It looks like just by virtue of her 4th Round showing (so far) at RG. Ana is so far #12 in the rankings, I would also like to point out that can change in case Marion can go deep in the tournament and/or if Sam can repeat (or better) her performance of last year.
Regarding on who is ahead of her.. I won't take Vinci into consideration cause she's playing Serena in 4R
Meaning that it should be between Ana and Maria Kirilenko to see who gets #10 after the RG fortnight or if Sam retains her spot. Marion's odds aren't looking so well (playing Schiavone, then more likely Azarenka)
Both Kiri and Sam still have to play their 3R, but if they lose let's say they lose in 4R and Ana progresses to the QF then the chances of being #10 are bigger. A SF as everyone knows will more than sure give Ana a return to the Top 10 after exactly 4 years of dropping out of it (Unless Kiri and Sam somehow decide to peak this week and make SF/F) Of course, the help of certain specific results wouldn't hurt but they can also go against Ana as well
and not to mention that anything is possible in WTA. The odds "seem" to be favor of Ana as of right now considering the current results, at least to be Top 12 after RG.
With that being said, Ana is Ana and we all know that. However, being in the Top 12 in time for Wimbledon will be good as well as she avoids the Top 4 in the Round of 16.
These are just possibilities, not concrete facts yet. It depends on Ana and we have to see what happens
Even if another loss to Agatha will make me go insane again
I posted something very similar in the "Eastbourne + Wimbledon" thread regarding her seeding for those tournaments but since this ls the ranking thread it's probably more appropriate to mention it in here.
