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.
