SOUTHAMPTON, N.Y. The 2026 U.S. Open began on Thursday morning and did not finish until Friday afternoon, not because the field was deep in drama but because fog held the course hostage at dawn. The suspension lasted two hours. That evening, with lightning approaching from the west and 50 players still waiting to tee off, darkness called the day to a halt as well. The first round was completed Friday morning under cleaner skies and calmer winds, but by then the tournament's essential fact had already been settled. Wyndham Clark, the 2023 U.S. Open champion, had signed a 6-under 64, the second-best round ever posted at Shinnecock Hills in a U.S. Open and only one stroke shy of Tommy Fleetwood's 2018 course record of 63.
It was the kind of opening that makes a U.S. Open lean back and listen.
The champion's statement
Clark has won this tournament once, in 2023. On Thursday he played like a man remembering exactly why. He navigated Shinnecock Hills, a course that punishes imprecision as a matter of policy, without a single bogey. His score of 64 equals his best round ever at this major championship, matching his opening 64 from 2023, and it comes at an age (32) and stage of a season where most of his peers have already tipped their hand.
The arithmetic is worth holding: this is Clark's eighth career 18-hole lead or co-lead on the PGA TOUR, and he has converted exactly none of the previous seven into a win. That statistic stings, particularly here, where he proved capable of winning on the grandest stage and then proved incapable of learning to do it again. But he had converted a 36-hole lead into a title at the 2023 Truist Championship earlier in his career, and more recently he closed with an 11-under 60 to win the CJ CUP Byron Nelson just a month ago. The pattern on his record no longer reads as inevitable.
The field fractures
Two shots back at 4-under sits a single player, Dustin Johnson, the 2016 U.S. Open champion and a man whose major championship credentials remain impeccable despite the years in between. His 66 on Friday morning was clean and professional, the round of someone who knows exactly how the test tilts.
Three shots behind Clark, at 3-under, sits a pair worth watching closely through the weekend. Matt Fitzpatrick, the current FedExCup leader and the only player on TOUR with three wins already this season, opened with a 67 and remains within striking distance. Gary Woodland, the 2019 U.S. Open champion, matched him at 3-under. Both have won at the highest level at this golf course. Both will believe they can do it again.
Further back, at 2-under, sits a five-man cluster that includes two names of particular importance. Jon Rahm, the 2021 U.S. Open champion, posted a 68 that was clean in a specific way: it contained no bogeys, the first bogey-free round at a U.S. Open at Shinnecock Hills since 2004. Ryder Cowan, an amateur, opened with the same score, becoming the first amateur to crack the top five on a U.S. Open leaderboard after any round since 2015. And Sam Stevens, still searching for his first PGA TOUR victory in his 116th career start, matched them both at 2-under.
The shot that echoed
Not every round finds a moment that defines it. This one did, though it belonged to a player well outside the lead. Keith Mitchell, in a tie for 17th at even par, closed his round with a 6-under 29 on the front nine (Nos. 1-9), equaling his best nine-hole score in 231 TOUR starts. It tied Neal Lancaster's U.S. Open mark at Shinnecock (set on the back nine of the 1995 fourth round) and announced clearly that the golf course, for all its teeth, will reward the patient and the precise.
In the same register, Tommy Fleetwood, the defending FedExCup champion, opened with an even-par 70, five strokes better than the 75 he posted en route to a runner-up finish in 2018. The comparison itself was instructive: two veteran major championship players approaching the same venue from opposite directions, one climbing, one defending.
The champions at rest
Twelve past U.S. Open champions are in the field, a weight of history that this tournament carries unlike any other. Of those twelve, six have positioned themselves at 10th or better through one round. Beyond Clark and Johnson and Fitzpatrick and Woodland sits Rory McIlroy, the six-time major champion, tied for tenth at 1-under. His 69 represented an 11-stroke improvement over his opening round here in 2018, when he posted an 80, one of his worst scores in a major championship.
Scottie Scheffler, the world's top-ranked player and seeking his fifth major championship, sits at 2-over and comfortably inside the cut line. He is here for something larger than this week: one victory away from completing the Career Grand Slam. Brooks Koepka, attempting to join an exclusive list of three-time U.S. Open winners, sits at 3-over alongside Adam Scott, who is making his 100th consecutive major championship start.
The cost of imperfection
On the other end of the ledger, J.J. Spaun, who arrived as the defending U.S. Open champion, opened with a 77, the highest first-round score a defending champion has posted at this event since Rory McIlroy's identical 77 in 2012. He sits at 7-over, well outside the line. Joaquin Niemann posted an 8-over 78 and drew two penalty strokes for throwing a club on the sixth hole.
What Saturday demands
A U.S. Open at Shinnecock Hills plays harder on Friday than it did on Thursday, not because the course changes but because the leaderboard instructs the wind and the greens on what to do. A 64 leads by two. A 66 trails by two, a 67 by three. Everything short of 2-under sits outside the conversation. The cut, when it comes, will land well south of where it fell at Merion or Torrey Pines, and it will land there because Shinnecock Hills has no interest in widening the field.
Clark's lead is two shots, slender in a major championship. Johnson must stay close or watch it grow. Fitzpatrick and Woodland will need to think par is a loss, not a win. And the twelve past champions, the amateurs, the long shots: each will wake Friday with the same elementary arithmetic. Shoot low, or go home.
Shinnecock Hills has seen 64s before. It waits to see who can follow them.
