NEW YORK -- Five former women's champions -- Martina Hingis, Lindsay Davenport, Monica Seles, Serena Williams and Arantxa Sanchez-Vicario -- moved into the second round on opening day of the U.S. Open on Monday.

Top-seeded Hingis used precise if not power tennis to eliminate wild card Laura Granville 6-2, 6-0 in 46 minutes. Davenport, seeded No. 3, ousted Andrea Glass 6-2, 6-3.

Hingis was in command against the two-time NCAA champion from Stanford. She won the last nine games and finished the match in 46 minutes.

"To open the stadium is always a great honor," said Hingis, who won the U.S. Open in 1997. "There's pressure all the time. I love the challenge. The motivation is always there."

After dropping the first three games, Granville broke the Swiss star to briefly get the first set back on serve.

But Hingis was not about to stumble against Granville, a 20-year-old from Chicago who set an NCAA record with 58 consecutive singles victories over 13 months.

Hingis did not drop another game. She took advantage of 29 unforced errors by Granville, who was making her center court debut at the Open.

Davenport, who won the Open in 1998, displayed the power shots Hingis lacks. She rode a serve that reached 107 mph to six aces and wore down Glass, who missed the 2000 season because of mononucleosis.

Playing under threatening skies, Davenport advanced comfortably in 44 minutes.

"I feel I served well," she said. "I've had a good summer, a consistent summer."

Seles, a two-time Open champion, made a fast start with a 6-1, 6-2 victory over Australian Nicole Pratt. Seles, the seventh seed, was in control throughout and never gave Pratt a chance to get into the 58-minute match.

Playing in the old Louis Armstrong Stadium where she won the U.S. Open as a teenager in 1991 and 1992, the 27-year-old Seles pounded 24 winners in a lopsided affair.

No. 10 Williams overcame a slow start and 42 unforced errors to beat Anca Barna 4-6, 6-1, 6-2. No. 20 Sanchez-Vicario had a much tougher time, edging Petra Mandula 6-3, 3-6, 7-6 (5).

The last Grand Slam title for Hingis came at the 1999 Australian Open. She also is in danger of losing her grip on the No. 1 world ranking, with Jennifer Capriati hovering close behind and poised to overtake her should Hingis stumble during the fortnight.

"There is pressure all the time," Hingis said. "But I like the challenge and the motivation is there."

Granville, in any event, was suitably impressed.

"She's still No. 1," Granville said.

"For some reason I wasn't comfortable out there. I couldn't get my rhythm. Martina played very well, but I just couldn't see the ball."

Next up for Hingis will be big-serving Russian Lina Krasnoroutskaya, who defeated American Jill Craybas 7-5, 6-3. Barbara Rittner of Germany beat American Amy Frazier 6-1, 6-2 for her first Open victory since 1996. No. 6 Justine Henin defeated Marissa Irvin 6-3, 6-3.

Venus Williams and Jennifer Capriati are the leading contenders for the women's crown. Hingis, Davenport and Williams could also pose a threat.
