Ludvig Aberg and Hideki Matsuyama hit brilliant tee shots on the par three but neither can drain their birdie putt from inside 10 feet.

Adam Scott is a mile away in comparison, but lags a putt within a couple of feet to save par.

One player going under the radar is Thriston Lawrence but he's leading the chasing pack at the moment.

That's a fine birdie putt he's just slotted at his second hole and he's up to four under par, one back from JJ Spaun.

World number one Scottie Scheffler, speaking after his one-over 71 put him at four over par for the tournament:

"Mentally this was as tough as I've battled for the whole day. It's challenging out there.

"I was not getting the ball in the correct spots and paying the price for it. Felt like me getting away with one over today wasn't all that bad. It could have been a lot worse.

"I'm definitely not out of the tournament. With the way I was hitting it, today was easily a day I could have been going home and battled pretty hard to stay in there. I'm four over. We'll see what the lead is after today.

"At the US Open I don't think you're ever out of the tournament. Put together two decent days, I may be in 25th or 30th place or something like that after today, and like I said, by no means is that out of the tournament."

No mistake with JJ Spaun's birdie putt - the American now leads the field by two strokes.

He couldn't really have wished for a better start.

A good up-and-down from the greenside bunker from Ludvig Aberg but it can't prevent the Swede dropping a shot at the fifth.

Adam Scott also makes a bogey, his second in a row, and after a super start he's now back to one over.

A fully deserved birdie for Bryson DeChambeau after that monster lag putt did the trick on the par five, and that evens out his card for the day.

A nice birdie here also for Jose Luis Ballester as well, the young Spaniard who has just joined Jon Rahm's LIV Golf team as he gets it back to six over as he chases the cut line.

Oooof, a beauty of a tee shot to the par-three sixth from JJ Spaun, who will have an eight-foot putt shortly for a two-shot lead.

There are 15 amateurs in the field for this year's US Open and American Jackson Koivun is performing by far the best of any of them so far.

A perfect start with a birdie on the first - his approach landing within a foot of the hole - puts him one over for the tournament and on the fringe of the top 10.

If JJ Spaun has any nerves leading a major championship, he's not showing them.

A comfortable two-putt par on the fifth and he remains one shot clear of the rest.

Rory McIlroy does not go the route that did for Collin Morikawa and Daniel Berger earlier, opting to shuffle out to the left.

His ball sticks to the putting surface but he's now putting for bogey from 12 feet. A slow ponderous stroke wanders left and it's a second double in three holes.

Golf shot! Bryson DeChambeau is just off the front of the 12th green in two, but has a long, long way to go to this back pin, with a ton of break as well to nevigate as he decides to go with the putter.

And it's very much the right choice as he gets down to about six feet from what must be putt of about 120 feet and with 30 feet of break perhaps as well. Astonishing effort.

This is Hideki Matsuyama's 13th US Open start and he's only ever missed the cut once. When was that? 2016 at Oakmont.

He had made a solid start to his second round in 2025, but it looks like quickly unravelling as he slaloms his way down the par-five fourth.

Somehow he sinks a long-range bogey putt to limit the damage to just a bogey.

Adam Scott will be kicking himself after going long with his third from 130-odd yards, which left him with next to no chance of saving par.

Ludvig Aberg witnesses the carnage from afar and walks off with a par five.

Dodgy start this from Robert MacIntyre as he's bogeyed his opening two holes after a five on the 11th - caused by missing the fairway and then missing the green.

Getting close with chips around the green from this Oakmont rough is about as tough a test as it gets. Work to do for Bob now.

Rory McIlroy is in trouble again on the third as he booms into the right fairway bunker.

It's around 110 yards to the flag from here but his second thuds into the face of the sand trap and disappears into the thick stuff.

The five-time major champion has little to no control over his third from there and it zips through the back of the green.

A very short media conference from 2021 US Open champion Jon Rahm, who finished round two at four over par:

"I didn't play bad - I played quite good golf. I didn't make a putt. That was the main difference. I didn't see anything go in beside a seven-footer on seven. That's it. That's a very hard thing to deal with to try to shoot a score out here.

"Honestly, I'm too annoyed and too mad right now to think about any perspective. Very frustrated. Very few rounds of golf I played in my life where I think I hit good putts and they didn't sniff the hole, so it's frustrating."

JJ Spaun makes the most of one of the two par fives on the course, reaching the green in two and carding a birdie four to return to the top of the leaderboard on his own.

Justin Rose goes miles right off the tee on the second, so much so that he is dropping a yard or so past the cart path and well wide of the stand full of fans.

His second, well actually his third cannons something and flies back down the cart path where it is stopped accidentally by a guy on a scooter, who simply could not get in reverse quick enough.

The Englishman knocks his fifth, a putt from another post code into three feet. It'll be a double from there surely.

Meanwhile, Rory McIlroy clips on in two and will have a look at birdie from 10 feet but that's always straying right and ends up with the world number two taking a par.

Two holes played for Shane Lowry = bogey + double bogey. Making the cut seems a forlorn task from here and he still has 16 holes to play.

Xander Schauffele won two majors last year and his US Open record is incredible - he's struggled with injury in the first part of the year but he looks like he's getting back to his best.

And his best will easily be good enough to challenge for the title at Oakmont this week.

He's started today in the best possible fashion with consecutive birdies to get to level par for the tournament.

Bob MacIntyre starts with a bogey on the 10th after leaving himself with a slippery little devil of a putt down the hill for a par.

It's got a touch of left-to-right in it as well so he's rightly terrified of it whistling well past the hole, so just nurdles it at dead weight, but it just slides wide.

Pars all round for this group on the third.

All three had lengthy birdie chances and were not far away, to be honest, but they'll all have to settle for fours.

Up next is the par-five fourth, which is one of the better scoring opportunities on the golf course.
