Wednesday's WTA Tour round-up

Dokic was made to work hard for her victory

Jelena Dokic fended off Miriam Casanova of Switzerland to go through to the quarter-final.

Fourth seed Dokic had to fight off set points from Casanova in both sets before prevailing 7-5 7-6.

In the 26-point tiebreaker, Casanova held four set points before Dokic finally claimed victory on her fourth match point.

"She returns well and puts pressure on you to get the serve in, but I served well and won the big points, especially in the tiebreaker," Dokic said.

"It was just a matter of if she was going to miss or hit a winner. There was nothing in between with her.

"Sometimes she would hit four winners in a row I could do nothing about."

Russian 10th seed Tatiana Panova bowed out 6-2 6-1 to Czech newcomer Sandra Kleinova in their first-round match.

World number three Venus Williams received a first-round bye and will play qualifier Zuzana Ondraskova of the Czech Republic in the second round on Thursday.

Croatia's Silvija Talaja beat second-seeded Silvia Farina Elia of Italy 1-6 6-3 6-2 in the second round.

The 96th-ranked Talaja, a finalist here in 1996, needed almost two hours to defeat the 24th-ranked Italian and advance to her second WTA quarter-finals this year.

In other second-round action, Tathiana Garbin of Italy defeated Emmanuelle Gagliardi of Switzerland 5-7 6-4 7-5 and Ludmila Cervanova of Slovakia beat Angelika Roesch of Germany 6-7 6-3 6-1.
