The first round of the 2025 U.S. Open lived up to the billing as Oakmont Country Club yielded only 10 rounds under par -- with an average score near 5 over par -- despite ideal conditions on Thursday. The round of the day belonged to J.J. Spaun, who shot a bogey-free 66, becoming just the second player to achieve that mark in the last three U.S. Opens at Oakmont dating back to 2007.
The only other man to accomplish that feat was Dustin Johnson (Round 1, 2016), and Spaun will now focus on ensuring the rest of his tournament goes as well as Johnson's did that year when he won his first major title.
While Spaun made Oakmont look pretty simple, the course showed its teeth to many of the world's best. Scottie Scheffler (73), Bryson DeChambeau (73) and Rory McIlroy (74) all struggled to get around Oakmont as the three players who led on the pre-tournament odds sheet coming all have plenty of work to do Friday if they plan to move into contention.
The star that performed best Thursday was Jon Rahm. The 2021 U.S. Open champion navigated his way around Oakmont for a 69 that included 14 pars, two bogeys, one birdie and an eagle on the par-5 4th. With that performance, Rahm became the betting favorite to win his second U.S. Open, leaping Scheffler, per BetMGM Sportsbook.
Also in pursuit of Spaun is another former U.S. Open champion in Brooks Koepka, who hasn't contended at a major since his last win at the 2023 PGA Championship. Koepka found his A-game seemingly out of nowhere Thursday, closing with a birdie on No. 18 to post 68 and sit just two back.
Friday will go a long way toward informing us whether the Koepka of old is back, the player who piled up five majors and briefly stood as the greatest competitor of his generation in such events. But at least for one day, he was again sensational to watch.
2025 U.S. Open leaderboard breakdown, Round 1
1. J.J. Spaun (-4): Spaun did all of his damage on his first nine after starting on No. 10, making four birdies to turn at 31. On his second side, he couldn't reproduce the same level of ball-striking but atoned for that with an unbelievable performance on the greens as he made six par putts from over 7 feet on the day -- four coming on his second side. Now the challenge is getting through another clean round at Oakmont, where it's often difficult to maintain that level of success on the greens.
2. Thriston Lawrence (-3): Lawrence made a double on No. 9 to turn at even par, but he rallied on the back nine with three birdies and no bogeys to move into second place. While Spaun has elevated himself into the top 25 in the world this season and pushed Rory McIlroy to a playoff at The Players, this is a far more shocking performance from Lawrence, who missed 7 of his last 8 cuts on the PGA Tour. However, he did have a fourth place finish at last year's Open, so this isn't entirely uncharted territory for the South African.
T3. Si Woo Kim, Brooks Koepka, Sungjae Im (-2): Kim played a fantastic round in the morning and then delivered the funniest quote of the day after shooting a 68 where only two other players beat him: "Honestly, I don't even know what I'm doing on the course. Kinda hitting good, but [I] feel like this course is too hard for me. So, kinda like no expectation, but I played great today."
We'll see whether Kim can find a way to play great again Friday, but he's not even putting pressure on himself to replicate that performance given the known difficulties Oakmont will throw his way. Joining him at 2 under is fellow countryman Sungjae Im, who had the solo lead at 5 under after 11 holes but gave three shots back coming into the clubhouse.
The other name at 2 under is Koepka. The two-time U.S. Open champion's success at difficult major tests used to make him a pre-tournament favorite at this event every year, but he's been a non-factor in majors of late and entered this week at 90-1. That made his 68 on Thursday surprising, but we all know how well Koepka can grind through a difficult U.S. Open setup. After the way he played Thursday, no one should be shocked if he's in the mix through Sunday.
T6. Jon Rahm, Thomas Detry (-1): Rahm is starting look like his old self again, and after a top 10 at the PGA, he's right back in the mix at Oakmont. His opening-round 69 has him as the new betting favorite, leaping Scheffler after the world's No. 1 struggled to a 73. Detry, Nicholas and Neergaard-Petersen round out the rest of the players that were able to get it in red figures on Thursday. Neergaard-Petersen was 3 under for much of his day and had multiple putts to tie the lead, but a tough closing stretch dropped him back.
T11. Jordan Spieth, Russell Henley, Adam Scott, Collin Morikawa and five others (E): It was a vintage Spieth rollercoaster round with five birdies and five bogeys, but he has to be encouraged by his ball-striking and a solid effort on the greens. Morikawa hit some stunning iron shots to set up birdies, but as is often his issue, he couldn't hole enough midrange putts to really make a move into red figures. Still, he's in good position after the first round; if he can get anything going on the greens, with his ball-striking, he will be a real threat. Then there are Scott and Henley, two incredibly consistent, steady player. It's no surprise to see them play a solid round, though Scott took a page out of Spieth's book with a wild scorecard on his first nine, including just one par.
T20. Viktor Hovland and 12 others (+1): There were times Hovland looked like the best player on the course, as he ripped off three birdies in a row in the middle of his round, but other times where he looked lost. That's a microcosm of Hovland's season, and he'll have to figure out how to clean up his card if he's going to contend this week.
T33. Ludvig Åberg, Xander Schauffele and 15 others (+2): Åberg made the turn at 2 under but had a disastrous close to his round with four bogeys in his last five holes to fall six shots off the pace. Schauffele, meanwhile, had the opposite journey to 2 over, as he struggled mightily until closing with back-to-back birdies to put a solid score on the card.
T49. Scottie Scheffler, Bryson DeChambeau, Patrick Reed and 13 others (+3): Scheffler and DeChambeau had high hopes coming in, but neither could string together much of anything positive. DeChambeau stumbled home with four bogeys in his final 10 holes after getting it to 1 under, while Scheffler made a number of uncharacteristic mistakes with six bogeys on his card. They're both still sitting near the top of the odds sheet, but they have little margin for error the next three rounds if one of them is going to win their fourth major title. Reed, meanwhile, earns an honorable mention for having an albatross and a triple bogey on his card, which I can't imagine has happened often anywhere.
T62. Rory McIlroy and 18 others (+4): McIlroy's day started off with so much promise as he made the turn at 2 under and looked in full control of his game. And then the wheels came off on the front nine (his second side) with a 6-over 41 that he capped with a double on the 8th. After his missed cut at the Canadian Open, McIlroy really needed to get off to a strong start to turn his mojo around; instead, he's left searching once again and with some work to do Friday to make the cut.
