I think she should just let it go. Tracy said she was limping, and she will eventually have to retire in some match anyways. I just think she feels this pressure to show up not to dissapoint the organizers. However, I feel that she needs to just pull out before it gets worse.
Lindsay played so well today. If her foot is ok, she really has a chance - judging by her form last week against Dementieva and this week against Callens. Lindsay all the way!
