Andy Murray is confident the injury which interrupted his US Open preparations has cleared up just in time for the main event.
The three-time grand slam winner, champion at Flushing Meadows in 2012, had to withdraw from this year’s warm-up tournaments in Toronto and Cincinnati.
Murray, 36, was unable to serve in practice until this week due to what he revealed turned out to be a torn abdominal muscle.
“The first five or six days were a bit complicated. There were lots of different opinions,” said the Scot.
“It is quite a difficult place to scan, the ab, so we weren’t really sure the first few days. And then I came to New York pretty early and went to one of the hospitals here and had the radiologist from back home who looks at my scans check them.
“I had a small tear, which is healing. And the last five or six days of practice have been really good. I have not had any issues serving.
“It is just obviously that you don’t take a week off from serving then go full into it. You need to build up a little bit. It has not been perfect in that sense but my ab has been OK.”
