Well NaNa will pass her soon but Vika will have little to defend after that (although NaNa won't either
). Ma$ha will have a chance to gain points at the end of the year but still not through the French Open.
Nana will stay number 2 for some time, she didn't play a lot of tournaments until French open and even then she didn't have much points to defend.
So close to the rest of the tour, actually a chance aga will surpass her if she doesn't perform well.....
