World No. 2 Novak Djokovic, who hasn't had a week off since the start of the Olympics, says he needs to rest. Djokovic reached the semifinals of the Olympics, won Toronto, and on Sunday lost in the final of Cincinnati to Roger Federer.
"Maybe playing couple weeks in a row, four weeks in a row, got me maybe mentally. Physically it didn't," he told reporters. "I felt OK on the court. We move on. There is New York in a week, and I really need to perform my best there. No doubt obviously we know there is disappointment…The conditions here are quite different from U.S. Open. It's a bit slower there, which I think goes in my favor a little bit more. More suitable to my style of the game. I'm going to have a week that I think is very necessary for me right now mentally and physically."
