarter-finals defeating French 11th seed Sandrine Testud 6-2 6-1 in a match halted on Sunday due to rain.

The Swiss 19-year-old was leading 6-2 1-0 when play was suspended before finishing off the match in 58 minutes. Hingis will face sixth seed Monica Seles for a spot in the semi-finals against either third seed Venus Williams, the 20-year-old American who won Wimbledon, or French eighth seed Nathalie Tauziat.

Defending champion Serena Williams also advanced to the last eight stage defeating 17-year-old Wimbledon semi-finalist Jelena Dokic 7-6 9-7 6-0.

Williams made 24 unforced errors in the first set and benefited from a controversial line call in the tie-break to save a match point.

But there was a heartbreak for French Open champion Mary Pierce, as the fourth seed retired from her fourth-round match with Anke Huber after losing the first set 6-4 and suffering with nagging shoulder pain.

Pierce double faulted six times in 38 minutes of play but said the pain got worse with every serve.

Huber, the 10th seed from Germany, advanced to face an unseeded foe, Russia8217;s 18-year-old Elena Dementieva, who ousted American Lilia Osterloh 6-3 6-7 4-7 7-6 7-5, in a quarter-final match.

Tuesday8217;s action saw one upset of substance as Spain8217;s Carlos Moya ousted eighth-seeded compatriot Alex Corretja 7-6 7-4, 6-3, 4-6, 6-4 in a third-round match held over from Sunday8217;s drenching rain.

Moya, who beat Corretja in the 1998 French Open final, had slipped to 55th in the rankings after struggling to find his form because of back problems.

The 24-year-old Moya will next meet 1999 Open runner-up Todd Martin, who completed a straight-sets victory over 10th seed Cedric Pioline of France.

Advancing to a quarter-finals clash were ninth seed Lleyton Hewitt of Australia and unseeded Arnaud Clement of France8211; both of whom will be playing in the round-of-eight for the first time in a Grand Slam.

Hewitt crushed seventh-seeded Swede Thomas Enqvist 6-3, 6-2, 6-4 while Clement, who ousted top-seeded 1999 winner Andre Agassi in the second round, overcame Romanian Andrei Pavel 3-6, 6-2, 6-1, 7-6 7-5 in his fourth-round test.

Lee, who has been on an inspired run at the Open despite being ranked 182 in the World, showed no fear against Sampras and was full of fight in their opening set.

There were no service breaks in the opening set, though Sampras had to fend off triple break point in the sixth game.

Lee, who became the first South Korean man to win a Grand Slam match at this Open8211; losing two sets in posting three victories8211; appeared to have extended Sampras even farther in the first-set tiebreaker.

With Sampras leading 6-4 in the decider, Lee looked to have saved set point with a forehand volley winner, but his forward momentum carried him into net and both feet touched the bottom of net, giving the point to Sampras.

He sheepishly looked to the chair umpire, laughing, and point and set were awarded to Sampras.

The South Korean qualifier, who showed great speed on the court and an impressive forehand passing shot, fought fiercely in the second game of second set, which went to eight deuces.

Lee survived seven break points, but a double fault gave Sampras his eighth break chance of the game. Sampras cashed in at last as Lee8217;s backhand down the line went just wide, giving Sampras his first break of match for 2-0.

Sampras was off and running from there.
