A reminder of who is coming up.

08:14: Jason Day, Rickie Fowler

08:47: Dustin Johnson, Phil Mickelson

09:14 Brooks Koepka

09:25: Patrick Cantlay, Xander Schauffele, Tiger Woods

09:36: Collin Morikawa

09:47: Matt Fitzpatrick, Shane Lowry

09:58: Scottie Scheffler, Jordan Spieth, Cameron Young

11:04: Daniel Brown

Justin Thomas, Rory McIlroy and Bryson DeChambeau are among those going out in the afternoon.

One of last year's surprise packages Sepp Straka is just getting his second round under way.

The Austrian finished second at Royal Liverpool on his way to nailing a place in Luke Donald's European Ryder Cup team.

Straka shot one under par yesterday and in these conditions, he'll be targeting a fast start.

Bryson DeChambeau is a deep thinker and I wonder if there is any history in that notebook of his.

At 11 shots back after round one, he'll be trying to emulate Harry Vardon from 1896 who overturned that to win in the largest comeback in Open history.

Whatever solace he needs. After all, Paul Lawrie trailed by 10 shots on Sunday and still won in 1999.

Doesn't happen very often though...

Bryson DeChambeau has been the best player at the majors in 2024 but his game deserted him for the front nine on Thursday.

Bamboozled by the changing wind, he also forgot to pack his putter, missing from four feet and three feet on holes one and four.

A penal double bogey on six really wrecked his card and he even confessed afterwards: "I could have thrown in the towel at nine".

But he didn't, and found a majestic 54-foot eagle at the 16th to get to five over par.

He says he's "excited for the challenge".

Even at 11 shots back, Bryson believes.

Plenty of American stardust dotted around the top of the leaderboard as they seek a clean sweep of the majors for the first time since 1982.

Xander Schauffele pays council tax for the top five at majors and he's there again, hovering around at -2.

Five-time major winner Brooks Koepka shot a one-under 71 and is hovering dangerously.

PGA Tour stalwarts Russell Henley and Chris Kirk have also got themselves in the mix.

You will notice the man in that picture below is not on the list though. More on him coming up...

I mentioned Marcel Siem before and he's found another birdie at the fourth to move into the red for the tournament.

When he gets there, he'll find another of the early starters Corey Conners who picked up a shot at the first.

Taking advantage of the pleasant conditions down the front nine so far.

It's worth remembering that Scheffler's season is the first year anyone has won six times on the PGA Tour since Arnold Palmer in 1962.

That year Palmer did get to seven - with victory at Royal Troon.

Omens, much?

It's hardly a surprise. Scottie Scheffler has made the top of leaderboards his domain this season.

And the world number one is firmly in contention after a carefully plotted opening round of one under par.

No doubt he's already planning to "stay in his lane" and leapfrog the competition, one by one.

I suspect everyone will be looking for where the hole is on the eighth... right by the coffin bunker is the answer. Take that one on at your peril.

Yesterday was brutal, wasn't it.

The field average is three-and-a-half shots over par - that's the most difficult first round at The Open since Muirfeld in 2013 according to stats guru Justin Ray.

England's Matt Wallace held the lead early on Thursday - in no small part down to holing out with this two-bounce eagle at the fourth.

Can't tire of watching this.

In fairness to Wallace as well, he kept up the pace throughout and deserved to be under par and inches from the top 10.

While Daniel Brown and Shane Lowry were making scenes at the top of the leaderboard, the other bogey-free round out there happened much earlier.

Justin Rose, England's wily head, plotted his way skilfully round Royal Troon in the tricky early conditions, making 16 pars and two birdies.

For a long time, he was one off the lead. He's got the nous and experience to stay in the mix this weekend.

Thursday's morning wave was mainly ruled by two-time major winner Justin Thomas who led for a long time at three under par.

Seven birdies, two bogeys and a double bogey made it a colourful and entertaining start for the American but he showed his resilience and class down the stretch to birdie his final two holes.

Last week, he made a blistering start at the Scottish Open with an eight-under 62, before falling away.

Time for something different JT.

Peter says the conditions are benign at the moment and German Marcel Siem is making the most of it.

He's two under through three holes and up to level par for the tournament.

In his news conference after round one, Shane Lowry said he was "pretty lucky" to have watched golf in the morning and been able to see the course "was not playing easy".

He made it look pretty easy in the afternoon.

It's an earlier start today so he may have to do a bit more figuring out as he goes along.

While the flags atop the huge grandstands flanking the 18th green are fluttering in the breeze, the flags on the opening greens are hanging limp.

The early starters need to take advantage of the conditions this morning, it's about as perfect as you're going to get on a links course.

Before Thursday, Ireland's Shane Lowry had never shot a round of 66 to open a major before.

He whipped round Royal Troon with some stellar iron play and superb putting, gaining 4.74 strokes on the field.

The Team Europe Ryder Cup star almost won the US PGA in May and knows how to plot his way round a wet and windy links course. After all, he did it in style in 2019 at Portrush.

His challenge continues at quarter to 10 this morning.

Sure, Dan Brown had a pretty astonishing debut round at the Open.

But he didn't quite manage this, did he?

Step forward 19-year-old amateur Jamie Montojo who plundered an eagle on his very first hole.

Dan Brown, 29, turned pro in 2017 and has a DP World Tour victory on his CV - last August at the ISPS Handa World Invitational in Northern Ireland.

But his 2024 has been difficult. He has missed the cut in six of his past seven tour events, including last week at the Scottish Open, and only qualified for The Open two weeks ago at West Lancashire.

It is not unusual for an unexpected leader after round one. Last year, amateur Christo Lamprecht shared the top with Tommy Fleetwood before finishing 76th.

The challenge for Brown is to back it up today - and at least there will be plenty of people out on the course to see him.

Want to see the world's best golfers master fiendish conditions on the Scottish coast?

Here's the pick of Thursday's action.
