Andy Murray has reached his first Grand Slam final after beating world number one Rafael Nadal.

The Scot ground out a 6-2 7-6 4-6 6-4 victory at the US Open in a semi-final that began on Saturday and ended more than 24 hours later after being interrupted by Tropical Storm Hanna.

Leading by two sets but trailing 2-3 in the third overnight, Murray lost the third set before breaking the Spaniard in the tenth game of the fourth.

He wrapped up the biggest victory of his career with a backhand winner, ending a five-match losing streak against Nadal.

The 21-year-old will play four-times defending champion Roger Federer in Monday's final.

The victory makes Murray the first British Grand Slam men's singles finalist since Greg Rusedski reached the US Open final in 1997.
