Teen Powers to Win Over Sanchez Vicario

NEW YORK -- Fifteen-year-old Martina Hingis upset third-seeded Arantxa Sanchez Vicario 6-1, 3-6, 6-4 on Monday to move into the quarterfinals of the U.S. Open.

Hingis, the No. 16 seed from Switzerland, closed out the victory when Sanchez Vicario, normally steady from the baseline, sailed a backhand long on the first match point.

It was only the second time the two had met and both players ran down every shot, but it was Hingis who was almost perfect, taking the first set in 19 minutes.

Sanchez Vicario won the second set but the final set saw three consecutive breaks of serve until one hour, 45 minutes after they began, Hingis had her first career victory over Sanchez Vicario and a spot in the U.S. Open quarterfinals.

A month after she surprised the tennis world by winning the gold medal at the Summer Olympic Games, Lindsay Davenport shocked herself and the U.S. Open crowd Sunday with a collapse in the fourth round.

Hoping for a breakthrough Grand Slam victory, Davenport hit shots all around the court except inside the lines, as a steadier, more aggressive Linda Wild beat her 6-2, 3-6, 6-0.

"She started off playing unbelievable. She was too good for me. I kind of lost my confidence in the beginning. It's definitely a huge disappointment," said the eighth-seeded Davenport.

Wild raced to a 5-0 lead in the first set, then came back from the second-set loss to trounce Davenport in the decider.

Monica Seles struggled a little to reach the quarterfinals with a 7-5, 6-0 victory over Sandrine Testud.

Seles next plays Amanda Coetzer, a 6-4, 6-1 winner over Lisa Raymond. Conchita Martinez, No. 4, moved easily into the quarterfinals with a 6-2, 6-1 victory over Asa Carlsson.

On the men's side Stefan Edberg made it through with a 6-4, 7-6, 6-1 victory over Paul Haarhuis. Pete Sampras and Mark Phillipousis blew past their opponents to set up Sampras vs. Philippoussis IV, a sequel with "Rocky" overtones.

Sampras, the defending champion and No. 1 seed, reeled off 18 aces in a 6-3, 6-4, 6-2 rout of Alexander Volkov on the stadium court.

Philippoussis looked no less impressive with 25 aces in a 6-3, 6-2, 6-4 romp over No. 16 seed Cedric Pioline.

Philippoussis' serve was so intimidating that Pioline flipped his racket around at set point, trailing 40-0 in the second set, to try to hit the ball with the handle as if it were a baseball bat. Pioline foul-tipped the ball and lost the set.

Meanwhile, Swede Stefan Edberg stayed calm as ever in his last hurrah, winning a 6-4, 7-6 (7-4), 6-1 victory over Paul Haarhuis.

In reaching the round of 16, Edberg surpassed his showings in his last three visits to the U.S. Open -- third-round losses the past two years and a second-round exit in 1993.

Edberg's fourth-round opponent will be Britain's Tim Henman, who upset 12th-seeded Todd Martin 6-2, 7-6 (7-4), 6-4 Sunday night.

Goran Ivanisevic also advanced to the fourth round with a 6-3, 6-2, 7-6 (13-11) victory over Hendrik Dreekman.
