Despite knowing very little about men's tennis, I bet on Murray at 6.4 to win the championship before the start. I thought that I'd hedge if he got to the semi-finals and the big three were still in.
After winning 5 matches and not dropping a set since the first set of the championship he is now 6.6 on Betfair!
However, Djokovic can be got at 1/2 to beat him in the semi-final.
What price is Murray likely to be in the final against Federer (presumably) if he beats Djokovic?
6/4 ish
Think he'll be a lot shorter imo. If he knocks out the world number one he'll be 6/5, perhaps even shorter.

Murray's been bigger than 11/8 on one occasion and I don't see it happening after beating the world number one!
