Andy Murray says he could return to singles tennis action sooner than expected.
The former world number one has been easing back into the sport by playing doubles after having hip surgery in January.
Murray says he's hoping to play in the singles at the ATP event in Cincinnati next month.
This week he plays in the doubles at the Citi Open in Washington with brother Jamie.
