One day, Aga will manage to win again some sets and surely some matches against Vika, that's not in doubt
Before Doha 2012 their matches were always tight, then Vika got the edge.
But Aga has worked on her H2H with some players quite well recently, such as Ivanovic (from 0-3 to 5-3), Schiavone (from 0-4 to 3-4), Zvonareva (from 0-2 to 4-2), Wozniacki (from 1-5 to 4-5)... I could add Venus Williams but it's a little bit special and not very significant, given the American's health problem and the amount of matches they played recently (1-6 to 3-6 after two easy wins in straight sets).
Nevertheless, again, H2H are only statistics and are not that important anyway.
