NEW YORK (Reuters) - World number one Novak Djokovic wore down his old foe Andy Murray in a typically gruelling encounter under the lights at Flushing Meadows on Wednesday to reach the semi-finals of the U.S. Open.
In a repeat of the 2012 final, which Murray won, the pair combined for some stunning long rallies before Djokovic pulled away for a 7-6 (1) 6-7 6-2 6-4 victory to set up a semi-final against Kei Nishikori of Japan.
