“I did enjoy it, but I also suffered a lot on the court,” Djokovic said.<\/p>\n
“It was a very close match. He was probably the better player for the first set and he didn’t give me time to breathe. <\/p>\n
“I think I dug myself out of trouble with good serving, which obviously makes me happy.”<\/p>\n
Djokovic will face big-serving German qualifier Yannick Hanfmann in the third round.<\/p>\n
Sixth seed Ben Shelton looked rusty as he lost 6-2 6-4 to David Goffin of Belgium.<\/p>\n
The 22-year-old American, who has been recovering from a shoulder injury picked up at the US Open, struggled to find his rhythm in the first set and lost his serve in the third and seventh games.<\/p>\n
Shelton battled back in the second but an unforced error in the ninth game handed Goffin the advantage and the world number 83 closed out the contest.<\/p>\n
Goffin’s reward is a third-round match against Canada’s Gabriel Diallo, who is seeded 31.<\/p>\n
