NEW YORK, Aug. 27 (Xinhua) -- It wasn't a hard job for top seed Novak Djokovic of Serbia to get past the first round at U.S. Open, which was proved by a 6-1, 6-2, 6-2 victory over world number 112 Richardis Berankis.

It only took the current world number one 82 minutes to finish the match.

"I think the night sessions in New York are quite different from any other tournament because of just the vibe that you feel with the people, the crowd gets involved," said Djokovic.

"It's very exciting, always entertaining."

Djokovic outperformed his opponent both offensively and defensively, and the winner of six Grand Slam was looking forward to taking back his U.S. Open trophy which he lost last year on the same court.

"This is the last Grand Slam of the year," said Djokovic. "I have high expectations for myself."

"Knowing that I've done so well in past years, had such a good record, gives me enough reason to have this confident and optimistic approach."
