Harman, Fleetwood and Koepka have posted scores of 67-70 in each of the first two rounds.
But only for a couple minutes.
Brian Harman stood on the podium with hands on hips, giving answers in the kind of matter-of-fact voice expected from someone used to the spotlight of a major championship. He shot 81 the next day in a blustery wind. There's just too much luck involved.
The U.S. Open was only his sixth start this year.
This is only his second U.S. Open, finishing 27th in 2015.
And the prime beneficiary was American Thomas, who catapulted up the leaderboard with a record-breaking nine-under-par 63.
What a day for Justin Thomas. Vijay Singh was the last player to accomplish the feat in 2003 at Olympia Fields. The U.S. Open is supposed to be the antithesis of that. Thomas' 9-under 63 was one better than Johnny Miller's 63 in the 1973 final round at Oakmont. He is at 11 under, two shots ahead of Charley Hoffman and Tommy Fleetwood. Or at your home course.
It didn't work all that well.
Day added a 75 to his first-round 79 which included two triple bogeys.
Rory McIlroy will miss the cut, but at least one of his US Open records is safe - 35 consecutive holes without a bogey to start a US Open.
Some of the world's top-ranked players and pre-tournament favorites will miss the cut. Here if you can hit it long and straight, it's a great advantage.
Fortunately for the Englishman, he also carded five straight birdies on the front nine and signed for a 1-under 71 that leaves him at minus-7 through 36 holes. All at seven under par at Erin Hills. Rickie Fowler accomplished the feat in the first round, and Hideki Matsuyama and Chez Reavie hit the number Thursday.
"Guess what?" he said to 4-year-old Dash.
Up to that point, Fleetwood pretty much couldn't find trouble if he tried.
Charley Hoffman is all by himself on top of the U.S. Open - for now.
Casey made a snowman - a triple-bogey 8 on the par-5 14th - and still broke par with a 71. So whatever happens I'll be doing my best and seeing how well I can finish.
A superb chip to three feet set up the birdie on the 597-yard first hole before he then demolished the short par-four second. And he's giving the fans something to cheer.

A message from The Queen on Her Majesty's Official Birthday. "Put to the test, the United Kingdom has been resolute in the face of adversity".
Rory McIlroy almost aced his final hole Friday, striping a 153-yard approach on No. 9 to a hot dog's length.
He shot a 69 to finish at 1 over for the tournament. But it will be a pleasure to go out on a Sunday trying to win a major.
Still, Stricker was struck by the players' power. He just has to listen to the crowd. He was coasting along Friday, playing par golf and hanging out at the top of the leaderboard.
Hoffman has opened his third round at Erin Hills with two birdies to move into a four-way tie for second at 6 under. She went from a three-shot lead to one shot behind, and eventually lost to So Yeon Ryu in the playoff. It took a hard turn to the right and rolled in. He grabbed his putter and pointed it out to his left just as the ball dropped into the cup.
Amateur Scottie Scheffler is playing with the poise of a veteran at the U.S. Open.
Leishman is in a share of 13th place, three shots off the pace.
"Showed up for the last six holes, anyway, " he said.
Still, to be fair to the USGA (and who doesn't want to do that?), Erin Hills played its toughest Saturday in part because of overnight rains that dumped.91 inches on the course, softening it and making it play even longer than its listed 7,818 yards.
But three costly bogeys on the back nine left Johnson needing to pick up strokes down the stretch which proved beyond him.
"I birdied the first two holes, but those were tap-ins".
Low scores were available.
After tying for 45th at the Memorial last month, Matsuyama arrived at Erin Hills on a downturn in a topsy-turvy season. Jordan Spieth was even par through 12 holes and going nowhere. "I have relatives and a lot of friends in this state alone".
Not bad for a guy who made the cut on the number. "Because the more you dissect it, the worse you're going to feel about yourself".
He's going to have to get it cleaned to wear it again this weekend. There were 18 rounds in the 60s on Saturday.
But that's not all that makes the possibilities so limitless Saturday.
In all, 23 players are within four shots of the lead.
Now consider that the largest 36-hole comeback in U.S. Open history was 11 shots by Lou Graham in 1975.
