No. 1 Novak Djokovic, No. 2 Roger Federer and No. 3 Stan Wawrinka survived round four at Flushing Meadows, but will they be able to advance out of the quarterfinals.

Federer in particuar will face a rather unexpected challenge in the form of No. 20 Gael Monfils, seeing how the Frenchman hasn't dropped a set at the tournament yet. Federer took a moment to reflect on how far he has come from his back injury last season.

"Because of the issues I had last year, I had to be unbelievably careful what I did. We had to cut back on a few things I usually would do, but were scared to do. That was not what I wanted to do," he said about his fitness work. "Sometimes if that's what it is and it means don't run on the treadmill or don't do jumps or whatever it is, well, there's other ways you can train that. I'm happy that basically today I can do whatever and I don't have any more setbacks.”

No. 3 Stan Wawrinka will take on No. 10 Kei Nishikori at 3:00 p.m. and No. 1 Novak Djokovic will face No. 8 Andy Murray under the lights at 9:00 p.m.
