Djokovic is out of Open
Novak Djokovic's US Open title defence came to an end after he retired injured while two sets down to Stan Wawrinka.
The crowd on Arthur Ashe were stunned when the world number one (above) approached Wawrinka and embraced him while trailing 6-4 7-5 2-1.
Djokovic has been bothered by a left shoulder injury all week, although it was not apparent during the opening two sets with Wawrinka reprising the sort of form which made him the champion in 2016.
But the Serbian took a medical time-out after dropping the second set, and three games into the third he decided enough was enough.
Meanwhile, Johanna Konta knocked out the third seed to reach a third successive grand slam quarter-final and her first in New York.
