Rafael Nadal is the world number 1 and he's also number 1 in the futures market for every Grand Slam for the next year.
Rafael Nadal is the current holder of both the French Open title and the Wimbledon title and he is favored to repeat both of those wins next season. Here are Nadal's odds to win outright for the next 4 Grand Slams starting wih the 2010 US Open:
2010 US Open: +300 (3/1) Boylesports
2011 Australian Open: +250 (5/2) Boylesports
2011 French Open: -225 (4/9) SkyBet
2011 Wimbledon: +200 (2/1) SkyBet
As is usually the case with favorites you are either dealing with very minimal value or you are working with odds that have to be considered too short to bet. Roger Federer is a co-favorite for the US Open and the Aussie and if he continues to falter then his price should drift, which may lead to Nadal's odds shortening.
However none of the prices above are likely to shorten until at least the late rounds of August's Canadian Open and that means there is no rush to back Nadal at this point.
Nadal is an injury prone player so the events that are far off in the future are risky plays.
Nadal backers that want to secure the world number 1 at a price that is at least somewhat decent should be taking him to win the US Open now but a comparable price will probably be available for most of the next month.
If Nadal is on-form in Toronto and deep into the draw then that would be your cue to back him for Flushing Meadows before his price shortens.
