DALLAS, TX, USA - The inaugural Texas Tennis Open kicked off with a busy Sunday schedule that saw one of the seeds bite the dust in the first round. Australia's Jarmila Gajdosova was beaten by Sorana Cirstea of Romania in three sets, 36 64 62.

Both players faced 13 break points over the course of the 89 minute match, with 93rd-ranked Cirstea converting on seven occasions - just once more than world No.31 Gajdosova, but enough to make a critical difference.

Gajdosova wasn't the only favorite to struggle, although No.3 seed Julia Goerges found a way to overcome a dire start against Alizé Cornet. The rising German powered to victory over the Frenchwoman, 06 64 60.

"In the first set it wasn't happening for me out there… I hardly got a ball in the court and she was playing some really good shots," Goerges said. "In the second set I focused on my game, put a little bit more spin on the ball and tried to move her around. I'm happy that I have a chance to play a second match ahead of the US Open."

Other first round winners at the $220,000 International event included No.8 seed Irina-Camelia Begu, who beat Pauline Parmentier in straight sets, and Alberta Brianti, who beat US wildcard Irina Falconi, 63 62.

Gisela Dulko, Johanna Larsson and Anastasija Sevastova also moved through to the second round.

"Today the key for me was to start really well," said Dulko, a 60 63 winner over Bojana Jovanovski. "I felt really good on the court - it was just one of those matches when you go out there and feel really confident."

The top four seeds in the qualifying competition - Kateryna Bondarenko, Chanelle Scheepers, Angelique Kerber and Aravane Rezai - all secured berths in the main draw. Rezai edged Alona Bondarenko, 64 57 64.

Monday's schedule sees Sabine Lisicki face Sania Mirza, while top seed Peng Shuai tackles Melanie Oudin and second-seeded Dominika Cibulkova opens against Mirjana Lucic.
