Wyndham Clark builds an early four-shot lead at the U.S. Open following a weather-affected first day at Shinnecock Hills. Multiple reports describe difficult conditions, with winds disrupting play and a later easing of conditions as the round progresses. Against that backdrop, Clark posts steady scoring that places him at the top of the leaderboard heading into subsequent rounds. Rory McIlroy is also in contention, with outlets noting a strong start and an impressive performance during the opening day. Scottie Scheffler remains in the hunt as well, with coverage characterizing his round as challenging but keeping him in contention for the tournament. The first day’s results are shaped by the weather, with one report noting that darkness brings the first round to a halt, contributing to an uneven flow of play. Overall, the sources converge on Clark’s lead, McIlroy’s early form, and Scheffler’s ability to stay within range despite the tougher conditions.
