Rory McIlroy expressed satisfaction with slower green speeds during the first round of the U.S. Open, acknowledging the difficult, windy conditions at the course. Despite the favorable adjustment, McIlroy’s performance was mixed, achieving a 1-under par 69. He briefly held the lead on two occasions but was unable to maintain it, missing opportunities to capitalize fully. The challenging conditions impacted several players, making consistent scoring difficult. McIlroy remains a contender, but will need to improve his putting to secure a higher position on the leaderboard. The slower greens were implemented to counteract the strong winds and maintain fairness.
