In the women's event, Ana Ivanovic admitted she allowed the conditions to distract her as she suffered a scare before beating Romanian Ioana Raluca Olaru 6-1 5-7 6-0.

"I was really upset when she broke me back on 3-2 in the second set, and I just struggled to find my game little bit," Ivanovic said.

"I wasn't moving enough and when it's windy day we really have to focus on footwork and moving the feet, and going around the ball, and I didn't do that well."

Elsewhere, Serbia's world number four Jelena Jankovic and twice champion Lindsay Davenport cruised through their opening matches.

Shrugging off the gusting winds, Jankovic crushed American wildcard Ahsha Rolle 6-0 6-2, while Davenport advanced when Argentina's Gisela Dulko retired hurt with a thigh strain trailing 2-6.

Davenport will play Taiwan's Chan Yung-Jan, who shocked 11th seed Sybille Bammer 6-1 6-3.
