SOUTHAMPTON, N.Y. — The USGA set up a different golf course at Shinnecock Hills to keep it playable in strong wind. And when the wind subsided late Thursday afternoon, Wyndham Clark looked like he was playing in a different U.S. Open.

Clark seized on a more gentle course — slightly calmer and still soft with receptive greens — by pulling away late to reach 6-under par through 16 holes.

He left in darkness with a four-shot lead over seven players, one of them Oklahoma junior Ryder Cowan, another one the surprisingly resurgent Dustin Johnson.

Rory McIlroy thought he had made a fine effort with a 69 in gusts that topped 30 mph in the middle of the day, when the scoring average was well above 74. The afternoon started tough until the wind kept subsiding, and players began taking aim at flags. The afternoon wave was playing at least a stroke easier than the early starters who faced relentless wind.

“Everything was kind of clicking,” said Clark, who came into the U.S. Open playing as well as anyone. “We were definitely fortunate with the wind laying down. Overall a good round.”

Shinnecock was still a brute of a test, but the red numbers on the white scoreboard was an unfamiliar site for this course. When play was suspended by darkness, 17 players were under par.

The lowest opening round in the previous five U.S. Opens at Shinnecock is 66, last done by three players in 2004.

Cowan birdied his last hole for a 68 to join former Sooner Max McGreevy and former Oklahoma State player Sam Stevens, the only one of that trio who faced the harsh wind of the morning wave.

Johnson, in his final year of being exempt from the U.S. Open he won at Oakmont in 2016, ran off four straight birdies and was tied with Clark after 13 holes. But Johnson failed to get up-and-down for birdie on the easy par-5 fifth, where Clark made eagle. And then Johnson three-putted from short range for double bogey on the sixth to fall four shots behind.

Scottie Scheffler, who needs the U.S. Open to complete the career Grand Slam, battled all day and relied heavily on his short game to salvage a 72. It was his 10th consecutive U.S. Open round without breaking par, but at the time it left him only four shots out of the lead.

Clark, who won the U.S. Open in Los Angeles three years ago, changed the look of the leaderboard. He was to return Friday morning to complete the round, then head out for the second round in wind expected to be not as strong.

One key to his round might have happened some five hours before he even showed up.

Thirty minutes after the round began, play was stopped because of fog so dense it was difficult to see the fairway and the green on the par-3 11th. The two-hour delay pushed back tee times.

The forecast was for the strongest wind of the week during the brightest part of Thursday.

“I would say when I got my tee times on Tuesday, I was like, ‘Oh, could be a tough draw,'” Clark said. “That two-hour fog delay was very helpful, and it was really nice it laid down. So it definitely helped those last six, seven holes we played.”

His golf wasn’t too shabby, either. Clark started on No. 10 and opened with two quick birdies. He went out in 32 to get his name atop the leaderboard.
