Djokovic had a bit of a slow start, saving 2 set points before recovering to defeat ranked Benjamin Becker of Germany 7-6 (2), 6-2, 6-2.
Defending champion Andy Murray dropped a set to Leonardo Mayer en route to a 7-5, 6-1, 3-6, 6-1 win.
The ball is bouncing extremely high out there at the beginning, and he’s a big hitter of the ball,” the Scot said of Mayer. He served big, too ‑ bigger than I thought.”
“I had to defend a lot,” Murray said in an on-court interview after the match. “I think he played some really, really good tennis. It made for an entertaining match.”
Djokovic after a first set test only needed another hour for his straight set win.
“It was very tough,” Djokovic said of the windy conditions in Arthur Ashe Stadium. “You know, it was a lot of unforced errors, very windy conditions. You couldn’t really read and kind of predict where the ball is going to go, so you have to be very alert. At the start I had difficulty with my footwork.
“But, you know, as I won a set after that, it was very much, much better.”
“It was a lot of wind, wind that is not consistent, “said the Serb. “It changes direction all the time.
“So as I said, you have to be alert. And if you don’t, you know, go through the ball, if you’re not in a right balance, of course it’s not always positive to arrive in right balance. But you need to have this adjustment, footwork, steps, in order to get on the ball.
“I didn’t have that in the first set. I was still trying to find my way from baseline, and the other side he was serving well. I had my chances though first set earlier to break, but, you know, didn’t capitalize. After I played a good tiebreak, you know, and then everything kind of settled. I started to serve better.”
“I was a bit frustrated at points in the match because, “ said Murray,”I was doing quite a lot of the running for a lot of it. I wasn’t getting much depth on my returns, so when he was serving, you know, I was having to do a lot of running.
“When I was serving, I served a low percentage today. I served pretty well in my first match, and then today struggled to control the first serve.
“So I was, you know, playing a lot of points on my second serve. When that happens, you have to do a lot of the running. You don’t feel like you’re dictating the match. It can be frustrating.”
For his efforts on Friday, Murray plays another “Mayer” in the third round – Florian Mayer.
“He’s very tough,” Murray said. He comes to net a bit. He has a good slice backhand, but he hits it with two hands, which isn’t how remember normally you’re taught to play that shot.”
“He has very good feel up at the net. Hits a lot of dropshots. He’s a pretty flat ball‑striker. He has sort of huge, looping strokes. It can be tough to time your split step and know when he’s going to make contact with the ball.”
Djokovic will take on Portugal’s Joao Sousa for a place in the fourth round.
