quote from Patty's website:
"I already went out on the court more than 40 times in the Fedcup for Switzerland, which is more than anybody else has done."
Patty had a fight with Gagliardi (or Casanova, can't remember) two years ago, since then she has said a zillion times that she won't play Fedcup any more. But if Hingis announces she's going to play, that would put a lot of pressure on Patty to come back. So it really depends on what Hingis decides.
