There's another birdie for Thomas Pieters!

He judges his 20-footer on the par-five 14th perfectly, starting it well outside the right and letting the slope do its thing.

Pieters is seven-under for the day and just four off the lead!

Bryson DeChambeau had quite the roller-coaster today, as he explained to BBC Radio 5 Live:

"There was a bit of everything - I was glad to get in at 5 under for today."

Putting drills last night:

"I was working on launching the ball better, and I have never been good at these drills. I was working on launching it better and this morning it felt decent."

What happened on the 16th?

"The tee shot was fine. I tried to play a cut and cross to the left and it was difficult to get my head wrapped around a 120 footer. I didn't launch it very well - it derailed me a bit."

Spent a lot of time on very detailed putting drills:

"I have always wanted to get better whatever the situation. I am still going to work my butt off to be the best I can be, no matter what the golf tournament is."

Could we be seeing some low scores today?

"I definitely think the leaders can get to -15/-16 definitely - makes things hard on me but perhaps I can go out and shoot a -9 tomorrow."

It looked like Bryson Dechambeau might be the day’s big mover after reaching the 14th tee six under for his round. Then I joined him.

A grotesque four-putt double bogey on 16 killed his momentum. The American, who was met with good-spirited boos after pulling out an iron on the tee, slashed his shot left but found the green with his second. I’ve had Uber journeys a shorter distance than the first putt, but he was still close enough to save par. He didn’t.

Another eventful par at 17 was followed by a snap-hook iron on 18, then a delightfully floated chip to end with birdie for a 67. He’s surely out of the picture at six under, though.

Another birdie chance for Will Zalatoris on 10... oooh, agonisingly short.

Another roll or three and he'd have muscled in on the eight-under crew.

The American looks exasperated. That's because, even though he is three under for the day, he's also left a few putts an inch or two short.

Lowry's eagle on the par-four ninth is the seventh of the third round! There have been 29 birdies and 14 pars.

Just the one bogey from the first 51 players to complete the hole so far - England's Jordan Smith with that.

Hello pop-pickers, there's a new entry in the charts.

As we've just told you, Thomas Pieters has moved among the frontrunners and that means the leaderboard looks like this...

-13 Cameron Smith (15:55)

-11 Cameron Young (15:55)

-10 Rory McIlroy (15:45)

-10 Viktor Hovland (15:45)

-9 Dustin Johnson (15:35)

-8 Scottie Scheffler (15:35)

-8 Tyrrell Hatton (15:25)

-8 Thomas Pieters (13)

Shane Lowry's had a frustrating week with the putter.

The solution? Just rely on the wedges. The Irishman finds himself in the wispy rough left of the driveable ninth green, but connects beautifully with his chip.

It lands well short of the pin but keeps rolling...and rolling...and IT'S IN!

It looked like the ball had just run out of steam, but it falls in the left edge and that's an eagle for the 2019 Champion Golfer of the Year.

That'll do nicely.

Always good to see young talent blossoming.

And who'd have thought Happy Gilmore's caddy would have turned to a perennial major challenger.

Will Zalatoris is always in the hunt these days and moves up to seven under with a birdie on the ninth.

The young American is out in 33.

Thomas Pieters, who won in Abu Dhabi in January, is going as well as anyone out there.

The 30-year-old Belgian has just birdied the 13th to move six-under for the day and eight-under for the championship - and with a par-five to come.

The 2016 Ryder Cupper has a big chance to post a low one.

The spectator village was packed hours before the leading groups head out, with a one-queue for the shop and the seating areas outside the bars crammed by 11am - there’s the classic Open Arms, but you can also choose to get a drink in the Wedge, the Slice, the Hook or the Birdie. Which one suits you best?!

Cameron Young has very much gone under the radar - he's relatively new but he has major championship golf within him.

He seems to be a bit of a dude. He seems to take most of it in his stride, when he shot that amazing first round, he was just so chill.

Back to his golf, he just takes these tight shots on.

Move over Scotty, there's a new Cameron in golf town.

Actually, there are two. Messrs Smith and Young.

Feels fitting that a Scottish name is occupying the top two spots of the leaderboard at St Andrews.

Cameron's origins are apparently from the Gaelic words 'cam sron', which means 'crooked nose,' or “cam abhainn” which means 'crooked river'.

Thanks Internet.

Wonder what Tiger Woods is up to today?

The 15-time major champion missed the cut on his favourite golf course and the 46-year-old, who speculated the next Open at St Andrews might not be until 2030, does not know if he will be back in competitive action.

That led to emotional scenes as he walked up the 18th yesterday.

"It felt like my last time," said Woods, who wiped away the tears.

American Kevin Kisner says the pin positions are more accessible today.

Easy to say that when you've shot a 65, which features nine birdies.

The pins are not on as many slopes, according to Kisner, leaving straighter putts and therefore better chances of birdies.

Cameron Smith, of course, goes out in the last pairing and will be stepping out onto the first tee in little over an hour.

Here are the business-end groups left to come...

14:50 Matthew Fitzpatrick (Eng), Min-Woo Lee (Aus)

15:05 Si Woo Kim (Kor), Sahith Theegala (US)

15:15 Patrick Cantlay (US), Adam Scott (Aus)

15:25 Talor Gooch (US), Tyrrell Hatton (Eng)

15:35 Dustin Johnson (US), Scottie Scheffler (US)

15:45 Viktor Hovland (Nor), Rory McIlroy (NI)

15:55 Cameron Smith (Aus), Cameron Young (US)

If you didn't know who Cameron Smith was, you'd be forgiven for thinking he's a fella who is getting ready to serve margaritas at a Byron Bay beach bar.

The mulletted leader has arrived at St Andrews, wearing a bright print shirt, baseball cap and backpack carrying the essential items.

Super cool in the St Andrews heat.

Channeling my inner Carol Kirkwood to confirm for you it's very hot today, certainly by the east coast of Scotland's standards, although every now and then the breeze picks up.

Playa de St Andrews is looking glorious and lots in the media centre are slapping on the factor 50 before heading out to follow the leading groups, could do with an ice cream pit stop en route.

Here's how things stood at the end of play yesterday - and how the first page of the leaderboard still looks.

-13 Cameron Smith (64)

-11 Cameron Young (69)

-10 Rory McIlroy (68)

-10 Viktor Hovland (66)

-9 Dustin Johnson (67)

-8 Scottie Scheffler (68)

-8 Tyrrell Hatton (66)

It's Moving Day at the Old Course and while it may be another hour and a bit until the leaders tee off, we've already seen several of the earlier starters ripping up the links.

American Kevin Kisner, who was tied second at Carnoustie in 2018, was in the second group out this morning and he carded nine birdies in a sizzling 65 to give us a flavour of what's possible out there.

The Europeans are also faring well, though. Italy's Francesco Molinari, who denied Kisner at Carnoustie, fired a 66 while big-hitting Belgian Thomas Pieters and England's Tommy Fleetwood have made significant moves up the leaderboard.

Bryson DeChambeau was six-under for his round through 13, but a double bogey at the 16th is a reminder that while there are plenty of birdie opportunities, lapses in concentration will be punished severely.

The seagulls aren't the only ones planning to fly at St Andrews today.

So too are the world's best golfers.

The third round at a four-day golf tournament is traditionally known as 'Moving Day'.

That's because it is the day when those who harbour serious ambitions of lifting the trophy on Sunday evening need to manoeuvre themselves into a position to strike.

The overnight leaderboard is a who's who of modern-day golf but there are a few already swooping in behind them...
