US Open officials have refused to echo the thoughts of some golfers who are unhappy with the layout of the course at Chambers Bay.

The Washington course, which was built on land that was previously used as a rock quarry, has troubled some of this week's competitors due to its firm and dry surface.

Despite concerns, United States Golf Association director Mike Davis believes that the course meets all expectations for the Major tournament.

"From a set-up standpoint and really presenting the golf course for a championship test, we couldn't be happier," Davis told reporters. "While it's going to be different, we are going to remain true to really what a US Open is and what it's been.

"[It's] a great comprehensive test of shot-making skills, course management skills, ability to handle your nerves and there's a bit of an endurance test."

Reigning champion Martin Kaymer has been paired with world number one Rory McIlroy for the first two rounds.
