If anyone thinks that bringing up things like pipes, logoed golf balls, Alzheimer's, single dot marks, etc. is over the top or a waste of time, just look at what's happening with the LPGA and their 88 Rule.
This simple and easily enforceable rule was apparently intended to discourage awarding sponsor exemptions to inferior players, which seemed reasonable until 2 unusual cases came along this week:
1. MacKinzie Kline, the 15-year-old from California given a sponsor exemption by tournament host Annika Sorenstam, who was allowed to use a cart and oxygen because of a congenital heart defect. She shot 89 and has been banned from LPGA events for the rest of the year. The rule has turned a great PR situation into terrible PR.
2. Michelle Wie, who already has 7 top-10's in LPGA majors, who is only a non-member because of her age, and who is coming off of a double-wrist injury which clearly hasn't healed yet. She was flirting with 88 before having to WD to avoid being banned for the year.
Just goes to show that you have to consider all these unusual scenarios before you (re-)write a rule, and why rule (re-)writing isn't such a simple process.
