Very scoreable conditions at present and a host of players are taking full advantage.

Expect there to be plenty of movement on the leaderboard over the next few hours.

Although maybe not for Sebastian Munoz, who played out of the sand and stuck his ball behind some wispy prairie-like grass left of the first green. He tries to blast his ball through but sees it shoot out only a few metres into another bunker.

Horrendous start.

Cameron Smith take a bow. The Australian sinks a 40-footer on the first to move within a shot of the lead.

Did the group behind hear the roar when that dropped in?

The leading group are under way.

India's Anirban Lahiri has the honour and pings his ball straight down the middle of the fairway.

Sebastian Munoz doesn't like his opening fourth-round shot, screwing his face as his ball heads right and across into the fairway bunker.

Exemplary stuff from Doug Ghim, who heads down to where Lahiri's ball is positioned.

Yes Sergio....

The Spaniard zips his second into five feet to claim back-to-back birdies.

The wind has picked up a little this afternoon and grey clouds have rolled in. There’s about enough blue up there to make a handkerchief as my dear old grandma used to say.

I see six-time major winner Nick Faldo was tipping Will Zalatoris to challenge.

The American opens with a double and then only cards a par on the par-five second. A cut and dried case of commentators curse.

Tommy Fleetwood has a long eagle putt at the second but ends up with par. Far from ideal and nor is that, clipping his approach to the par-three third well past the putting surface into the rough.

It's going to be another bogey.

Anirban Lahiri is 34 and has played on the PGA Tour since 2015. He has won $6.4m in those seven years, without winning a tournament. He's ranked 322 in the world.

He was born in Pune in India and when asked how the TPC Sawgrass Stadium Course compared with what he grew up playing on, he laughed before replying: "I'll invite you to come and play the courses I played growing up. It doesn't compare.

"We do have some good golf courses in India, don't get me wrong, but I grew up playing on Army golf courses.

"To give you an example the first junior event I played at the age of 10 at Royal Calcutta Golf Club was the first time I ever played on a no-preferred-lie golf course.

"That's when I was 10 years old. I grew up with an inch and a half on the fairways at the Army clubs, so just seeing a ball sitting down flat on the ground was a little intimidating.

"I had to ask my dad to buy me a 7-wood because I wasn't sure I could get it up in the air. I'm just being honest."

Ian Poulter finds the water on the 17th. The first man to do so there in this final round.

He walks over to the drop zone and precedes to loft his third right at the pin, seeing it spin back to about 12 feet. If only he'd done that at the first time of asking.

Rory McIlroy may have zero hope of adding to his 2019 victory here but that hasn’t stopped hundreds of fans gathering round the 10th tee, despite the leaders going out at the same time off the first. It’s three deep. The phones are out.

Doug Ghim is making his 69th career start on the PGA Tour and his second at the Players, where he has got on very well.

The best 54-hole positions of Ghim’s career are tied for second, in the 2022 Players Championship and blieve it or not, tied for third in the 2021 edition of the Championship, where he eventually finish in a tie for 29th.

Huge cheer for Shane Lowry on the first as he blasts his tee shot down the right side of the fairway.

That should give him a decent angle into the pin which is on the left side of the green 130 yards or so further on.

Not the start Tommy Fleetwood is looking for. He smashes his tee shot miles left on the first then completely shanks his second from the rough.

Hit third gives him half a chance of a scrambling par but it's not to be as he slides a short-range putt past.

Paul Casey speaking to Sky Sports prior to the fourth round: “I thought I had left the shore I thought it was going to stay six inches short. I was just happy to hit the green [on 17th] and get off with a par let alone a birdie, the golfing gods are paying me back a little this week.

"I love Pete Dye architecture, sadly he has passed away now but where I played at Arizona State was a Pete Dye golf course and it was my introduction to the sleepers lining the water. He plays a trick with your eye and loves to intimidate a golfer standing on a tee but is quite accommodating when you get down there.

"I learned a lot at Arizona State in terms of how to play his courses and maybe this is his finest. It is a joy to play this golf course, it is playable for ourselves and amateurs. It is a must-play course.

"It is maybe the strongest field in golf. It doesn't suit one style of play, you never know but you have to play unbelievable golf to be a champion round here."

Any slim hopes that world number one Jon Rham has of making an impression near the top of the leaderboard look to be up in smoke already.

The Spaniard's par, birdie, bogey start wasn't too bad but he then throws up a nine on the fourth.

And yes before you ask there was water involved!

While we wait for the main contenders to finish their last-minute preparations American Russell Henley has hit the heights on the 11th.

He holed out from 240 yards for albatross which is the sixth at the Players Championship since 1983.

Given he'd started his final round with a bogey, it was very welcome as well.

Shane Lowry is, perhaps, my new favourite golfer.

As all golfers know, if you score an ace, you buy a round in the clubhouse.

And after knocking in a hole-in-one on the par-three 17th on Sunday, he sent a little gift to the media tent...

Other beers are available, of course, but I wonder if Viktor Hovland will oblige after his ace on eight a little earlier today...

Aside from the honour of winning one of golf's biggest tournaments, there's a rather hefty pay cheque awaiting the winner.

Only two players have earned their first PGA Tour title at the players, New Zealand's Craig Perks in 2002 and South Africa's Tim Clark in 2010.

But could India's Anirban Lahiri make it three?

He gets under way with Sebastian Munoz and Doug Ghim at 17:01 GMT. Should he stay the course and win you'd have to say he'd have lived up to the sponsors logo on his hat and t'shirt.
