Ana Ivanovic vs. Samantha Stosur
These 2 players just played a few weeks ago in Moscow, so I don't expect a different result on a similar surface. Ana needs to study what she did wrong in Moscow, and try to correct them against Stosur. I do expect a closer match this time, but I don't see Ana springing a surprise here despite her being higher ranked.
Pick: Stosur in 3 sets
Elena Vesnina vs. Tsvetana Pironkova
Vesnina in 2 easy sets. Pironkova doesn't belong here and never did.
Simona Halep vs. Elina Svitolina
Simona has already qualified, so it depends whether she wants to put in the effort or not. Still, I expect a half assed Simona to be too much for Svitolina. Elina only made it here by winning one of the weakest tournaments on tour.
Pick: Halep in 2 sets
