World number one Novak Djokovic moved five matches from completing the first men's singles calendar-year Grand Slam in 52 years by advancing to the third round of the US Open on Friday. The 34-year-old Serbian cruised past 121st-ranked Dutchman Tallon Griekspoor 6-2, 6-3, 6-2 at Arthur Ashe Stadium to book a third-round date with 2014 US Open runner-up Kei Nishikori of Japan. "I'm as motivated as ever to do well," Djokovic said. "I'm not the only player that wants to go deep in the tournament and put his hands on the trophy. I'm trying to be my best every day and let's see what happens." Djokovic, chasing the first men's singles calendar Slam since Rod Laver in 1969, said the mental challenge was tougher than the physical one at this stage. "Probably it's more mental and emotional, really," Djokovic said. "I don't mind being on the court a long time. I feel I have more chances in a best-of-five. "It's more about handling everything that's happening off the court, all the expectations."
