Zina Garrison used the resilience of a Grand Slam veteran to hold off a strong challenge from a young Japanese player and advance to the third round of the Australian Open.

Garrison, runner-up at Wimbledon last summer and an Australian Open quarterfinalist or better five times, won the last five games of the match at the loss of just seven points and beat Nana Miyagi 2-6, 6-0, 6-2.Miyagi won the last six games of the first set, but did not hold serve from there on against the women's eighth seed. The world's 112th-ranked player was plagued by errors on her two-handed groundstrokes and fell quickly after her impressive start on center court as Garrison slowly got her game in gear.

"I'm still learning to play on this surface," Garrison said. "You can't attack all the time. You have to pick your moment, have patience and good groundstrokes."

The match was one of few highlights on the tournament's third day, when doubles filled the outside courts and the showcourts for the most part were turned over to unseeded Australians.

It also was a day on which Steffi Graf pushed the bad memories of 1990 farther into the past. Her tennis was improving, too.

On an outside court buffeted by winds as her life and reign as No. 1 in women's tennis were socked by family problems and rising stars in the last 12 months, Graf destroyed Maya Kidowaki of Japan to reach the third round of the Australian Open Wednesday.

The troubles of the past seemed far away. Graf needed just 41 minutes to complete the match 6-1, 6-0, lost only 10 points in the second set and got some more practice with the topspin backhand she's added to her repertoire. She now has lost a total of four games in her first two matches.

Boris Becker, the men's second seed, won 10 games in a row in the second and third sets to beat Marian Vajda of Czechoslovakia 6-4, 6-1, 6-3.

Gabriela Sabatini, the U.S. Open champion and fourth-seeded here, took just 52 minutes to beat Maria Ekstrand of Sweden 6-1, 6-1. Ekstrand won just 25 points the entire match.

Eighth-seeded Jonas Svensson of Sweden, 10th-seeded Guy Forget of France and 12th-seeded Jay Berger of the United States advanced to the third round in the men's draw. Women's winners included 10th-seeded Jana Novotna of Czechoslovakia and 13th-seeded Amy Frazier of the United States.

Sixth-seeded Arantxa Sanchez Vicario came back from a set and 1-4 down to beat Monique Javer of Britain 4-6, 6-4, 6-2.
