Vera Zvonareva wins at Pattaya

PATTAYA, Thailand -- Two-time defending champion Vera Zvonareva defeated Tamira Paszek of Austria 6-4, 6-2 Tuesday in the first round of the Pattaya Open.

Zvonareva, who lost in the Australian Open semifinals to eventual champion Kim Clijsters, came from 3-1 down in the first set. She'll play Thai qualifier Nungnadda Wannasuk in the second round.

Ana Ivanovic won the first eight games to cruise past Thai wild card Nudnida Luangnam 6-0, 6-2. She will face American veteran Jill Craybas.

Daniela Hantuchova, who arrived in Pattaya on Monday after a Fed Cup loss in Slovakia, showed no sign of jet lag in her 6-2, 6-1 win over Kurumi Nara of Japan.

"It wasn't easy. I just came from the winter in Europe, so I didn't know what to expect," Hantuchova said.

She'll know what to expect in the second round: Japanese veteran Kimiko Date Krumm, who eased past Czech player Renata Voracova 6-2, 6-2.

Hantuchova has lost all three meetings after Date Krumm came out of retirement in 2009.
