How many more years under achieving and basically getting by on her looks?
She won't get a better opportunity to actually win a tournament than the Japan Open. What happens? She is slaughtered by a qualifier who is the outsider of those left.
Showboating on match point down is not clever, it just makes you look a complete fool.
If she really wants to make a go of it (which on this sort of evidence seems very unlikely) she needs help to get her head sorted out. Eventually the looks will go and she will find that she has just wasted a career.
