BERLIN (AP) _ Steffi Graf led the way into the quarterfinals of the German Open today, while 15-year-old Martina Hingis was beaten.

Graf rolled past Yayuk Basuki of Indonesia 6-2, 6-1.

Karina Habsudova of Slovakia, No. 54 in the rankings, ousted Hingis 6-3, 7-5. The loss came just one week after Hingis beat Graf to reach the finals of the Rome Open.

Graf admitted she's still not feeling comfortable enough on clay to take risks after the loss to Hingis capped a rocky tournament last week in Rome.

``I played a little safer today, but better,'' said Graf, the top seed. ``Naturally, it's not spectacular, but people forget that's how most of the points are won.''

Arantxa Sanchez Vicario, No. 2 seed, advanced into the third round with a 6-3, 6-3 victory over American Marianne Werdel-Witmeyer.

But No. 6 Amanda Coetzer of South Africa became the day's second upset victim when Jana Kandarr, a 19-year-old German, beat her 7-6 (7-4), 2-6, 6-3.

France's Mary Pierce also reached the third round, along with Austrians Barbara Paulus and Judith Wiesner.

Anke Huber of Germany came within two points of losing before she rallied past American Lindsay Lee 3-6, 7-5, 6-3.

Lee, who already had victories over two top-10 opponents in less her two years on the tour, led Huber 6-3, 5-3, 30-30, before the German dodged the upset.
