Justin Thomas took to the practice range at Erin Hills before Saturday's third round of the U.S. Open sporting fluorescent pink slacks. Certainly, there is evidence to that effect: five scores of 65 or lower, including Thomas' 63 that tied a major championship record.

Thomas rocketed into contention on Saturday, carding a nine-under 63, the best round at a U.S. Open in relation to par that also equalled the lowest numerical score in any major. This unprecedented 9-under-par came here where the glaciers once receded and the cattle once grazed and the U.S. Open never turned up until now, with a card nearly as red as the Alabama Crimson Tide for whom Thomas once played. It's the first 63 at the U.S. Open since Vijay Singh in 2003 at Olympia Fields and the fifth overall in tournament history.

The Kentucky native became the youngest player to shoot 50 on the US PGA Tour during the first round of his Sony Open victory in January.

Koepka - like Jason Day, Danny Willett, Dustin Johnson, Henrik Stenson, Jimmy Walker and Sergio Garcia - is a bridesmaid no more.

"It was a good bogey though", joked Fleetwood, who regained his composure to hit a superb pitch from well below the putting surface. Nine players are within 4 shots of the lead - and we're wondering if they have what it takes to get the job done in one of the game's biggest tournaments.

However, neither Thomas and Fowler aren't the leader heading into Sunday's final round. If I wake up with the same feelings tomorrow I'm going to have a chance.

"Yeah, 12-under, I'd have about a ten-shot lead in most Opens", said Harman after shooting a 5-under 67 on Saturday.

"I'm looking forward to my shot at it, and I know it's not going to be an easy day".

Tommy Fleetwood is a 26 year-old Englishman who plays most his golf on the European Tour.

"(The wind is) going to blow and the scores could be a good deal higher tomorrow if the weather comes to what they're predicting", Harman said.

The leaders are set to face Erin Hills at its hardest today. 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. It's the scorecard of a remarkable wisp of a 24-year-old Kentuckian from the third round of the U.S. Open, and it's a fresh beacon of hope in the centuries-old struggle between humanity and golf.

"Yeah, I got a little frantic around the green", he admitted of the 18th-hole meltdown.

Thomas added to a year of low numbers.

Harman, who won his second PGA Tour title this year in the Wells Fargo Championship, said sleeping on the lead will be no problem.

"It's what I believe in myself", Stricker said. "As good as his college career has been, I think Scottie will have a better career as a professional".

After pars at 16 and 17, Fleetwood dropped into a second-place tie following a bogey on 18 when his fourth shot rolled off the back of the green.

"The consensus from anyone that I've talked to is they really like the golf course". Then comes Thomas and Brooks Koepka (68), who are one shot back.
