Analyzing his win over Sam Querrey in Cincinnati, Novak Djokovic said: "I had the nervous start, because, I mean, I didn't play a match for four weeks, I think.
So it took me a little bit of time to really adjust, to also hit big serve that was coming sometimes more than 135 miles an hour. I made three double faults in the opening game. Didn't have the greatest of starts. So it was a tricky match, quality opponent, big challenge."
