Djokovic beats injured Cilic to reach US Open final
Novak Djokovic of Serbia celebrates after defeating Marin Cilic of Croatia during their Men's Singles Semifinals match on Day Twelve of the 2015 US Open
World number one Djokovic will play for revenge in the Sunday final when he faces the winner from five-time New York champion Roger Federer.
Federer lost the Wimbledon final to Djokovic but thrashed the Serb in last month's Cincinnati final.
Djokovic was unstoppable against an injured Cilic - the Croatian was carrying an ankle problem - winning the first two sets in barely three-quarters of an hour as the big man's 12-match win streak at the Open was ended.
Cilic absorbed a 14th straight defeat against Djokovic, whom he has never beaten.
"Marin was courageous to come out and finish the match today," said Djokovic, who will play his 16th final from the last 21 grand slams. "It's not easy to know that your opponent is not at 100 per cent. Still, I had to come with a good focus and intensity and executed the game plan."
The day marked the first time that four grand slam winners have played in the semis at Flushing Meadows since 1995, when Pete Sampras, Andre Agassi and Jim Courier and Boris Becker collided.
Djokovic polished an outstanding 2015 record by reaching the final at all four majors in the same season.
"It's a great achievement - I'm proud of it," said the 28-year-old Serb. "These are the events where you want to perform your best. I've not been very successful, here, winning one title but losing four times in finals. I'll give my maximum in the final."
Djokovic earned his 60th win in New York, advancing in an hour and a quarter with eight breaks of his hampered opponent.
