Australian Open Tennis Championships : Graf Powers Her Way Into 3rd Round, 6-0, 6-1

Steffi Graf made a big impression on Australian Janine Thompson Thursday as the 18-year-old West German needed only 40 minutes to win their match in the $1.9-million Australian Open.

Graf, top-seeded and No. 1 in the world rankings, displayed relentless power in a 6-0, 6-1 victory over Thompson, who is ranked 105th in the world.

“Steffi hits the ball as hard as anyone I’ve ever played,” Thompson said after her brief appearance on center court.

Graf was joined in the third round by fourth-seeded Pam Shriver; defending champion and fifth-seeded Hana Mandlikova, a new Australian citizen; eighth-seeded Claudia Kohde-Kilsch of West Germany, ninth-seeded Lori McNeil of Houston and 13th-seeded Swede Catarina Lindqvist.

Shriver won the last nine games in defeating Ros Fairbank of South Africa; Mandlikova trounced Hellas Ter Tiet of the Netherlands, 6-1, 6-1, in 55 minutes, and Kohde-Kilsch beat Australian Jo-Anne Faull, 6-2, 6-4.

Lindqvist breezed past Ann Henricksson, 6-2, 6-2, while McNeil ousted Manon Bollegraf of the Netherlanda, 6-4, 6-0.

Defending champion Stefan Edberg and former titleholder Mats Wilander advanced into the third round of the men’s competition.

Edberg, aiming for his third successive title, trounced West German Alexander Mronz, 6-4, 6-3, 6-1, while No. 3-seeded Wilander, a two-time Australia Open winner, beat Australian Simon Youl, 6-4, 6-2, 6-4.

Sixth-seeded Swede Anders Jarryd and eighth-seeded Yugoslav Slobodan Zivojinovic also moved into the round of 32 in the first grand slam event of the year, but another Swede, 11th-seeded Peter Lundgren, tumbled out.

Australian John Frawley, coming back after being sidelined with a broken wrist, routed Lundgren, 6-1, 6-3, 6-3, in the only upset of the day.

Dan Goldie defeated Canadian Martin Laurendeau, 6-4, 6-3, 6-1.

Puerto Rican Joey Rive, whose rackets were stolen overnight, had to play with borrowed ones in the first set of his match with Briton Jeremy Bates.

Replacement rackets were later found for Rive, who won, 5-7, 6-1, 6-2, 6-4.
