This is what the top 32 rankings, the probable seeds for AO will look like tomorrow (except the winner of Sofia will have an extra 120 points).
Petrova rises to #12, good for her. Like I mentioned earlier, that can make a big difference in AO R16.
Caro is back in top 10.
It would be nice to have her as one of the top 8 seeds for AO. But while she has a small chance to pass Stosur in the rankings before the AO draw if she wins both Sofia and Brisbane, she'd still need a top 8 withdrawal. Most likely she'll be in the 9-12 group, facing a 5-8 player in R16. I'd definitely prefer Errani from that bunch. I still can't quite see Errani as a serious top 8 player, but I shouldn't say too many bad things about her since it'd be pretty much the same things bashers say about Caro! I'd like to see how Caro matches up against this new and improved Errani on HC.
But before that, Caro probably faces a 17-24 seed in 3R. If Venus enters AO as the 24 seed, Caro - Venus could be a very interesting match. Caro's still 0-4 against her from their matches when she was 16-17 yo. I hope she gets a new chance to play Venus before she retires.
Edit: The difference between being the the 8th or the 10th seed at AO really shows in the possible 3R opponents. Against all the current 25-32 players, I'd consider Caro a huge favorite on HC. In the 17-24 group there are players like Goerges, Safarova and Venus, matches closer to 50-50. I'd like to see Caro play Venus, but if the American is having one of her good days, Caro's a small favorite at best.
