The golf world is getting ready to descend upon Oakmont Country Club in Pennsylvania for the third major event of the 2025 season: the U.S. Open. The U.S. Open will feature a field of 156 golfers vying to take home the title.

The U.S. Open is not only returning during a year when golf saw its largest Masters audience since 2018 with nearly 20 million viewers, but it's also coming back to one of the most notoriously difficult courses in the nation: the Oakmont Country Club in western Pennsylvania.

Unheralded J.J. Spaun outshined the game's top players and led the U.S. Open by one shot after the first round on Thursday at steamy Oakmont Country Club where the big names like Scottie Scheffler, Bryson DeChambeau and Rory McIlroy all struggled.

J.J. Spaun is still new enough to the U.S. Open, and a newcomer to the brute that is Oakmont, that he was prepared for anything Thursday. He wound up with a clean card and a one-shot lead on an opening day that delivered just about everything.
