Andy Murray won a seventh Masters title as world number one Novak Djokovic retired from the Cincinnati final with a shoulder injury at 6-4 3-0 down.
It was only the second loss of the year for the Wimbledon and Australian Open champion, who has won 57 times in 2011. He received treatment between sets, but conceded defeat to hand Murray the title after netting a limp smash.It was an underwhelming end to a match that had promised to be a more thorough test of Murray's US Open credentials.
The Scot progressed to his first Grand Slam final at Flushing Meadows in 2008, straight after winning his first Masters title against Djokovic in Cincinnati the previous month. Hopes of a similar run for the British number one this year will have been raised by the fates of the three men above him in the world rankings in Ohio.
Roger Federer and Rafael Nadal both lost in the quarter-finals while Djokovic, who looked short of energy throughout the final, seems to be feeling the effects of his outstanding season.
