Novak Djokovic sets up US Open semi-final showdown with Kei Nishikori
NOVAK DJOKOVIC will face Kei Nishikori in the US Open semi-final after a gruelling win over John Millman.
After Millman knocked out the Swiss legend Roger Federer in the fourth round, he was expected to be an awkward opponent.
Millman tested Djokovic for over three hours and there were some long points, with one point producing a 27-shot rally.
Djokovic appeared to struggle at points in the match and even had a 10-minute break with the humidity getting to both players.
Djokovic has reached the semi-finals in each year he has played at the US Open since 2007 so he will fancy his chances against Nishikori.
Djokovic admitted after the match that he was thankful for the break when Millman went off court to change shirts.
The Serbian paid tribute to his opponent and he is once again through to the last four of a Grand Slam.
Should he win the US Open, he will be behind just Federer and Rafael Nadal in the world rankings.
