US Open 2015: Andy Murray feels in great shape for New York

Andy Murray feels he has never gone into the US Open in better shape after a month of good form.

Murray made the semi-finals of the Cincinnati Masters before defeating Novak Djokovic in the Rogers Cup final.

However, he faces a tough test in New York with Australian Nick Kyrgios his opponent on Tuesday.

"I believe I can win. I've played well enough this year to give myself an opportunity at all of the majors," he told BBC Scotland.

"Coming in here in the past few years I didn't necessarily have great preparation. I haven't played particularly well in Cincinnati or Canada over the past few years, and in 2012, I hardly played any matches on the hard courts coming in (because of the Olympics).

"I definitely feel like my body is in a good place and I've obviously won more matches this year than I have in the past, so I feel good going in."

Murray was a winner in New York in 2012 with a five-set victory over Novak Djokovic, and was also a winner in 2004 when he won the junior US Open.

The 2013 Wimbledon champion is looking for his third career major after finishing as runner-up in the Australian Open and making the last four of both the French Open and Wimbledon this year.

"Players tend to play well at the same places throughout their career and I always enjoy the tournament," he said.

"It's meant to be hot and humid so that will be challenging, but I normally like the courts here and the balls they use here are different to the ones in Cincinnati and Canada.

"I feel good and I'm looking forward to getting going.

"I've lost some close matches this year and I do feel like I'm playing a little bit better now than I was at the beginning of the year. But things can change and if I show up and have a bad day on Tuesday I'll be out of the event, so I need to just stick to what I've been doing and not get ahead of myself."

Third-seed Murray admits the conditions will suit Kyrgios, the world number 37.

He said: "It's a tough one. I've had some tricky ones over the year. Nick loves these conditions and likes a big stage."
