You can do it with Serena out ... You beat Kim on HC, Venus is not in form, Lindsay and Jennifer also lost from you on HC recently ... Amelie could be a serious obstacle, but Amelie still need to find her form. Justine's the top shot for this title, but I'm glad the press doesn't see it. Their would lie too much pressure on her then.
I hope for an Justine-Venus final with a win for Justine ... And the no. 1 position if Kim loses before the QF (which is unlikely, but not impossible if she's still burned out).
