PATTAYA (Thailand) (Agencies) - Second-seeded Ana Ivanovic downed American veteran Jill Craybas 4-6, 6-1, 7-5 in a second-round match which was suspended for 40 minutes because of an electricity failure at the Pattaya Open on Wednesday. Third-seeded Maria Kirilenko of Russia squandered three match points in losing to Kazakh qualifier Galina Voskoboeva 1-6, 7-5, 6-4, and sixth-seeded Peng Shuai of China defeated Elena Baltacha of Britain 2-6, 6-1, 6-4 in 1 hour, 51 minutes, marking the third time in five years Peng made it into at least the quarterfinals in Pattaya. She will face the winner between top-seeded Vera Zvonareva and local player Nungnadda Wannasuk. Ivanovic, the 2008 French Open champion, was a break down at 2-1 in the first set in her first match with Craybas when the blackout occurred. In the second set, she was double break points down but reeled off five straight games to win it 6-1 and force a decider. Ivanovic blew a 3-2 break lead but refocused to break in the 11th game and go on to win in 2 hours, 12 minutes. It was tough, especially mentally, in the end, said Ivanovic. I was happy to pull off that victory. Winning match like that was good for me. She next plays fifth-seeded Italian Roberta Vinci, who beat Chinas Zhang Shuai 7-5, 6-1. Kirilenko led 6-1, 5-2 and served for the match at 5-4, 40-0 but let her nerves get the better of her. She built a 3-1 lead against Voskoboeva in the third set and failed again to capitalize on the opportunity. It was the second premature exit from Pattaya for the Russian, who as the second seed in 2007 was knocked out in the first round. I wasnt in the match at all until I was down 3-0 in the second set, Voskoboeva said. But I started to play better from then. When you are down match point at 4-5, 0-40, you need luck as well. But I didnt think about that. I just played point by point.
