In the opening round of the Aramco Championship at Shadow Creek in North Las Vegas, Lauren Coughlin showcased her familiarity with the course by shooting a 5-under 67, putting her in a three-way tie for the lead alongside Nasa Hataoka and Women's British Open champion Miyu Yamashita. Coughlin's prior experience at Shadow Creek includes playing 127 holes in last year's match play format, where she finished as the runner-up. This year's tournament features a total purse of $4 million and has shifted to stroke play, attracting a strong field of top players from the women's world rankings. Nelly Korda and Hyo Joo Kim both finished the round at 68, with Kim aiming for her third consecutive win after victories in the previous two weeks. Despite the challenging nature of Shadow Creek, 10 players managed to break 70, indicating a competitive atmosphere as the tournament progresses.
