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 and reach 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 over 20
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 settled by a tie-break, recovered
to take the lead again.
