Sounds like a good bet. I'd say Tennis is less predictable then some sports, need to check his record. Also Wimbledon has been excluded from world rankings for barring Russian players, though I imagine the money remains a large enough incentive. Djokovic was deported from Australia, I think he is angry enough to win now :p
Djokovic has not been in the best shape this year but is the big favorite to win. According to the bookies, Nadal is the number 2 candidate to win, but he still has his foot injury and grass is not his favorite underground. Maybe we get a surprise with one of the younger talents, so it can be an interesting tournament to watch.
