The world tennis number four Andy Murray has won the final of the Cincinnati Masters over Serbia's world number one Novak Djokovic, who retired injured.
Murray was leading 6-4 3-0 when Djokovic, who had received treatment to his right shoulder at the end of the first set, called it quits.
It was just the second defeat this year for Djokovic, whose victories this season included the Australian Open and Wimbledon.
