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.
she wasn't limping constantly, she only staggers a little bit after serving since she comes out of her serve on her bad foot, it's only normal to limp a little bit, but when she's walking or playing, its not like shes limping to every single ball
