Yugoslavia's Jelena Dokic, playing her season-opener after skipping the Australian Open, got her year off to a winning start with a 7-6 (7/4), 6-4 victory over rising Indonesian star Angelique Widjaja at the Pan Pacific Open tennis tournament in Tokyo on Thursday.
The second-seeded Dokic, ranked eighth in the world, started slowly, going down 0-5 in the first set, before storming back to win the second round match in 80 minutes.
Third seed Lindsay Davenport of the United States joined Dokic in the quarter-finals with a 6-4, 6-4 victory over 1996 Pan Pacific champion Iva Majoli of Croatia.
Dokic will play American Lisa Raymond, a 2-6, 7-6 (9/7), 6-2 winner over Magdalena Maleeva of Bulgaria, while Davenport will take on Thai ace Tamarine Tanasugarn.
Tamarine survived a 141-minute battle against sixth seed Silvia Farina Elia of Italy, winning 6-7 (4/7), 7-5, 6-1.
In other action, Sydney Olympic silver medallist Elena Dementieva of Russia, the eighth seed, breezed past French qualifier Stephanie Cohen Aloro 6-2, 6-2 and Lina Krasnoroutskaya became the only qualifier to reach the last eight with a marathon 6-7 (10/12), 7-6 (9/7), 6-2 win over fellow-Russian Elena Bovina.
Krasnoroutskaya will play top seed Monica Seles of the United States in the quarter-finals.
