Rory McIlroy and Patrick Cantlay are co-leaders after the first round of the U.S. Open at Pinehurst No. 2, both carding impressive 5-under 65s. McIlroy, seeking his first major since 2014, showcased excellent control and a bogey-free round, while Cantlay finished strong with a series of birdies. Despite a solid start, McIlroy struggled in the second round, finishing with a 2-over 72, but remains in contention. Scottie Scheffler, the world No. 1, is at risk of missing the cut after a disappointing 74. Bryson DeChambeau and Thomas Detry are also in the mix, with DeChambeau finishing the second round at 4-under. The challenging Pinehurst course continues to test the players, with many struggling to maintain consistency.
