Two others with Cowboys connections missed the cut of 1-over 145: Peter Uihlein (2-over ) and Alex Noren (5 over).
McIlroy was never in the short grass from the 11th hole to the end on Thursday when he opened with a career-worst 78, and he didn't do almost enough in the second round until it was far too late. "I've got to keep the confidence going, keep the momentum and see if we can have a good weekend and have a chance on Sunday".
Yet Johnson was forced to bide his time for the next six holes, unable to convert the few birdie chances that came his way.
Fowler only had a one-shot lead over Paul Casey, who started eagle-birdie, and Xander Schauffele, a rookie on the PGA Tour who is playing his first major championship. This is the first time in major championship history that the top-three ranked players have failed to make the cut.
Jason Day was walking away from Erin Hills with his wife and son when he managed to find one positive about this U.S. Open. He missed the cut at last year's PGA and withdrew from this year's Masters after falling down a staircase. "But I think at the end of the day, it's competitive rounds and get the card in my hand".
"But I'm confident that I am prepared for whatever happens", he added, "whether something bad happens or something good happens - I'll just rely on that confidence". "I got in a hazard on one".
"As good as I got", he told Spieth, smiling as he walked with him down the fairway. Even though he hasn't won since THE PLAYERS Championship in 2016, he had been playing better of late, finishing second late last month at the AT&T Byron Nelson.
"I don't know", Thomas said when asked what he'd say to Miller, "but I'll be pretty happy". "I think it's going to produce a really great champion".
Thomas drained a putt on No. 5 which he literally started it in the wrong direction, and that, he said, wasn't even his best shot of the day.More news: The Moto E4 and E4 Plus now official
"It doesn't need to be too much of a change for this golf course to play pretty hard", he said.
However, heavy overnight rain dumped an inch of water on the course and that undoubtedly helped low scoring with players able to take advantage of receptive greens and attack the holes.
McIlroy said he has more work to do with the new putter he put in his bag (TaylorMade Spider) in order to raise his comfort level. He'll play Travelers, then head overseas to play the Irish Open, Scottish Open and British Open.
Thomas says "I had no idea in terms of 9 under being the best in the U.S. Open".
The last six majors have been taken by first-time winners.
Casey is not the only Englishman atop the leaderboard as he is joined by Tommy Fleetwood, who had an excellent round of 70, and is a group of four all at the top of the leaderboard going into round 3.
Right behind the leaders Friday was a trio of players that included Rickie Fowler, who went 28 holes before making his first bogey and then went three holes without making a par.
