SOUTHAMPTON, N.Y. — History holds a regular tee time at Shinnecock Hills Golf Club. Founded in 1891, it is the oldest incorporated golf club in the country. Inside a white tent just off the first fairway, Mike Davis, CEO of the USGA, considers the past ahead of the 118th U.S. Open to be held on site this week. He calls the course “a national treasure,” throws laurels at the aesthetics and notes the extended length — 7,445 yards to be played to a par of 35-35 — 70. He tracks the landscape’s evolution, referencing aerial views, fairway contours and shot values. Not all history is hallowed, though. Davis broaches the hell that still haunts the clubhouse. It was 14 years ago, during the final day of the 2004 U.S. Open, when the greens ran dry on No. 7.
