Tom,
1 and 18. Do something to get yourself DQ'd on the 1st hole!!
Without going back and re-reading the rules, its very hard to get yourself totally DQ'd in match play. I recall there being a few ways for it to happen, but its very rare. John VB would know for sure, I suspect.
--On that same topic, I don't think you could lost 11-9 like Tom said. Since you all ready lost, you can't lose the same hole twice, and unless you have hit from the tee on 10, you will not lose 10 by having too many clubs either.
Worst beating--At least it felt like the worst, I lost 1 down to a guy I had to give up 16 shots to, I swear to this day if he posted scores using Equitable Stroke Control, he would have been no more than a 10 and I would have beat him at least 4 and 3. But whatever, I got hosed.
