A three-putt bogey from Harman on the 13th left clubhouse leader Matsuyama as Koepka's nearest challenger, but the American promptly got up and down from a bunker on the 14th and holed from 12 feet for another birdie on the next. And they plenty of company.
"I think I'll be more comfortable playing in the big events, and help me play better the next time", he said.
And after Haotong Li made a small piece of history Friday by surviving the halfway cut at the U.S. Open, he closed out a frustrating third round with a quadruple-bogey at the par-5 18th on Saturday. Instead of the overly cautious approach that normally prevails at most U.S. Opens, anyone thinking about holding the trophy will need to compile a barrage of birdies to have any chance.
By the end of the day, that wasn't even the most shocking number.
Canada's Adam Hadwin struggled in round three, shooting a three-over 75 to fall to one-over par for the week.
Jordan Spieth hit probably one of the best tee shots he has made all weekend at the U.S. Open.
No one took advantage like Fowler.
Harman birdied his last three holes to defeat Fowler on the 18th hole, and send the Bulldogs past Oklahoma State and to the semifinals.
"Really haven't had much U.S. Open pressure considering how I teed off at 10:49, and the leaders might be through 4", said Reed of his 65.
While Fowler still has ground to make up, he was pleased with a strong finish that saw him pick up strokes with three birdies on the 14th, 15th and 16th.
In the 116 previous U.S. Opens, only six players had ever reached 10-under par or better, never in the same tournament. "But I can't do that yet because I haven't figured out the other part".
"I still have a chance if I can score well (on the final day Sunday)".
Day and McIlroy, just to name a few, might not make it that far.
So yeah, outside of Fowler, we're left with a lack of star power, and the top of the leaderboard is completely devoid of anyone who's actually won a major.
Does it matter that Spieth is 4-over?
The putt ran past the hole and settled at the bottom of a collection area 70 feet away. "The scoring was so good this morning". "I think the biggest thing is the trousers I've been wearing throughout the past couple of years, they're the kind of material that if it rains, they repel water, as well".
It appears that Erin Hills, a first-time venue, has a lower threshold than the normal Open course. He was in California for his daughter's high school graduation, hopeful for enough of a weather delay to jet across the country to Wisconsin.
Not even the wind could stop the onslaught of low scores at Erin Hills.
There were a lot of low scores Saturday. The pilot, the only one aboard the blimp operated by Florida-based AirSign, was being treated for injuries. "I've just got to keep going".
"I'd love to have another one of those".
England's Fleetwood had led until the final hole, when only his third bogey of the week meant he relinquished the lead to 30-year-old Harman, leaving himself tied with Koepka and Thomas.
"It's not easy by any means, it's the U.S. Open", he said. One might expect a little more excitement - unless one is his caddie, James Johnson.
"I've got a good plan for this course". Despite dropping out of a share of the lead, Fleetwood will take the same mindset into today's final round as he remains in contention of a major championship that he said would be life-changing.
