Murray was whitewashed in the fourth set

Trailing two sets to one overnight after rain brought a halt on Tuesday, the Scot was swept aside in quick time.

He served three double-faults to lose his opening service game, and another saw him fall 3-0 down.

Davydenko broke again for 5-0 to cruise into his third Grand Slam quarter-final this year, triumphing 6-1 5-7 6-3 6-0.

The bad weather appeared to have come at a good time for Murray on Tuesday, who had just seen Davydenko come from a break down to clinch the third set 6-3.

The Russian had begun the match in blazing style, breaking Murray three times as he took the opening set 6-1.

But the 19-year-old hit back to take the second set 7-5 and raced to a 2-0 lead in the third before dropping five games in a row.

But he was miserably out of touch when the match resumed, ending it visibly frustrated with a volley of verbal outbursts, apparently to himself.

There's absolutely no disappointment at all. I had a great summer Andy Murray

Murray admitted afterwards that he needed to button his lip more on court.

"When I get nervous, maybe I speak a little too much. Something that hopefully I'll stop because it's definitely not good for my tennis," he said.

"He started off better than me both days. That's something I'll have to learn from. I'm not used to going on at 11am for matches."

But Murray was satisfied with his performance, saying that Davydenko had simply been the better player.

"Sometimes you just have to say, 'Too good', and he was too good today," said Murray. "He was just playing the big points better than me.

"There's not too much I could have done. If he plays like that for four or five sets, he's got a good chance of winning the tournament."

And as his Grand Slam activity for 2006 comes to an end, Murray said he was more than satisfied with his progress.
