Rory McIlroy opened his US Open campaign at Shinnecock Hills with a solid one-under 69, but Wyndham Clark seized the first-round spotlight with a six-under 64 that gave him a four-shot lead. The 2023 champion carded five birdies and an eagle through 16 holes before darkness halted play, demonstrating why he remains a formidable threat on the major stage.

Strong winds and early fog created a two-hour delay, with only six of 78 early starters breaking par on the 7,440-yard layout. McIlroy's round included a wind-assisted 396-yard drive and an eagle on the par-five fifth, though bogeys on 13 and 16 prevented him from challenging for the lead. The afternoon wave benefited from calmer conditions, with 11 of 17 players under par coming from the later starters.

World number one Scottie Scheffler struggled to a level-par 70, finding Shinnecock's undulating greens and five-inch rough unforgiving. Defending champion Brooks Koepka posted a 73, while Tommy Fleetwood managed a 70 alongside McIlroy. The USGA's course setup drew praise after learning from 2004 and 2018 criticisms, watering greens to maintain playable conditions.

Historical context looms large: only 9% of rounds at Shinnecock have been under par in the last four US Opens, with just three players finishing sub-par after 72 holes. McIlroy's measured approach reflects the venue's brutal reputation, making his opening 69 a respectable result that keeps him in contention without signaling dominance.
