Murray receives treatment during his defeat to Djokovic

Murray, whose hip was injured in his quarter-final on Friday, was broken five times in total as he lost 6-2 6-3.

Murray said: "After the first couple of games, I realised that when you can't change direction and when the movement is missing, it's quite hard to play."

Rafael Nadal beat home favourite Andy Roddick 6-4 6-3 in the other semi.

Murray later admitted he considered withdrawing from the match while he received treatment.

But he said: "I spoke to the trainer and he said: 'you're not going to do more damage (to the ankle) by playing.'

"If I didn't go on the court, that would have been fine, but when I did go on, I might as well have played the match because it's not like it was going to get worse."

The world number 13 admitted he was still aching from the injuries sustained in his quarter-final against Haas and said he had not slept well the night before.

He added: "Every single place I moved to, whether it be my elbow, or the cut on my knee, just felt pretty uncomfortable.

"None of them were really bad. It's just when you have four or five small injuries, it's kind of difficult to compensate."

I played good mentally Rafael Nadal

After suffering with injuries and a loss of form in the second half of 2006, Nadal has rediscovered his game.

The 20-year-old made 33 winners and only 12 unforced errors as he saw off Roddick in one hour 13 minutes.

He broke Roddick's serve three times in their match, moving ahead in game five and breaking twice more in the second set.

And the Spaniard made an impressive 87% of first serves.

"I am serving well," said Nadal. "Not as fast as him but I changed it up, to the side and down the middle. I played good mentally."
