BBC Sport in Flushing Meadows
After quitting as defeat in an match due to harm against Korean 23rd seed Stan Wawrinka, defending champion Novak Djokovic is.
Djokovic retired with a shoulder issue seconds after he was left by a double error two places and a break down.
The Serb’s conclusion was approached by loud boos, with more as he walked off court, heard.
“I’m accountable for the crowd. They arrived to see a full match but it wasn’t to be,” said world number one Djokovic.
Three-time Grand Slam champion Wawrinka had mastered the last-16 competition in a boisterous atmosphere at Arthur Ashe Stadium, producing a powerful screen reminiscent of his best to direct, when Djokovic determined he could not continue.
34, wawrinka, will play fifth seed Daniil Medvedev from the quarter-finals.
Djokovic was the hot favourite to retain his title in Flushing Meadows and acquire a 17th Grand Slam, which will move him closer to Roger Federer (20) and Rafael Nadal (18) in the race to become deemed the best men’s player of all time.
However he had been hampered throughout the championship with a left shoulder injury, which he states has left him “continuous pain for a few weeks”.
Djokovic particularly struggled during his match against Argentina’s Juan Ignacio Londero on Wednesday, requiring treatment that was intense three times until coming through in straight sets.
There was speculation he might withdraw due to the issue, only to show signs of the issue at a win on Friday.
But Djokovic reported the pain returned against Wawrinka’s intensity.
“it’s very frustrating. Of course it hurts that I had to retire,” said the Serb.
“A few days the pain has been greater, some times with less intensity. Clearly I was taking things to kill the pain. Sometimes it works, sometimes it doesn’t.
“You only know when you realize, when you feel like you’re not able to reach the shot any longer.”
The Serb did not want to explore the crowd’s response to his departure, while Wawrinka stated negativity amazed him.
“He is an incredible champion,” added the Swiss. “If he’s got to retire, then it’s not the very best for a tennis player to have to leave the courtroom like this.”
Djokovic suggested he hopes to regain fitness to the Asia leg of the ATP Tour and the season’s months.
“It’s no secret that I have need and a goal to reach the most Grand Slams, and reach Roger’s album,” he added.
“At exactly the exact identical time, it is a very long road ahead ideally for me. I am hoping I can play for many years. I am planning to. I really don’t see a finish supporting the corner whatsoever.”
The withdrawal of djokovic failed to take the glow from Wawrinka, who earned his victory since beating on then world number one, Britain’s Andy Murray, at the 2017 Open semi-finals.
Shortly after this run, the career of Wawrinka stalled.
It’s been a gradual climb back up the rankings three, however he can still cause difficulties for the – all of their bodily state – in a display that is powerful.
Wawrinka came out firing from the beginning, piercing Djokovic’s famous defence using blistering groundstrokes as he broke 3-2 and producing thumping aces to fend off a break point in another game in his way to clinching the opener.
Wawrinka had conquered Djokovic 3 times at a Grand Slam – for example their last meeting in the 2016 closing at Flushing Meadows – having lost the opening set them in each.
This proved distinct, despite Djokovic coming from fighting by holding to love in the first game of the second set, and then breaking to gain an early advantage.
Wawrinka, backed with a vociferous New York audience, was soon level after breaking back in a pivotal seventh match where Djokovic coughed up two double defects operating for a 5-2 lead, and the Swiss landed a gorgeous one-handed backhand down the line which left some fans climbing to their feet in honor.
Djokovic started to look rattled by the atmosphere and the accident, finding poor shots as he attempted to respond, allowing Wawrinka another break and the chance to work out to get a two-set advantage.
Treatment in the changeover was a last-ditch attempt by Djokovic to improve his physical – and possibly mental – condition, but it didn’t prove effective and he stopped a couple of minutes later.
“I am sorry he had to retire to complete the match like that, but like me, most significant is the way I’m playing, how I’m shifting,” Wawrinka stated.
“The longer the game was going, the better I was playing. I had been hitting the ball really hard. I was feeling great on court”

Wawrinka had been in form. He pummeled the chunk and depriving us.
Djokovic was, however, very subdued. He appeared to be observing events, as opposed to influencing them.
To leave the court with boos ringing in his ears turned into a for a 16-time Grand Slam winner, although only he knows whether he might have finished the match.
The chances on Nadal and Federer will now shorten further. But we need to look outside the top three.
Wawrinka could be 34, but he can be exceedingly tricky to stop, if he reaches the next week of a Grand Slam in this sort of mood.
