History not on the side of the world's top golfers after Round 1 of U.S. Open

Thriston Lawrence (-3) is one shot back, while Brooks Koepka, Si Woo Kim and Sungjae Im (-2) are tied for third.

Aside from the five-time major winner Koepka, the other four have a combined seven wins. Lawrence has never won a PGA Tour event and is the No. 90 player in the world, while Im is the highest-ranked player of the four at No. 23.

Other than Koepka and Jon Rahm, who is a two-time major winner, there is not much star power under par after the opening round of the third major this season.

The top-ranked golfer and three-time winner this season, Scottie Scheffler, finds himself at +3 and tied for 49th after a first-round 73 that featured three birdies and six bogeys.

Even farther down the leaderboard are 2025 Masters champion and No. 2 player in the world Rory McIlroy (+4, tied for 62nd) and the No. 5 player Justin Thomas (+6, tied for 98th).

The defending U.S. Open champion and No. 10 player in the world, Bryson DeChambeau, sits at +3 and in a tie for 49th with Scheffler.

All four find themselves at least seven shots behind Spaun after Round 1, and history suggests they will have a long road ahead of them. According to The Athletic, nobody has won the U.S. Open from that far back after the opening round since Lee Janzen in 1998. It has only happened three times in the last 60 years.

With only 10 players breaking par on Thursday, it is clear how treacherous the course is playing. Looking at the history of previous U.S. Open's at the unique course, that should not be a surprise.

According to Jay Busbee of Yahoo Sports, there have been nine U.S. Open's played at Oakmont prior to this year and only 28 of the 1,385 players who have competed in those events have finished under par.

That does not bode well for the stars of the sport who enter the second round on Friday multiple shots over par. No one is safe at Oakmont, but an early deficit will force them to play from behind at one of golf's toughest courses.
