Rory McIlroy finds a clear spot behind the 10th green, but just flubs his chip shot that goes hardly anywhere - and he has a stern glare at the ground beneath him as he's not happy with something about the lie here.

He chips onto the green at the second attempt but now has a long putt just to make bogey.

Picked up a nice wee spot where I had a clear view of Scheffler's approach into nine and McIlroy's into 10.

Scheffler's ball stopped on the green only a couple of seconds before McIlroy tried his best from a sidehill lie.

It is admittedly flat out here, even with news of a rare Scheffler double filtering through.

Bryson DeChambeau has been talking to BBC Radio 5 Live's Andy Stevenson:

"I didn't play that much different on Thursday compared to today. I just didn't get a couple of breaks and it went south quickly.

"Hopefully I can be like Tom Watson and fall in love with links golf and embrace it in and give myself chances in the next couple of decades."

On Open leader Scottie Scheffler's performance: "It's very Tiger-like for sure. I wasn't playing during Tiger's timeframe, but I played with him a couple of times and you feel there's this difference in the air with him.

"I want to be paired with him a lot more because I want to feel and experience it and learn from it, because he's setting a benchmark at the moment that we all want to aspire to."

At times, it's felt like climbing Everest chasing Scottie Scheffler today.

He's recovered from that little slip-up - and now has to tackle Himalayas...

The last group both make their birdie putts on the ninth.

Li Haotong is now in a share of second place, while Scottie Scheffler's lead increases to five shots at the midway point of his final round.

You get a lot of jumpy lies on a links course, when the grass gets between club and ball and results in it flying far further than it would usually.

Rory McIlroy has got a monster one here and has air mailed the 10th green, going miles over the top and into the rough behind.

Beautifully done by Li Haotong, whose second shot from out of the rough catches a bank at the back of the green and rolls about six feet away for birdie.

Scottie Scheffler has a much more straightforward pitch and he's got five feet left for a three.

If Chris Gotterup has seen a leaderboard he'll know how close he now is to the lead, but he's wayward with an approach and has a stinker of a shot from off the 10th.

But he's played it wonderfully, getting creative and using the bank behind the flag to run it up and back down - before then making the putt for par.

That's brilliantly thought out from someone making their Open debut.

Now he's five behind he'll be thinking this is all to play for.

It's amazing how quickly it can change.

Really poor from Rory McIlroy with just a dink in from 70 yards but he left it miles short and had to settle for yet another par.

He should be looking at six feet from the flag from that range, but he's three times that far away and that four gets him no closer to Scottie Scheffler after his big mistake just behind.

Will it be normal service resumed for Scottie Scheffler after that double bogey at the eighth?

He's in the semi-rough off the ninth tee, but only just.

Meanwhile, Li Haotong's tee shot goes left and ends up close to a group of spectators, who crowd around it like they've never seen a golf ball before.

There was a big 'ooh' from the crowd after news of Scottie Scheffler's double bogey.

Rory McIlroy's eyes instantly flicked to the leaderboard.

Everyone’s got a little excited. It’s game on here.

There’s still a long way to go but at least it’s made it a bit more interesting and it’s nice to see a little chink in the armour.

I did not see this coming about 15 minutes ago. You very rarely see errors like that from Scottie Scheffler.

It's a double-bogey six for the world number one and, with Chris Gotterup making progress up ahead, Scheffler's lead is back to four shots.

Meanwhile, Li Haotong's long, uphill birdie putt comes up a couple of feet short and he'll tap in for par, keeping him in a share of third place.

Brilliant drive from Rory McIlroy on the ninth, smashing it 352 yards to leave just over 70 to the flag on this par four.

He really needs to get this one close...

It's a case of giddy-up Gotterup as the American rolls in a birdie on the ninth to break out of that tie and take solo possession of second place.

Thr Scottish Open champion last week turns in a three-under 33 to sit on 11 under - with Scottie Scheffler in a rare spot of bother just behind him.

Now then... Scottie Scheffler finds a bunker on the eighth and goes for the big shot out of it - his ball hits the lip of the sand trap and lands back by his feet.

He takes his medicine second time around and is in the middle of the fairway in three.

He'll probably hole out from there for par, the way he's playing.

The crowd have been enjoying Matt Fitzpatrick's style of reading putts.

He lies flat on his stomach and presses his knuckles into the turf. Not quite Camilo Villegas levels of athleticism, but still unorthodox.

"Let's see you do a push-up," a fan yells.

He didn't. He did make the putt though.

When Scottie Scheffler was one back on Thursday I mentioned that the Jaws music was looming as he came through the elements and challenges thrown his way.

I think you're going to need more than a bigger boat to stop Scottie the shark today.

In answer to Oliver Wilson at 16:06 BST - Scottie Scheffler has gained 10.5 strokes in putting during this tournament.

That's almost three more than Oliver Lindell, the man who is second on that list.
