Hovland will be massively disappointed. You can hear the crowd screaming for Rory to bring him home.

Rory McIlroy was three adrift of Cameron Smith at the start of play.

He now leads the Australian by five. Quite the turnaround.

Hovland goes up and over the slope with his putter from the front of the 14th green. It's another hugely impressive effort from distance and he'll have about 15 feet for a birdie.

McIlroy has 33 feet for his second eagle in five holes. Ooooh, the pace was good but it was always on the high side. It's good enough for a birdie though!

Can Hovland match him in four? No! It lips out on the left.

McIlroy leads on his own!

That was a very messy hole for Cam Smith. Unforced errors and terrible decision making.

Cameron Smith is hacking about in rough which resembles his mullet.

Long, thick and not entirely attractive. Similar colour too.

He knocks out onto the green, but has a long bogey putt to limit the damage.

Confidence is drained, never looks like going in and that'll be a double bogey.

Not much better for Cameron Young, either. He misses a par putt and drops back a shot.

It was like Johnson just lost control of his arms!

A bit of a sigh of relief as he salvages a bogey.

Just counting up all of DJ's shots on 14, and we think it's a bogey six for him, after being forced to bunt out of that nasty bunker in the opposite direction to the flag, before dribbling a pretty ordinary par putt well short.

It is though, after all that, just one shot gone which isn't actually a bad result after that wretched passage of golf.

Hovland, playing from the right fairway, gives what looks like a driving iron the full treatment but even that can't get the ball home in two.

He'll have plenty of green to work with, though, so it's not a bad leave.

McIlroy, from the fifth fairway, hammers a long iron towards the target. It lands just short but takes a lovely hop forward and rolls up close to pin high! An eagle opportunity awaits the 2014 champion.

It's all unravelling for Cameron Smith here.

He actually missed the gorse bush but ended up in a clump of heather.

Another chop out does not go as he envisaged and there is going to be at least one dropped shot here.

Count to 10, Cam...

Matt Fitzpatrick drops his head, cutting a dejected figure, as his par putt at the pesky 17th slides by.

Back to eight under.

Big trouble for Cameron Smith - that was a bad miscalculation from him to try and carry over a vast array of gorse bushes - and he duffed it.

In fact there is also a mis-hit from Cameron Young - both our final pairing are in trouble here.

Johnson has had an absolute shocker on 14, as he putts from the right edge of the green and sends it right across the dancefloor and off into a small pot bunker off the opposite side!

Awful mental error and quite frankly something one of us would do playing around here in tournament conditions - but you don't expect it from Dustin Johnson.

Oh no! Cameron Smith has a 'mare of a shot. No stance whatsoever.

The overnight leader drives left on the 13th and although his ball stops short of the bunker, he's going to have to stand in the sand to have a shot.

So, he's about three feet below his ball and reaching out with his iron.

Gorse bushes are lurking ahead, too. That's where he ends up after a duff.

Smith is fuming with himself.

One thing about Saturdays at the Open is as the final pairings progress down the course, swarms of people battle it out to try and follow them. Every time Rory McIlroy hits a drive you can see the masses scuttling along the rope. And why wouldn’t they, big finish coming up.

It's a three-putt from off the front of the 16th green for Kim Si-Woo and the youngest ever man to win The Players drops his first shot of the day and slips back to 10 under.

He'd just birdied 14 and 15 too to get right into the mix on 11 under but he's still there or thereabouts with two holes to play.

Putting is always going to be one of the strengths you need on this course, if you want to be The Open champion, and Hovland and McIlroy have been demonstrating that.

McIlroy sets up to unleash one down the 14th.

Ha! It's so far left that it actually scampers its way on to the fifth fairway.

The Wrong Fairway - the Wallace and Gromit flick we didn't know we needed.

Hovland holds a cut up against the breeze and watches as his ball scuttles on down the fairway - the right one.

Rain is starting to fall on the Old Course. That is all.

It has gone a little bit quiet around Smith and Young. It doesn't feel like they are the last pairing out because of the attention being given to McIlroy and Hovland

Smith has had a lot of chances but he has had nothing going in for him at all today.

Young judges it to perfection though, and he sits at one shot off the lead.
