Former champion Wyndham Clark has seen his four-shot overnight lead halved as the first round of the US Open concluded early on Friday morning at Shinnecock Hills.
Clark, the 2024 victor and one of four previous winners occupying the top four places heading into round two, parred his remaining two holes after returning at 6.35am local time to sign for a six-under-par 64.
Dustin Johnson, a winner at an equally-tough course in Oakmont in 2016, rolled back the years to post a 66 after he birdied two of his final three holes to move into second place.
The 41-year-old American, who plays on the LIV Golf circuit, has missed six cuts in his last 11 majors with a best finish of joint-23rd but was one of Thursday's late starters to benefit from the absence of forecasted high winds to leave the course at the most vulnerable it will be all week.
