Wimbledon has become a bit predictable over the past few years as a result of the complete domination of Roger Federer, but are we about to see a changing of the guard? Federer is normally long odds on to grab the men's title, and when you consider that he hasn't been beaten on grass since 2002, it is easy to see why punters are prepared to take those odds. But, this year there hasn't exactly been a rush to back Federer, even though he is priced at 2.00 (longer than he has for 3 years), it seems that punters think that his reign may come to an end. There have been a few chinks in the Federer armoury starting to appear, he was beaten prior to Christmas when it was least expected, and of course he was on the receiving end of a nice old flogging in the French Open. Rafael Nadal has always had a question mark hanging over him on any surface other than clay, but the enormity of his French Open win, and victory in Halle last week has seen Nadal shorten into 3.20 to win Wimbledon. While we have found very few takers for Federer, there has been a lot of bets coming through for Nadal, who opened the week at 3.75. The only other player given any consideration at all is Novak Djokovic (5.00), although he is another who has had problems with consistency.

Maria Sharapova is 3.75 to win the women's title, and it would be fair to say that this year would be the most open ever, with question marks hovering above the head of most in the betting. Sharapova is at her best on grass, but was bundled out of the French Open after a couple of torrid battles against opponents in the early part of the draw, and the Williams' sisters suffered the same fate. Perhaps time has caught up to with the Williams' girls, and they have been hard to sell with Serena at 4.50 and Venus sitting on 5.50. We know only too well that you can never write them off, but it seems as though punters want to wait and see if they are at their best before backing them. We have seen some early action on Ana Ivanovic (including one bet of $1500) at 5.00 following on from her impressive win in the French Open, and with the tip being that the Wimbledon courts will be a lot slower this year, then Ivanovic has the game that may see her add the Wimbledon title to her list as well.
