anyone know how far laura has to get in this tournament in order to make the top 50?
One more win and she would be 2 points behind the current no 50. Semi-final should do it. Semi-final is where she would potentially meet Stosur, so as far as I can work out she can get into top 50 without having to beat Stosur.
She will lose 30 more points if she finishes her season in Osaka but it should still be enough to finish top 50!
If she wins the tournament she'll get to about 41. But that may be a little optimistic..
