"Yeah, yeah, I know".

American Justin Thomas equalled the lowest score in major championship history in stunning fashion to surge into contention for the US Open at Erin Hills. So far 31 rounds of 63 have been recorded in a major by 29 different players (including Greg Norman at Augusta National), yet no one has gone below that. He made an 18-foot curler on the long par-4 fifth hole, rolling the ball up through the fringe to find the right angle to the hole. On the 18th hole, he had an eagle putt for a nine-under-par 63, and all Thomas could think about was dinner.

"It doesn't matter how long, how whatever the course is", Thomas said about the longest course in major championship history. "Plenty of emotions. This is where I've always wanted to be", Harman said.

What he doesn't have to show for it is the lead.

Morgan was at 9-under 135 after two rounds and became the first player to reach 10-under par in the U.S. Open with a 30-foot birdie putt on the third hole of the third round. But Reed is in the mix heading into the final round, just four shots back of Harman at 8 under.

Spieth is well off the lead of 12 under held by Brian Harman.

Rickie Fowler is at minus-10, just two back. No easy task. The recent victor of the Wells Fargo Championship is clearly in the form of his 30-year old life. Five players already have carded seven under or better this week, another US Open record, with Patrick Reed also managing it today. At 6 under are J.B. Holmes, Hideki Matsuyama and Bernd Wiesberger (69). I'm not sure when it's going to sink in or when I'm going to realise what I did.

Even more comforting is this video of Jack Nicklaus responding to Miller criticizing one of his greens.

A lack of wind at Erin Hills, combined with greens softened by plentiful rain, has led to unusually low scoring throughout the week in Wisconsin. It was his only bogey of the day to go with five birdies. It was definitely conducive for good scores today. "When you give us soft greens and not much wind, you know there are going to be some good scores". "My game has felt pretty good all week and it was just one of those (days) - it was just trying to take advantage of the opportunities I had". And then Morgan came undone.

"Fun, I know that", Thomas said, and he said this at a U.S. Open, an event which, he said nearly poetically, "is known for making you kind of hate yourself and hate golf". "I'm looking forward to my shot at it. But I know I'm going to be nervous, but it's a good nervous".

"When he's gotten out of position, he's done a really good job of getting back in position", Harman's caddie, Scott Tway, said. And it will play a lot tougher.

The 24-year-old Louisville native is not new to success. She doesn't care if I'm leading the U.S. Open or not. "So I could feel a little bit again (on 18), but I just wanted to calm myself and just try to relax over that putt". "Sleeping won't be a problem".

It's a 54-hole leader board of rich potential.

"We're breaking down all kinds of barriers", Harman quipped.

"It's hard to stay patient, but I was proud of the way I did that". I got off to a pretty good start, which I really haven't done yet, so that was nice. He failed to get up-and-down from behind the 17th green, and then he three-putted from 40 feet on the final hole to finish at 8-under 272.
