“He really surprised me today with his fast play,” said Djokovic, who lost a set for the second time in this tournament. “After the first set it was 6-3 6-3 6-2, but it was just a few points that made the difference. I want to congratulate him on his good game.
Djokovic, who beat Tallon groenpoor in the previous round, increased his level and pace against Nishikori after losing the first set and kept his mission alive. He is only four wins away from the record 21 Grand Slam titles and wins in all major tournaments in the same season. In the next round, he will face the Russian Aslan Karatsev or the American Jenson Brooksby.
Seven years ago, Nishikori reached the final of the US Open. The Japanese have also reached the bottom four in New York twice. Because he fell in the standings, he met Djokovic at the start of the tournament.
