Momentum with Murray at US Open

The third seed faces Russia's Alex Bogomolov in the second match on the Arthur Ashe Stadium on the opening day.

The Briton, 25, is seeking to win his first major, having finished runner-up to Roger Federer at Wimbledon.

"I feel confident in myself just now. That's what's important," said Murray, who reached the US Open final in 2008.

"Winning the Olympics was the biggest win of my career, that's for sure. It meant a lot to me.

"But you never know what's going to happen when you get out there on the court. I've prepared well and trained hard, so I'm ready to go."

Murray suffered a fourth consecutive Grand Slam final defeat when he lost in four sets to Federer at Wimbledon but made up for that by defeating both Novak Djokovic and Federer in consecutive straight-set victories at the Olympics, BBC News reports.

However, the Scot has not had it easy going into this tournament. He suffered a minor knee injury at the Toronto Masters and a week later lost at the Cincinnati Masters in straight sets to France's Jeremy Chardy.

"I didn't really play much in Toronto, so I do not think it's going to have much bearing at all," he added.

"I went into Wimbledon this year having lost in the first round of Queen's. That was meant to be a horrible preparation, but Wimbledon worked out fine. So there's no reason why that can't happen here."
