Roger Federer and Rafael Nadal are the two biggest names in men's tennis, and both will be looking to bring home the US Open title this year.
However, neither of these two players are ranked No. 1 in the world this time around as Novak Djokovic claimed that spot with his victory at the Wimbledon Championships.
Federer has struggled as of late and will be looking to pick things up in New York City.
He has been eliminated by Jo-Wilfried Tsonga in two of the last three tournaments he has participated in and has not advanced past the quarterfinals in any tournament since the French Open.
Nadal has also struggled as of late. He has not advanced past the quarterfinals in any event since Wimbledon and just recently lost to Mardy Fish in the quarterfinals of the ATP Masters Series Western & Southern Financial Group Masters.
Prior to that loss, Nadal took part in the ATP Rogers Cup, where he lost his first match to Ivan Dodig in three sets.
Both of these players will have difficult tasks on their hands to pick up their play at the US Open.
The competition certainly won't get any easier for these players, and if they continue to play this poorly, they will be in a lot of trouble in New York City.
