But the strain was too much for Richard Krajicek's left knee. After a winning a lengthy struggle with Czech Slava Dosedel, 7-6 (7-3), 6-7 (7-4), 6-3, the Dutchman pulled out of his quarterfinal against compatriot Dennis van Scheppingen without hitting a ball.

EASTBOURNE: Jana Novotna worked for her spot while Arantxa Sanchez Vicario got a free pass to the finals Friday of the Eastbourne grass-court tournament in Eastbourne, England.

Novotna won her quarterfinal 6-4, 7-5 over fifth seed Irina Spirlea of Romania. She then beat Natasha Zvereva of Belarus in the semifinals 6-2, 6-1.

Sanchez Vicario beat Serena Williams in three sets in Friday's quarterfinals. She was to have played Anna Kournikova, but the Russian teenager withdrew to rest a right thumb injured in her quarterfinal victory over Steffi Graf on Thursday.

X-rays taken on the 17-year-old Kournikova were negative, but Kournikova - a 1997 Wimbledon semifinalist - withdrew, as a precaution, from a doubles quarterfinal Thursday and the singles Friday.

Saturday's final between the French Open champion and Novotna is a repeat of last year's Eastbourne championship, which was cut short by rain as the two shared the title.

"I'm going to do everything possible to be ready to play at Wimbledon. I'll be in treatment for 24 hours a day," Kournikova said.
