Super touch from Tommy Fleetwood as he was almost 40 feet back from the hole when he lined that up.

He's rolled it to two feet and collects his par. An immaculate card so far.

He's since dropped a shot, but Scottie Scheffler's birdie on 10 is worth a second look...

That's a tentative bogey for Scottie Scheffler. Spooked by Collin Morikawa going in the water he bailed out miles right, and his chip onto the green raced too far by and he couldn't rescue a par with the putter.

The pressure's just creeping up a notch.

It's gone south big time for Collin Morikawa, who plays a decent chip after his drop from the water, but then blasts a putt through the break and when he taps in the return it's for a double bogey.

Max Homa is in all sorts of bother here. With absolutely no hope of playing his ball from where it landed he has his driver out and is looking at a drop.

Byeong Hun An managed to get out from a similar position a little earlier but duffed straight into the sand and ended up with a double bogey five on the 12th.

Fair play to Tommy Fleetwood who has been really controlled all day.

He keeps giving himself chances and on the par-five 15th, he's got a long birdie putt to get to five under.

As things stand that would put him joint third!

Seems as though the only way to stop Scottie Scheffler now is if Meredith rings to say their baby is imminent...

All of a sudden all of Scottie Scheffler's competition appear to be imploding...

Max Homa heads straight through the 12th into the shrubbery. Ludvig Aberg is left but on the dance floor. He'll have a putt from another zip code, mind.

Collin Morikawa shouts in annoyance as soon as the ball leaves his club on 10, and that's because he's pulled it and that only means one thing on this hole - water.

Scottie Scheffler watches the splashdown and there's no way our Masters leader is following him in so he hangs his approach short and right for safety.

A first real loom of consternation comes across Ludvig Aberg's face as his bogey putt from 20 feet or so touches the left edge of the cup but doesn't disappear.

Max Homa saves his par and is now all alone in second in the chase to reel Scottie Scheffler in.

This 23-foot birdie attempt looks good for Bryson DeChambeau at 12.

It's on line and trundling along but then suddenly runs out of gas a foot short.

A couple more turns and he'd be at four under.

Not happening though.

A courageous try from Tommy Fleetwood to claw back another shot on the 14th.

His birdie putt from 20 feet is always hanging right and doesn't move the way he wants.

He'll stay at four under.

If Scottie Scheffler goes on to win the Masters, he may look back at his stunning shot on the 10th as a turning point.

A very big moment incoming for Ludvig Aberg here who is taking a drop.

The 24-year-old finds the dancefloor with his fourth but is facing a long putt back just to limit his losses to one stroke.

Max Homa, who set his second well away from the pond that did for Aberg's ball finds the green but can't sink a long birdie putt.

An update on Cameron Young who has botched the 13th.

A grisly double bogey puts him over par for the tournament.

He's well out of contention - and probably out of this live text coverage.

Is Amen Corner about to do for Ludvig Aberg?

Aberg strays well left with his approach and sees his ball bounce off the bump skirting the green and dunk itself into the pond.

The Swede has not dropped a shot on the 11th yet this week but has serious repair work to do here.

This must feel like an awfully long time ago for Collin Morikawa.

At seven, he holed this to tie for the lead.

Now he's four shots back.

Such a stunning iron shot had to be rewarded with a birdie, and Scottie Scheffler obliges by tickling his effort down the slope with just enough borrow on it to drop in the right half.

That's a two-shot lead now for the world number one who looks to be getting into a groove with three birdies in a row.

Went too early on Bryson DeChambeau!

I thought he'd made his birdie putt on 11 but it's dribbled wide.

Serious frustration for the American as he really needed that.

How to announce yourself at Augusta.

Does Ludvig Aberg realise just how good he is?
