I've never seen Scottie Scheffler lose his composure as much as he has today. He's thrown his club at his bag. And now he's cleaning his own club as if to punish himself.

I think he's so frustrated with himself after getting back into contention and then bogeying 16 and 17 and now airmailing the 18th green from 133 yards.

WIll Zalatoris ends up with a dreaded eight on his card at the 14th thanks to a comedy of errors including that top, finding a bunker and a missed four footer which all costs him four shots.

That's a disaster on a normal course on a normal day - around Sawgrass today that's massive and has seen him drop out of contention.

Talk about baring its teeth.

Back-to-back bogeys for Tommy Fleetwood as his seven-foot par putt stays up.

He's seven shots off the lead now.

The 12th hole is risk and reward and I guess it's that time of the round for Akshay Bhatia.

He blasts his drive down and it bounces onto the green but then it continues to race. And race.

There's a slope there , his ball catches it and on it continues, down and down into the water.

Rory McIlroy is another player being frustrated by Sawgrass today as he drops a shot on the short par-four 12th that really should be a birdie hole.

He goes for the green but sprays it wide right, still just 50 yards or so left, but he fluffs one chip and can only get to about 15 feet with his third shot, before two-putting for bogey.

JJ Spaun shows him how it's done by finding the fairway and then hitting a wedge to six feet for a three and a two-shot lead.

Superb mentality from Alex Smalley as he saves par at the 13th.

He overhit his long putt from 45 feet and needing to sink from 18 feet to escape unscathed.

And he drilled it. He stays in touch.

As for playing partner Collin Morikawa, he's four over for his day and drifting ever further off the lead.

There's another ball in the water at 17 - but not in the conventional way as Scottie Scheffler lashes his ball into the water in furious anger after he three-putts for a bogey.

The world number one is running hot here, and not in his golf but in his temperament which is usually so cool and calm.

Will Zalatoris is fuming with his drive on 14 as he fires it out to the right in the rough on a mound - and he'll be even more angry with his second shot, as he tries to give it a big whack but only manages to top it a few yards down the hole.

Problems here.

Seven under par is where we find overnight leader Min Woo Lee but that number could get worse at 11 as the water claims his tee shot.

It's been a brutal round three for the Australian who is already four over for his day and tramping down the fairway.

Scottie Scheffler only drops a shot in the end, which is a result considering he was playing army golf all the way up there - going right-left-right before eventually finding the green.

He's not a happy bunny either with plenty of chuntering going on about the wind...

Urgh that's a frustrating one for Tommy Fleetwood as he bogeys 14 following an errant tee shot.

He's so close to saving par from distance as well but his ball is just off line.

He slips back to seven under.

Lucas Glover misses the green at the par-three 13th but it doesn;t matter as the former US Open champion goes and chips it in for birdie to go into joint second.

Wonderful shot.

In more breaking news... Matt Fitzpatrick and Billy Foster have parted ways, reports the Guardian's Ewan Murray.

Foster was on the bag when Fitzy won his US Open in 2022.

After burning the edge of the hole with a birdie putt on 15, Scottie Scheffler is having a bit of a mare on the 16th and looking a littler bit like your everyday hacker.

As the world number one has an ill-advised swipe out of the pine straw with his second shot, possibly going for the green but only managing to bunt it forward into some deep rough.

Then it's a chop out back across the fairway and into the rough short of the left bunker. Astonishingly scrappy.

It's nice to report a calm hole from the final grouping of Min Woo Lee and Akshay Bhatia.

They've pocketed pars at the 10th. Move on.

News reaching us from Florida that because of inclement weather forecast tomorrow, the final-round tee-times will be brought forward to between 0800 and 1000 local time, which is 1200 and 1400 GMT.

They will also go out in threeballs.

Terrific effort from Tommy Fleetwood as his 24-footer for birdie at the 13th stops inches short of dropping.

He's followed in for par by partner Jake Knapp who isn't going anywhere either.

Here's a bit of Akshay Bhatia getting his round back on track with a second successive birdie with a chip-in from a bunker on the eighth.

The 12th is just 326 yards today but neither Will Zalatoris or Lucas Glover are interested in having a pop at the green from the tee as they both lay up and trust their wedge game.

And it yields a birdie for Zalatoris as he dead arms a wedge to 15 feet and duly pours it in for a three.

Bud Cauley speaking to Sky Sports after shooting six-under par to be the clubhouse leader at -11: "I grew up here in Jacksonville and came here every year as a kid so I have dreamed of playing here. To be here playing is really great."

On how he will stay in contention: "My ball striking has got better and I am putting really well. We've got some weather coming tomorrow so I will just try keep doing what I'm doing."

On the conditions: "It was tough. Every hole seemed difficult today, even the par fives!"
