Rory McIlroy lashed out at the toughest golf course in the country Friday as Oakmont Country Club continued to bare its teeth at the 156 men competing in the 2025 U.S. Open.

Fresh from securing the career Grand Slam with a Masters win in April, McIlroy had set his sights on a sixth major title and a second US Open, having narrowly missed out to Bryson DeChambeau at Pinehurst No.2 the previous year.
