Andy Murray Sets Up Semifinal with Rafael Nadal at US Open

Andy Murray has produced his best-ever Grand Slam performance by reaching the US Open semifinal, but he's not finished yet.

The sixth-seeded Scot may have failed to trouble Rafael Nadal in five previous attempts, but Murray is in the form of his life right now and maybe, just maybe, Nadal isn't.

Juan Martin Del Potro (19) was always going to be tough opposition. The Argentinean went into the quarterfinal off a 23-match unbeaten run.

Britain's No. 1, as I mentioned, is on top form and won through 7-6 (7-2), 7-6 (7-1), 4-6, 7-5.

What is really impressive about Murray is the way he seems to be finding shots and his form when he needs them most. He's been on the ropes countless times at Flushing Meadows and in previous hard court tournaments, but for the first time is pulling through and not folding under the pressure.

Add to that his demolition job of 10th seeded Stanislas Wawrinka 6-1, 6-3, 6-3 and there is certainly some cause for optimism amongst the Brit's fans.

Is the new grown up Andy Murray good enough to beat Nadal for a place in his first Grand Slam Final?

Well only time will tell, but I'd say it's his best chance yet.

No matter the result against Nadal, Murray will be up to fourth in the world rankings!

Maybe the thought of his big brother Jamie's securing his second Grand Slam Final title before he has his first is spurring him on?

Jamie Murray and Liezel Huber are in the mixed doubles final at Flushing Meadows, and the older Murray (22) already has a mixed doubles Wimbledon title to his name.

Time for some catching up, Andy!
