Losing yet another grand slam final doesn't bear thinking about for Andy Murray, who is instead vowing to crown his golden summer with a long overdue maiden major at the US Open.

Murray can stake his claim for player-of-the-year honours with victory over either defending champion Novak Djokovic or Spanish fourth seed David Ferrer in tomorrow morning's delayed final at Flushing Meadows.

The alternative is a dubious place in tennis history as the first man ever to lose his first five grand slam title deciders.

The shattered Scot was reduced to tears after succumbing to Roger Federer at Wimbledon and admits another defeat on one of sport's greatest stages would be soul-destroying.

''You saw obviously at Wimbledon how much that meant to me. It's obviously not easy to lose another slam final, so I hope this one is a different story,'' Murray said after overcoming extraordinary wind gusts to beat Tomas Berdych 5-7, 6-2, 6-1, 7-6 (9-7) in his semi-final.

Yesterday's second semi was suspended amid a tornado warning in New York, with Ferrer leading Djokovic 5-2 in the first set.

With an extra day's rest before the final, it was advantage Murray before a ball was even hit in the championship match.

''I have been in the position before when I played in the final where I didn't get the day off and maybe it hurt me a little bit,'' said Murray, who lost the 2008 final to Federer in straight sets.

With winds estimated at 100km/h an hour having a chaotic effect at times on Berdych's unusually high ball toss, the Czech claimed their match should have been stopped. But while describing the brutal conditions as the toughest he'd ever played in, Murray wasn't so sure.

''There is a skill to playing in the wind,'' he said.

''Who knows what the right decision was. I'm just glad that I was the first match today and got it done.'' Tomorrow's final starts at 6am Canberra time. AAP
