The fourth and last Grand Slam tournament of the year will be thrilling to watch. Roger Federer will try to avenge his defeat in the final last year against Del Potro who accomplished the impressive feat of beating Federer and Rafael Nadal in the same tournament. Del Potro however, won't be here to defend his title as he recovers from a wrist injury. Rafael Nadal coming off his victory at the French Open after a season of struggles in 2009 will once again try to get the only Grand Slam he has not yet captured. Their main opponents will most likely be Andy Murray (finalist in 2008), Novak Djokovic (finalist in 2007) and Andy Roddick.
