on their homepage they use rankings as of Jan. 21, 2013 for the current Entry Lists, so it´s obvious that Sabine is ranked higher there, even Barthel is behind her on that List but that won´t be the case when they do the draw, Sabine will be unseeded if there aren´t more withdrawals (she needs two I think)
Petkovic:I didn't know Sabine Lisicki because she was based in Bradenton, and I didn't see her in juniors. But in the past three years as we started playing Fed Cup together we got close. I love her. She was the first one to help me when I was going through some tough personal problems in Luxembourg. I actually can't believe that all the Fed Cup girls are getting along so great. Too good to be true!
