Novak Djokovic smash past Stanislas Wawrinka in New York after five-set

Novak Djokovic twice had to come from a set down to see off Stanislas Wawrinka 2-6 7-6 (7/4) 3-6 6-3 6-4 on his way to reaching the final of the US Open for the fourth successive year.
The Serbian was pushed to the limits by the ninth seed in a titanic battle on Arthur Ashe that included one game that lasted 21 minutes.

Wawrinka, who had knocked out reigning champion Andy Murray to reach the last four, took the opening set 6-2 and despite letting slip a lead in a second that was eventually lost on a tie-break, recovered to move ahead again.
Crucially, though, the Swiss was unable to put the top seed away, with Djokovic taking the fourth set 6-3 and then gaining a crucial break in the decider.
"These matches are what we live for, what we practise for," said the 12-time grand slam finalist after a match that lasted four hours and nine minutes.
