The Serbian made short work of Damir Dzumhur in his first round match, disptaching of the Bosnian in straight sets.

"He's one of the quickest players on the Tour. He played some really good shots and it was anybody's game midway through the second set," Djokovic said on court after the match. "I was pleased to close out the second set and then stepped it up a couple of levels."

The World No.1 struggled towards the end of the Western & Southern Open last week, where he captured the trophy and equaled Rafael Nadal's record of 35 ATP Masters 1000 titles.

“I did struggle a bit with the semi-finals and final back to back last week, but I had 48 hours," Djokovic revealed. "Not so much time, but still enough time to recover. I felt good on the court today. The good thing about a Slam is that you only play every two days, so you have at least one day of rest and recovery. I’m going to try to use that as much as I can and gather all my energy and strength for the next one.”

With the US Open lacking fans in attendance, Djokovic relied on his box for encouragement and support. The Serbian was spotted looking at his entourage on numerous occasions, although he did not require much motivation to win this match.

“Your team, your box, is always cheering you on. Regardless of whether you have an empty or full stadium, you always turn to them mostly. You look up to them, expect them to be with you and support you on the journey throughout the match,” Djokovic said. “Maybe you don’t want your box to clap when your opponent makes a mistake. Damir is a very good friend, so it’s a little bit awkward. But at the same time, it’s a Grand Slam, first round, biggest stadium in our sport [and] we want to start well."
