Andy Murray admits grand slam chances may never improve after US Open defeat

Andy Murray admits he may have to accept his days of competing in the latter stages of grand slams could well be over.

The 36-year-old former world number one bowed out of the US Open after a dispiriting second-round defeat to his old rival Grigor Dimitrov.

In the 12th meeting between two veterans of the sport, and seven years after their last one, 19th seed Dimitrov registered only his fourth win over the Scot.

Murray wilted inside the Arthur Ashe Stadium, the court upon which he won his first grand slam title in 2012, as he slipped to a 6-3 6-4 6-1 defeat.
