Top-seeded Ana Ivanovic was saved by the rain Tuesday when the last set of her first-round match with Japan's Ayumi Morita was suspended at the Pattaya Open.
Morita was leading 6-3, 5-7, 2-1 when rain stopped play. The match resumes Wednesday.
Ivanovic, the 2008 French Open champion, could not get her serve going in the first set when she double-faulted five times, but the Serb fought hard to clinch the second set.
Seventh-seeded Elena Vesnina from Russia was also stalled while leading Greek veteran Eleni Daniilidou 6-3, 1-0.
All of the other seeded players in action won in straight sets: No. 2 Maria Kirilenko of Russia, No. 4 Sorana Cirstea of Romania, No. 5 Sabine Lisicki of Germany and No. 8 Heather Watson of Britain.
