Dave,
He was an unkown at the time and had only qualified for the Open the week before by coming second in the Scottish Open. I was at that event and had followed him round and was mightily impressed. I only wish I'd done it again at Carnoustie last year. He was still 10/1 for a top ten.
You can still get 10 or 20 to 1 on better known players getting a top ten finish, though. Will be interesting to see the odds when they come out. Will probably have 3 or 4 £25 bets myself just to keep it interesting.
