A lag putt for Thriston Lawrence leaks wide of the hole and leaves four feet coming back to save par.

Nerveless - he's safely in.

Billy Horschel joins him. Onto the 12th.

If Rose and Schauffele can get a couple of shots ahead and as we know 17 and 18 are not easy holes, so that would give Lawrence an awful lot to think about for those two holes.

It's our job to do some research so we've looked into Thriston Lawrence and found this remarkable little note on the DP World Tour website.

"Such is Lawrence's passion for fishing, he created a dedicated Instagram account called golfergonefishing."

So we make no apologies in saying Lawrence is hoping to 'reel in the big one' today at Troon. And there's plenty more fishy puns to come too...

Russell Henley with a tough birdie putt at the 11th but it just teases past the hole. Another par for the American who just cannot crack it on the greens today.

Playing partner Sam Burns bogeyed the 10th but is able to save par this time round.

There are great shots and then there are "great golf shots" and Xander Schauffele just pulled off the latter when he dug his ball out of the rough and got it to chase all the way up onto the green.

Justin Rose had 190 yards from the fairway but he's pushed it right and although he misses the bunker his ball's rolled down into a nasty little dell. Trouble ahead.

The swollen galleries following Justin Rose and Xander Schauffele tell you this is where the action is, even if there are two groups behind them on the course.

A pair of short iron shots thunder into the 11th green as both Thriston Lawrence and Billy Horschel take aim.

They'll both trundle up there and eye up lengthy birdie putts.

It’s really calm here so in terms of conditions that’s nice for Thriston Lawrence.

It’s about pressure and staying in the moment and not thinking too much about what he might be about to go on and achieve.

Hideous tee shot from Scottie Scheffler as he crunches wide right at the 13th and into the middle of a Scottish jungle.

An envious look to the right would show him Dan Brown's ball sitting pretty on the fairway.

We're on the back nine on Sunday at The Open - is it a three-horse race for the Claret Jug now? Or can any bolters from slightly further back mount a late challenge?

Here's the top of the leaderboard:

-7 Thriston Lawrence (10)

-6 Justin Rose (11), Xander Schauffele (11)

-4 Russell Henley (10), Billy Horschel (10)

-3 Shane Lowry (13)

Let's see how Thriston Lawrence gets on with the most menacing tee shot on the course.

A swooping draw from the South African clears the unforgiving gorse bushes down the right, takes out the railway line and trundles onto the fairway.

Dead straight from Billy Horschel and he's also safely away.

Xander Schauffele makes no mistake as expected to tap in his birdie and join Justin Rose on six under - just a shot off the lead.

Rose remains on six under after salvaging his par from six feet - with a huge puff of the cheeks after a deep breath showing that he knew that was a big one.

Having followed Thriston Lawrence for a few yesterday and again at the start of his final round today, the big fella has never looked particularly agitated by the position he finds himself in.

Playing the Sunday back nine of a major is another thing entirely though.

In Scottie Scheffler's defence, he's still got the delightful touch around the greens as he skips it in close to make sure he takes away a par.

Six holes left for the world number one to haul himself back into contention.

Jon Rahm ends the tournament at one under par, in what has been by far his best showing at a major this year.

Hugely unlikely he'll be winning with that score, but it should be enough for another top-10 finish at The Open.

So unlike Scottie Scheffler at the 12th as he’s short of the green despite being in the middle of the fairway.

This is where it went wrong for him at nine and there’s no sign of a charge at the moment.

We've just mentioned Xander Schauffele's driving, but his iron play is his great strength, as he shows us with a laser from 173 yards that bounds up the green and threatens to go in before pulling up just a couple of feet or so short.

Justin Rose, meanwhile, is just short of the green and then a bit sloppy with his putt that whistles by and leaves work to do.

Wikipedia tells me Xander Schauffele is 5ft 8in tall so the way he whacks his driver he must be approaching pocket rocket status, as he can give it a biff alright.

He's smacked it 319 yards on the tough 11th and at that angle it's kind of a bit into the wind as well. Schauffele ranks 11th in driving on the PGA Tour and 37th in driving distance - so sneaky long is very apt.

Just a couple of drivers downwind from the course hosting the Open is something a little more suited to my skillset near Troon town centre.

Just £2 for 18 holes, which I'm guessing is a little cheaper than the Royal Troon green fees.

Still think I'd struggle to break 71 in these conditions, though.

Maybe save it until tomorrow, Ben. You don't want to miss any of this enthralling action...

We've seen Scottie Scheffler's challenge unravel - is it Billy Horschel's turn?

Out of the rough but needing 19 feet to save par, he can't convert. Suddenly, he's three shots back.

Lovely judgement from Thriston Lawrence as he two-putts smoothly from 50 feet.
