British number three Andy Murray is nursing a shoulder injury going into the US Open at Flushing Meadows.
Murray is the youngest Briton ever to qualify for a Grand Slam and will face Andrei Pavel in the first round.
The 18-year-old was visibly struggling when his final qualifying match against Ecuador's Giovanni Lapentti went to a tie-break on Friday.
"The shoulder got worse as the week went on but it was something I had to put to the back of my mind," he said.
"The US Open is a tournament I have always dreamed of playing. So if I was feeling sore, it was not going to make a difference."
Murray, who won the US Open junior title last year, admitted it was his "favourite tournament".
