I don't think it's a very good one...
Two dangerous matches (even though I agree about Sabine) and a nearly impossible third one. All in all, Ivanovic narrowing their H2H to 1-2 would be a fair showing for Shahar.
In these days, every win for Shahar is a blessing, and may help building her confidence.
I wouldn't any win for granted, the way Shahar is playing now.
The match against Bammer, if she will win 1st round, will not be easy.
