2025 U.S. Open Championship: 10 Things to Know: Round 1

The 125th U.S. Open at Oakmont Country Club is underway and today's first round of play presented a challenging test.

The scoring average in Round 1 was 74.63, which was the highest first-round scoring average at a U.S. Open since 2018 at Shinnecock Hills (76.47).

Here are 10 things to know about round 1.

1.  JJ Spaincame out blazing, shooting 31 over his first nine holes (on the inward side). It was the lowest first nine holes ever played at a U.S. Open at Oakmont CC.  The previous best was 32, by Gary Player (1973), Jumbo Ozaki (1994) and Scott Piercy (2016).

2.  Spaun's first round score of 66 matched the lowest first round score at a U.S. Open at Oakmont CC. Andrew Landry opened with a 66 in 2016.

3.  Spaun was the only player to go bogey free in the first round on Thursday. He is the eighth player to have a bogey free round at a U.S. Open at Oakmont CC. The most recent player to do that was Dustin Johnson, in the first round of the 2016 Championship (which he went on to win).

4.  Brooks Koepka, who finished tied for third in the first round on Thursday, snapped a streak of 28 consecutive major championship rounds in which he finished outside the top 10 on the leader board. It began right after his PGA Championship win in 2023 at Oak Hill CC; and it was the longest such drought of his career.

5.  Jon Rahm shot 69 in the first round on Thursday, marking his 10th sub-70 round at a U.S. Open since 2019. The only players who have as many rounds in the 60s at the U.S. Open since 2019 as Rahm are Rory McIlroy (14) and Bryson DeChambeau (12).

6.  This is the fifth time that both Brooks Koepka and Bryson DeChambeau will be among the top-10 together at the conclusion of the first round of a major championship. That last occurred at the 2023 Masters.

7.  Patrick Reed holed the fourth albatross in U.S. Open history, carding a 2 on the par-5 fourth hole. The last player to do that in any major championship was Nick Watney at the 2012 U.S. Open at The Olympic Club.

8.  Scottie Scheffler, playing in his 24th career major championship, shot the highest first round score relative to par (+3) in his majors career. It was the fifth time in 87 career major championship rounds that he made as many as six bogeys (or worse).

9. a) The scoring average in Round 1 was 74.63, which was the highest first-round scoring average at a U.S. Open since 2018 at Shinnecock Hills (76.47). b) 10 players finished under par in Round 1, which is one fewer than the number of sub-par opening rounds at the 2016 U.S. Open at Oakmont CC.

10.  Two players representing Korea (Si Woo Kim and Sungjae Im) are tied for third. It is the just the third time a pair of players representing Korea are among the top 3 on the leader board at the conclusion of a major championship round. That also happened with K.J. Choi and Y.E. Yang in the first round of both the 2010 and 2011 Masters.
