Roger Federer enters the 2014 U.S. Open as the No. 2 seed in the men's draw. His first-round opponent will be Marinko Matosevic.
Here is a look at Federer's past performances at the U.S. Open.
Federer won five consecutive U.S. Open titles from 2004-2008.
Federer's lowest finish in the U.S. Open has been in the fourth round, which happened to him four times, including three straight years, from 2004-2003.
He has finished as a semifinalist twice in the tournament.
In 2013, Federer lost in the round of 16 to 19th-seeded Tommy Rebredo.
Federer has participated in two double's events at the U.S. Open, finishing second in 2000 and third in 2002.
Since winning his last title in 2008 at the U.S. Open, he has seen a steady decline in his finishes. He was a runner-up in 2009, and then followed that up with two straight semifinal appearances, a quarterfinals and then the fourth round exit in 2013.
The U.S. Open was one of only two events that Federer didn't make an appearance in during his debut season in 1999.
