Five points about Chambers Bay

Tacoma - Five outstanding points about Chambers Bay golf course, Tacoma, the venue of the 115th US Open starting on Thursday:-

- The par-70 course has two holes - 1 and 18 - that can change daily from par-4s to par-5s. But for the US Open if one is a par-4 then the other is a par-5, maintaining the overall par at 70

- The course was only opened eight years ago on the site of a disused sand and gravel quarry. It was designed by Robert Trent Jones Jnr and is a rare example of a true US links course.

- Chambers Bay has oddly sloping tee zones - some sloping sideways and other downways or upways

- The yardage can vary from 7,200 yards to over 7,600 yards depending on the weather and wind conditions coming in off the Puget Sound.

- It will be the first course in the US Northwest Pacific to host a US Open and the 13th on the Pacific Coast, the last being The Olympic Club in San Francisco in 2012.
