Britain's Andy Murray says he is fit and raring to go as he targets a maiden Grand Slam title at the US Open.

SIS supported athlete Murray struggled in the heat in his last tournament in Cincinnati, losing to Mardy Fish in the quarter-finals.

Murray said "I've had a good few weeks so in terms of match fitness I feel good."

The world number four, was a losing finalist at Flushing Meadows in 2008.

He enters the fourth and final Grand Slam of the year in good form having defended his Masters title in Toronto earlier this month, beating Nadal and Federer in consecutive matches.

"It definitely helped, it was good for the confidence," said the 23-year-old Scot.

"I always enjoying playing here, New York is obviously a fun city to come to. I've been here a week now and I feel good." 

Murray will not play his opening match in New York against Lukas Lacko until tomorrow. (Wednesday 1 September)
