Djokovic in QF after Wawrinka pulls out
Defending champion Novak Djokovic finally made it through to the quarter-finals of the US Open after Stanislas Wawrinka retired in the third set of their match at Flushing Meadows
The pair had begun their fourth-round clash on Tuesday night before rain brought a premature end to play and they were on and off the court again before the match finally resumed just after 1pm on Wednesday.
Djokovic was tested in the first set but after that it was a one-sided contest and Wawrinka called it a day with the second seed leading 6-4 6-1 3-1, although the reason was not immediately apparent.
They managed only two games before the rain came on Tuesday, Djokovic winning both of them, but Wawrinka quickly retrieved the break on the resumption.
