The roar we heard meanwhile comes from the 16th, where Rahm makes a two to get to 10-under. Still, McGinley insists these dudes can win from there.

Thomas then aces it! Unreal. Can't putt? Don't putt. Shame it came after a five and a six.

1745: It's a double for Molinari and the lead is now 11-under.

I know nobody cares but Ortiz is about to birdie the eighth. Sigh. He's a birdie away from somehow finishing as the top amateur. Or a bogey from finishing second.

1743: Another twist at 12, potentially, as Woods comes up six feet short. If he misses and Molinari makes... they halve the hole.

1741: Fowler has six feet on 14 to get to nine-under. He'd need that, then an eagle, then another couple. Schauffele now on 13, this for at least a share of the lead... and it's always high. Birdie though and 11-under.

1740: Day misses a good chance and I believe his hopes die there, too. Sorry to be negative. Molinari has 10 feet or so for bogey, Finau will have four or five. Great shot from big Tony.

1737: McGinley telling us Day and Bubba can win now but I would stress that 13 is a pitch-n-putt hole today. Schauffee will have 20 feet for eagle - it just isn't a par-five today.

Bubba with a creative par at 16 and to have any chance he'd need to finish 3-3. I'm sorry, it's a nonsense to make out as though he's a huge runner here. He isn't.

1735: Woods finds the green a long way left of the flag. Sensible play, over the bunker, knowing that short would be spared.

Finau also comes up short and he looks to have found water, too.

1734: WOW! Molinari also wet on 12. This is staggering.

1733: My Request-A-Bet was Hovland to make the cut (tick emoji while we're at it), Bubba top left-hander which is just about weighed in, 10-under or better winning score and... Scott top 20. He's 18th. Ties paid in full. Could be close, not that I imagine anyone backed the 11/1 chance.

1731: Doubles for Koepka and Poulter, the latter falling six adrift and that's that. Koepka could rescue it but needs to get both shots back in one go at 13.

1729: Tiger gets both speed and line wrong at 11. The silver cloud is that he won't have to play first at 12 but he needs to mop this up for par from three feet.

At 12, Koepka misses and that's a double. Nobody is safe at Augusta. Woods makes par.

1726: Poulter and Koepka will have eight feet apiece for bogey at the 12th. Ahead at 15, Day birdies and Bubba eagles - they both get to 10-under.

1724: Ideal. He's 35 feet right of the flag.

I can't believe this - Poulter also wet on 12.

1723: Huge moment coming for Tiger. He has a shot, but if he attacks the pin that means a draw, and if he over-cooks it that means water. Front right of the green would be ideal. This isn't the time to try and do something - even if you're called Tiger Woods.

1721: Brave and excellent from Francesco as he leaves 30 feet for birdie at the 11th.

1719: Thomas three-putts and that takes him from a full place to no place as things stand. He's such a good putter when at his best but he just cannot crack these greens. First bogey since Friday and all of them have been clumsy.

Big moment on 12 meanwhile as Koepka hits it in the water. That could be his Masters dream over for the year.

To nine, Hovland... and he three-putts. Bogey. One-shot lead. It's a cruel game, this one.

1716: Back on the front-nine Hao-tong Li is six-under for the day and has a brilliant round going.

Back to the action and Woods is way right, just like yesterday. Molinari is only a little right and may be worse off for a smaller miss.

1715: Heard a roar. Could it be Thomas from 20 feet on 14? Or has Cantlay pitched in on 13? It's not Cantlay, who goes through the green with his third.

Poulter now for par... misses low. Tame effort.

Oh and it wasn't JT. He hits a 20-foot putt 27 feet and is no working hard for par.

1713: A massive few minutes for the leader as Finau also misses. At 11, Poulter has 10 feet or more for his par as Molinari tidies up from three or four feet to lead by two.

Koepka will have five feet for his par at 11 as Schauffele just misses a good chance at 12. That tee-shot awaits Molinari soon but boy it's calm right now and playing as easy as it ever does.

1711: Woods leaves his par putt short. Astonishing. At the ninth, 33 feet down the hill for Hovland - that's for birdie and five-under. Two putts will do.

1710: A little surprised to see Molinari take a free drop rather than stand on a drainage cover, simply because he looked to have a great lie and now it's sitting down a bit.

Hard to tell from here, obviously, and it's a sensational shot which almost goes in and stops no more than three feet away.

1709: Cantlay basically shanks his second at 13, a lay-up. It's no disaster but his angle is not going to be good now.

I pause to thank Mark for two emails. Sadly, both had bad words in that I can't publish, as Schauffele leaves himself 15 feet for birdie at 12.

He's there, lurking, and is a candidate to make an eagle and get involved at the top.

Brilliant from Finau and he's inside six feet for par.

1707: Woods looking at bogey as he goes around 20 feet deep at the 10th. Could be that all three players drop a shot as Koepka fires his approach to 40 feet at the 11th.

1705: Opening for Molinari as Finau misses left on 10, Rory '11 territory, and Woods chips out. But then Molinari misses left himself and he's short-sided, albeit sitting up. He'll try to flop that close and I'd say will likely go 10 feet long.

One of those tricky runs as Poulter has to punch down the 11th fairway and leave a wedge in. Woods next from around 150 with his third...

1703: Schauffele drops one in from distance for a birdie at the 11th and is within three alongside Cantlay and Poulter, both in pine straw at 13 and 11 respectively.

Molinari is down the middle on 10 and he's a , who make Woods 4/1 and Koepka 9/2. Surprised to see him quite so short and the 18/1 Schauffele may appeal to some, likewise 10/1 Finau.

If you really do believe in Tiger, he's . The former is a definite chance if he finds the fairway.

1659: Koepka knows just how important that par save is at the 10th and he remains two back as Woods flares one out to the right.

1656: Brilliant from Finau as he drops it in the right side. He's out in 36, level for the day, and that's still within two as Molinari also makes a sweaty four.

1655: Molinari is heavy-handed and goes eight feet past the hole on nine. He'll putt for par after Finau, who is some 15 feet away after finding the bunker.

More importantly, Ortiz bogey at five and Hovland has two in hand.

1654: Augusta would've exploded had Tiger's ball turned half an inch left and rotated once more. What a par that is on nine as he lags it hole-side using all those contours he knows so well.

JT did hit his drive over the corner on 13 and has 22 feet for eagle. Pop that in, birdie 14, eagle 15, birdie 16 and he's 14-under. Birdie 17 for 15-under, par the last and we'll see. Right?

1652: Increasingly I think I'd like Poulter to win. Don't hate me. He has 20 feet for birdie at the 10th.

Oosthuizen keeps his place hopes alive with a birdie at the 11th the awkward git. Why can't he do the easy things better?

1650: If the tracker is right, Thomas has 131 yards in to the par-five 13th having cut off more of the corner than you'll likely ever see. Not totally convinced but it looks a good spot from which to create an eagle chance I say.

Ahead on the green, Day has one of those eagle chances but it just slides by.

1648: As I say that Woods appears to slip and pulls his approach to the ninth. It goes right to the back edge and leaves 45 feet or more straight down the hill. Tricky.

Molinari has an opening, then, and plays over the flag to around 35 feet. Not his best.

1645: As we approach the turn, whatever happens, it's good to have him back, in red, in with a chance.
