Reasonable draw. Stosur hasn't been too impressive lately and at this very moment is getting her ass kicked by Petrova, Lena has some chances here. She already has beaten Stosur before, last year in New Haven: 3-6, 6-3, 6-4.
After that it could be either Bojanovski or Rodionova, both beaten in Istanbul, then probably Kleybanova and Dementieva for a QF against Clijsters.
There's no reason why Lena can't go very far here.
