Ana Ivanovic vs Tsvetana Pironkova
These two are the only wild card entries here but only one is deserving of her wild card. Pironkova's appeal in Bulgaria is debatable, so it makes no sense to me to award a wild card to her for doing nothing much this year. Granted, she had a good run to the fourth round in Winbledon, but other than that, she practically invisible. Look out for an easy win for Ana.
Pick: Ivanovic in 2 sets
Maria Kirilenko vs Alize Cornet
It's difficult to predict Maria's matches as she has a thing for competing injured. We don't know for sure if she's fully healthy yet. However, she did push Serena in Beijing, so I expect her to be almost back. Against Cornet, she should have an advantage as Alize prefers the slow clay, even though she has a losing record against the Frenchwoman. Kirilenko needs to be careful though, as Cornet can spring a surprise if she's not focused.
Pick: Kirilenko in 3 sets
Simona Halep vs Anastasia Pavlyuchenkova
A rematch of the recent Moscow semi finals, Halep takes on Anastasia again in their opening Sofia match. On a similar surface, I expect the same results as Moscow, where the Russian got blown away by the Romanian. This tournament is Simona's to lose, having a stellar second half of the season and recent wins over the players participating here.
Pick: Halep in 2 sets
