Ivanovic fell to Maria Sharapova in last year's final here.

"Last year's final was very emotional for me. I had trouble sleeping a couple nights after that," the 21-year-old said.

"It was still a great experience. I think I can still improve and build on my game, and hopefully take a step further this year. But I don't want to be too focused on the end. I'll just enjoy every match."

Elsewhere, Dinara Safina, the No. 3 seed, made it to the third round after a 6-7(3), 6-3, 6-0 win over compatriot Ekaterina Makarova.

Safina committed 20 errors in the first set but regrouped in the second and third sets, making a total of 24 errors the rest of the way en route to the come-from-behind victory.

World number one Jelena Jankovic and Russian Vera Zvonareva followed them into the last 32, although they had far different experiences.

Zvonareva, the No. 7 seed, took just 46 minutes to rout Edina Gallovits of Romania 6-0, 6-0 while top seed Jankovic was tested by the crafty Belgian Kirsten Flipkens, but was able to prevail 6-4, 7- 5.
