Ana earned 12 points this week so she'll re-enter the rankings on the Monday after Indian Wells. She'll be back in the top 1000, at least around #970.
She'll have more opportunities to pick up points next week and the week after, so she'll most likely re-enter the rankings higher than that. Just 4 more points (one $10K QF) would get her into the top 900. Ten more points would get her into the top 800.
I didn't know players are in the rankings just after 1 tournament now so I thought she will have to play 2 more tournaments to have rank but now I see players with only one tournament in the rankings. Well, I think Ana is top 200 material in the moment. Maybe that sounds too ambitious but she has career high at 273th position and from experience of some girls like Pandzic and Mijacika I think she can do it. They never were in top 300 before they stopped play but when they back to tournaments they qualified for top 200.
