Right everyone, that's your lot for tonight as we'll leave you to stew over Wyndham Clark's six-shot lead at the US Open overnight - not as much as he'll be stewing on it though.

Clark really should be home and dry from here but Shinnecock Hills can strike at any moment, and it's bound to be the toughest it's been all week tomorrow.

He'll also be playing alongside Scottie Scheffler, and if the world number one can get off to a fast start then who knows what could happen - we could end Sunday with a seventh and newest member of the Grand Slam club.

What we do know is that in the US Open there's never any plain sailing, so make sure you join us at 18:30 tomorrow to see what twists and turns Clark will have to navigate if he's to become US Open champion again.

Twenty-one players have had a lead of six shots or more entering the final round of a major since the Masters started in 1934. The only one who didn't win? Greg Norman.

He memorably collapsed at the 1996 Masters and lost to Nick Faldo by five.

Wyndham Clark will know all about that and will be focused on avoiding the same sort of collapse - but that's the thing about golf, Clark will have all night and most of the day tomorrow to think about this lead, and crucially think about what it would be like to lose it.

So the job is not done yet.

Thirty-nine players have had at least a five-shot lead entering the final round of a major championship, with 33 going on to win.

The last player to fail to convert such a lead was Jean van de Velde at the 1999 Open Championship at Carnoustie. The Frenchman had a five-shot lead entering the final round but lost in a three-way play-off as Paul Lawrie won.

Thankfully for Wyndham Clark, there's no Barry Burn at Shinnecock.

Wyndham Clark strolls off the course at Shinnecock Hills in a Long Island sunset and that could be exactly what he does tomorrow - he may already be too far ahead for anybody to stop him walking off into the sunset with a second US Open title.

With a six-shot lead Sunday really is all about him - Shinnecock will be set up a lot tougher tomorrow and he's so far ahead that it's almost impossible somebody could come flying out of the pack, needing to shoot at least seven under to win if Clark can just shoot par.

Even Scottie Scheffler will be hard pushed to do that, so the chasing pack only really stand a chance if Clark comes back to them with a few bad holes. He looked pretty solid today though.

I think there are six still in this: Wyndham Clark, Scottie Scheffler, Xander Schauffele, Matt Fitzpatrick, Tommy Fleetwood and Collin Morikawa.

Even though they are so many shots off the lead – Fleetwood and Morikawa are nine shots back - we know majors can be won from that far back if they haven’t got that many players to overtake.

On this course, with the wind blowing, and they’ll put the barest minimum of water on the greens because they will want it as hard as possible.

If you get into a bad run, it can go away from you and it opens the door for others.

That bogey at the last stops Wyndham Clark from joining this list of the biggest 54-hole major championship leads. No surprise that Tiger's the only man to feature more than once:

• 10 - Henry Cotton, 1934 Open Championship
• 10 - Tiger Woods, 2000 US Open
• 9 - Tiger Woods, 1997 Masters
• 8 - Raymond Floyd, 1976 Masters
• 8 - Rory McIlroy, 2011 US Open
• 7 - Harry Vardon, 1903 Open Championship
• 7 - Jim Barnes, 1921 US Open
• 7 - Tony Lema, 1964 Open Championship
• 7 - Seve Ballesteros, 1980 Masters
• 7 - Brooks Koepka, 2019 US PGA Championship

There were some dodgy tee shots from Wyndham Clark as he hit nine of 14 fairways, and even worse iron shots at times as he missed nine of 18 greens, but his short game was immaculate.

He ranked fourth in the field today around the greens and also fourth in putting - although given the circumstances and his position then I don't think anybody did better on the greens today than our leader.

He made eight out of 10 putts between four and 15 feet and with so many crucial par saves he really leaned on his flat stick to keep his round going and keep his lead growing.

If that putter's hot tomorrow then nobody else will stand a chance.

Wyndham Clark's worst putt of the day comes on the final hole with a blatant push right from just four feet to slip one back to seven under for the tournament.

But that still means he'll go into the final round of the US Open with a six-shot lead over the chasing pack - although leading that pack will be world number one Scottie Scheffler, who will play alongside Clark in tomorrow's final group.

It was a bad day at the office for Matt Fitzpatrick who shot a four-over 74 to drop back to one over par.

That's unlucky. Sam Stevens' birdie putt at the last just slips by on the right and he taps in for a par and a third-round 72.

He's hung around admirably today and this is some performance from a man who was playing mini-tours a few years ago.

Xander Schauffele can't get his birdie putt to drop either and he tidies up for a par. That's a 73 for the two-time major winner which isn't to be sniffed at considering he had two double bogeys on the back nine.

An excellent par for Wyndham Clark given that wayward tee shot.

Played the rules beautifully and off he goes to the 18th hole on Saturday at the US Open with a seven-shot lead.

Wyndham Clark gets a cut on his arm for his troubles but he's not complaining after that drop - as he plays another nice chip and rolls in the putt for another par save.

One more hole to go before he can finish up and go start composing his acceptance speech.

Xander Schauffele clips a dead-eyed wedge into the final green and he'll have 17 feet for a closing birdie and to finish one under.

Sam Stevens goes slightly long and is looking at a 20-footer down the hill.

It's hard not to notice how Shinnecock Hills has emptied. It looks deserted out there.

Wyndham Clark has not done anything incorrect there. He was given relief from the obstruction and he took it.

If that TV camera wasn't there, he's hit the ball into knee-high rough. But now he's been able to put the ball where it's a routine shot.

Awful shot on 17 from Wyndham Clark off the tee, with a huge pull to the left and into the fescue - but his ball dopped right by a camera stand so he gets a drop away from danger.

And he manages to drop the ball perfectly to roll it back into the camera stand so he can now place the ball just as he likes it - so from deep in the fescue he's now got a clean lie to chip from.

Wyndham Clark currently leads the US Open by seven shots - which if it holds would match Jim Barnes in 1921 for the third biggest 54-hole lead in tournament history.

Only Rory McIlroy (8) in 2011 and Tiger Woods in 2000 (10) enjoyed bigger leads than this heading into the final round of the US Open.

Nice judgement from Tom Kim, 60 feet across the 18th green.

He leaves himself three feet to make par and stay in the red before the final day. In it goes - well played.

Collin Morikawa closes out with a par too. He's one over for the tournament.

I don’t want to be Mr Misery but Wyndham Clark has bent down with his pitchmark repairer and in that four feet, he has effectively turned turf up in four different ways on his line and tapped it down with his putter to basically flatten out its path. It’s almost like making a trough to the hole.

I don’t think that is using the spirit of the rule that allows you to tap down spike marks. He's mitigating against the unevenness of the growth of the grass - but that's the surface you're playing on.

I just don't think that is right.
