But only for a couple minutes.
Of the four, Fleetwood - who was ranked 188th in the world rankings as recently as last August, but now up to 32nd - is the only one never to have won in the United States. It doesn't have much history, "but everybody had to start somewhere".
McIlroy, who has struggled through a nagging rib injury that has limited him to six tournaments this year, saw some positive signs in the second round after complaining about feeling rusty after his substandard opening 18 holes.
That was a 10-shot improvement on his second round and left the 26-year-old on eight under par as he seeks to turn his Ryder Cup heroics into individual success. It was the lowest third-round score in Open history.
"I think that's a testament to how good the golf course is and how well it's set up", Harman said.
What a day for Justin Thomas.
The 11-year-old course - the first in Kubly's childhood home state of Wisconsin to host the Open - is making its grand debut for scores of television viewers. Vijay Singh was the last player to accomplish the feat in 2003 at Olympia Fields.
As a point of fact, the U.S. Women's Open is not organized by the LPGA. "I'd love to have another one of those", Thomas said. He is at 11 under, two shots ahead of Charley Hoffman and Tommy Fleetwood. Billy Horschel was tied for the 36-hole lead at Merion. He missed the 15-footer. "Hit fairways, greens. but you don't have to off by a whole lot, kind of a fine line", he said of those dropped shots.
"I missed the cut, but I'm optimistic going forward".
Fleetwood was alongside Reed after a birdie on the first but Casey tumbled down the leaderboard after following an opening birdie of his own with a triple-bogey on the third.
Casey swung and missed from the tall fescue on No. 3, and then chipped out and it rolled all the way off the green on the other side.
Casey chopped his way to an 8 on the par-5 14th and shot 38 on the back nine.
ERIN, Wisconsin, June 16 Paul Casey overcame a stunning triple-bogey eight at the par-five 14th, his fifth hole, to lift himself into a share of the second-round lead at the U.S. Open on Friday.
The banner flying over Erin Hills is the work of a women's group called UltraViolet, which announced its intentions on Friday.
Hideki Matsuyama had quite a day at Erin Hills.
OK, this is his first U.S. Open.
Brooks Koepka started on No. 10 and made four birdies on his front nine to get to 9 under, moving into a tie with Fowler for the top spot.
But in the previous two U.S. Opens, Johnson added life to what is traditionally golf's toughest and often most drama-free major.
But it was his tie for fourth in the 2014 U.S. Open at Pinehurst No. 2 that enabled him to get a PGA Tour card.
Englishmen Paul Casey and Tommy Fleetwood and Americans Brian Harman and Brooks Koepka are sitting at seven-under, a shot ahead of Fowler, also of the USA, who had a one-over-par and is tied with compatriots J.B. Holmes and Jamie Lovemark. PGA Tour rookie Xander Schauffele didn't make a bogey at Erin Hills until his 27th hole, had his hiccup with a double bogey on the par-3 13th hole but still managed a 73. And he's giving the fans something to cheer.
Koepka had the lead until he turned a birdie chance into a bogey on the par-5 first hole after making the turn. He shot a 69 and was at 2-under 214. The top 18 players on the leaderboard going into the weekend have combined for zero majors.
