It is currently raining at Flushing Meadows, so this match has been delayed until the deluge subsides.

Murray has already changed his racquet three times. He'll be wanting to select the perfect tension. The Scot has also enquired to the referee about Young's late appearance on court - putting his lower ranked opponent in his place. Will it work? We'll see...

Young has now appeared on court to a fairly large ovation. He takes no notice at all. He looks focused - as he will need to be. The two players are just about to knock up.

Andy Murray has made it onto court but Donald Young is still inside. The drizzle has also become slightly heavier. Nothing to worry about though. Not just yet.

Andy Murray has left his dressing room and is making his way towards Grandstand Court. The weather folks are not too sure how long this 'window' of playing time will last, but at least we'll get to see some tennis!

Don't forget, you can watch the US Open LIVE on British Eurosport and Eurosport HD (Sky 410/412, Virgin Media 521)! We'll keep you updated about specific matches...

Britain's Andy Murray reached the fourth round with a rather convincing victory over the very tricky Feliciano Lopez, but will face a different prospect completely today as he faces home favourite Donald Young.

The word going around Flushing Meadows is that Andy Murray and Donald Young will make their way onto court in around ten minutes time. Fingers crossed!!
