Seventy-two holes of struggle await the eventual 2025 U.S. Open winner as Oakmont Country Club is prepared to bare its teeth for a 156-man field all seeking to claim the national championship. The par-70 course is hosting the USGA's signature tournament and the third major championship of the season for a record 10th time with golfers attempting to transverse its difficult landscape for the first time in nine years.

The first round of the U.S. Open was played under sunny skies and no rain at the Oakmont Country Club on June 12. The field might not be as lucky for the second round. The weather forecast calls for more of a rain chance, especially between Noon and 5 p.m. According to weatherunderground.com.

Highlights from historic Oakmont Country Club, home of the 2025 U.S. Open, golf's third major tournament of the year.

Scottie Scheffler, Rory McIlroy, Xander Schauffele and reigning national champion Bryson DeChambeau have combined to win the last six, and one of them may well extend that streak to seven this week at the 2025 U.

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.

Spaun went out in a record 31 and posted just the eighth bogey-free round in U.S. Open history at Oakmont to take the early lead on Thursday.
