Scottie Scheffler's approach is so close to the first hole that he doesn't even need to mark it before tapping in for birdie.

The type of moment that will pierce the balloon of hope of the chasing pack.

Li Haotong mops up from close range too and keeps Scheffler's lead at four.

Erm, we probably won't need this, but just in case.....

While I don't want to get hopes shooting too high, it's important we discuss the prospect of a play-off.

The R&A's preferred play-off in recent years is for four holes with the lowest aggregate score winning.

The layout at Royal Portrush makes that tricky, so, as was the case should we have needed one in 2019, it will be three holes. The first, 13th and 18th.

Regardless of who you think might be in one, hit those thumbs - up for we're definitely going to extra holes. Down for we don't need extra holes, Rory's got this wrapped up!

McIlroy can't quite replicate yesterday's opening-hole fireworks, but he'll take a stress-free par.

Good four for Fitzpatrick, too, after a nervy tee shot.

Like yesterday, it's a scorcher out here. The short sleeves are out and everyone's ready for a big day on the links.

Oh, a great approach from Li Haotong to the first - within about six feet of the pin.

And Scottie Scheffler - he's about a foot away! Lands it to the right of the green and the contours bring it back towards the hole.

Talk about a good start. That's incredible.

A welcome early birdie on the third for Russell Henley, who carded an excellent 65 yesterday.

It takes the American to seven under and right among the chasing pack.

Lovely touch from Matt Fitzpatrick with a chip from short of the first green - still can't get my head around his left hand below right chipping style but he really does make it work.

Rory McIlroy has acres to cover with his birdie putt after an overly aggressive approach from 178 yards - and although it's a great effort it's never going in.

We saw a few too many of those yesterday as the major improvement he needs to make for today is to stick his approach shots much, much closer to the flag.

I don’t think Li will be scared. He doesn’t lack confidence. He likes to be the centre of attention and it doesn’t get more central than this.

This is why we play the game - you want to be in these situations, you want to test yourself and see what you’re capable of.

This is his time, he’s come back from almost losing his card and he’s now at the prime slot on Sunday at The Open.

He will be wanting to take that trophy home.

Li Haotong steps up first for his opening drive and he's bang in the middle of the fairway.

Now the leader. Scottie Scheffler gets a great reception from those watching around the first tee and the world number one goes slightly left - but he gets a favourable kick which means his ball stays in the semi-rough and doesn't drift into the longer stuff.

Here's the hole they're tackling...

A nice bunker escape from Harris English finds the green and enables him to then save par, which is matched by Chris Gotterup as they both remain on eight under.

This is a remarkable effort from Gotterup, who only qualified for Portrush by winning the Scottish Open last Sunday and with this not only his Open debut but also his first visit to Northern Ireland.

There are a number of areas we could have picked for this.

His putter has been red hot.

He's made the joint fewest bogeys in the field along with Li Haotong (just three).

But actually it's his destruction of the par threes that really stands out.

So far, he's -6 for them this week - and remember one of them is the infamous Calamity Corner at 16.

That's twice as good as the second best.

We'll also have video highlights of some of the key moments as the day progresses.

Disappointment for Tyrrell Hatton, who gives back that birdie from the first on the very next hole.

After finding a bunker off the tee and not being able to advance it too far from there, Hatton gave himself a chance of a five-footer for par - but it didn't drop.

The Englishman back to eight under.

Take a look at the best of Scottie Scheffler's clinical round on Saturday that has given him one hand on the Claret Jug...

The next best is Tyrrell Hatton with 43 greens in regulation and then Rory McIlroy hitting 42.

If Li Haotong continues to knock it onto the putting surface and give himself chances, he'll stay in with a shout.

By contrast, Scottie Scheffler has only hit 41 greens so far this week.

An eventful day for Sergio Garcia who shot a 68 despite snapping his driver in anger on the second tee after finding the left rough.

Ironically he went on to make a birdie on that hole, and then four more despite not having a big dog available for the next 16 holes.

That's some effort.

Scottie Scheffler, decked out in a blue polo shirt and cream trousers, has completed his final preparations on the range and has about five more minutes to wait before he begins his final round.

With the world's top two players, Rory McIlroy and Scottie Scheffler, in the final two groups, Li Haotong might escape a lot of the glare of many following today's final round.

He's a four-time winner on the DP World Tour and he has Open pedigree.

On debut in 2017, Li shot 63 in the final round to finish third at Royal Birkdale.

Familiar names dot the leaderboard but Li Haotong from China, who most recently made the cut at The Open in 2018, is Scottie Scheffler's nearest challenger.

His is an unlikely story as he tries to become the first Chinese player to win a men's major.

It's been a rollercoaster career for Li. Third on Open debut in 2017, he almost walked away from golf in 2021 after injuries and a loss of form.

Now, he's heading out in the final group with the world number one.

Li has even been dubbed the "most handsome man in China" in a joke with his club manufacturer - and Phil Mickelson even got involved.

If Rory can get off to a good start, this place will be electric.

If he doesn't get off to a fast start, there might be a bit of a dampening to the atmosphere.

Rory McIlroy finds the first fairway with the driving iron, as has been the play all week, and it's accompanied with the sort of hefty roar you've now come to expect this week at Royal Portrush.

Matt Fitzpatrick's tee shot is accompanied with almost absolute silence as his ball fizzes out to the left and finds the rough.

"Rory, Rory, Rory" goes the crowd as McIlroy marches off...incredible scenes again.
