Tiger Woods has arrived at the course. He's in his Sunday red.

Will he be lifting the Claret Jug again later this evening?

The last three Open Championships at Carnoustie have needed a play-off to decide the winner, and with this year's final round beginning with a a three-way tie for the lead, it is again a real possibility.

Tom Watson beat Jack Newton in 1975, Paul Lawrie came through a three-way showdown with Justin Leonard and Jean van de Velde in 1999 and Padraig Harrington denied Sergio Garcia in 2007 via a four-hole aggregate play-off.

That same format will be repeated this year on holes 1, 16, 17 and 18, with sudden death following if needed.

After a difficult year and a bit since winning the 2016 Masters, Danny Willett has returned to form this week.

Starting at three under he may be too far back to challenge for the lead but a strong finish is still possible.

He has just got under way, playing alongside American Ryan Moore.

I wonder what was said in the American 'Frat House' last night.

A host of the top American players including co-leaders Kevin Kisner and Jordan Spieth are sharing digs for this week.

American Julian Suri is the hottest man on the course right now. He is three under through eight holes after birdies on the first, fifth and seventh.

That has him on three under, six shots off the lead.

Also on that score is Englishman Eddie Pepperell after two birdies in his opening five holes.

You would think Tommy Fleetwood needs to go low today if he is to stand any chance of winning his first major.

The good thing for the Englishman is he knows he can shoot in the 60s at Carnoustie, having set a course record 63 on the Scottish links last year.

"I can draw on the fact that I have low rounds in me and success on this golf course," says the world number 10.

"I would love to have been a shot closer and that would feel a bit more in reach but you never know, it's a major and the wind is supposed to pick up tomorrow and if you are there or thereabouts you're never quite out of it.

"I will need help from other people but at least on a scrappy day I have stayed in there."

Rory, dressed in bright pink today, has moved on to practising some chips on the range.

Jordan Spieth is now sinking a few putts.

I have been watching Rory McIlory on the putting green and he has been practicing that three-foot pressure putt. And in the final round at Carnoustie, the pressure will be on.

How far down the leaderboard can a player still be considered a contender?

Well, Carnoustie has a history final round comebacks.

In 1999, Scotland's Paul Lawrie overcame a 10-shot deficit to win in a play-off. Now, that was after Jean van de Velde's infamous triple bogey on the final green.

And last time in 2007, Ireland's Padraig Harrington came from six shots behind before eventually beating Spaniard Sergio Garcia in a play-off.

The other lesser known American who is tied for the lead is Xander Schauffele.

The 25-year-old Californian has one major top 10 to his name - at the 2017 US Open - but has won twice on the PGA Tour and was tied for second at the Players Championship earlier this year.

He followed a 66 in the second round with a 67 yesterday, bettering the score of playing partner Rory McIlroy, to move to nine under.

Want to know my best Xander Schauffele facts? He was born in La Jolla, California to a mother from Taiwan who grew up in Japan and his father is half French, half German.

His grandfather played football for Rapid Vienna while his father Stefan was a promising athlete in Germany with hopes of competing in the Olympics before a serious car crash with a drunk driver.

Schauffele will play in the final group today, alongside Jordan Spieth.

Jordan Spieth is the favourite but there are two other Americans alongside him on nine under, tied for the lead.

Kevin Kisner has led this tournament from start to finish. He had a one-shot lead at the end of round one and was also tied for the lead after the second round.

The 34-year-old from South Carolina, ranked 33rd in the world, has been in this position before.

He was in front after the first three rounds of last year's USPGA Championship only to fall away with a 74 on the final day.

Could he win a major for the first time today?

Is the wind is proving a factor? Are the pins in trickier positions?

There are certainly a lot less red numbers on the scoreboard than there were this time yesterday.

On Saturday, the first seven players out of the hutch birdied the par-five sixth. Today, it was just five out of the first 25.

But then the par-five 14th is proving a birdie-fest. Of the first 13 through, 11 birdied it, one eagled but spare a thought for Si Woo Kim who somehow managed a bogey six.

American Patrick Reed's bright pink shirt is flapping around in the wind as he holes a putt on the fourth green. He's one of 11 men under par from the 46 players who have began their final round today.

A few players are currently two under for their rounds but no one has been able to put together something remarkable, like Justin Rose did yesterday, in these trickier conditions.

McIlroy is chasing his first major title for four years here at Carnoustie and maintains he is still in contention despite dropping four shots behind the leaders with a bogey on the 18th hole yesterday.

"I'm obviously disappointed after the way I finished, but I'm still in the tournament.

"I'm only a few shots behind. The wind is supposed to pick up a little bit. So it will make things interesting.

"I just need to get off to a fast start."

But what of the home nations hopes? Can anyone from these shores prevent it being a sixth consecutive American major winner?

Tommy Fleetwood and Rory McIlroy are the closest challengers, in the group four shots off the lead at five under.

Neither had the round they were after yesterday with Northern Ireland's McIlroy carding a 70 and Englishman Fleetwood a 71.

Justin Rose is a shot further back after his 64 yesterday.

It's been a beautiful morning in Carnoustie and a quick peek at the latest weather forecast would suggest it's going to stay that way.

It's sunshine all the way, with temperatures in the low 20s. The rain that had been predicted looks unlikely to materialise.

But what about the wind, I hear you asking...well, there's a stiff breeze out on the course right now, about 10-15mph, and it will get a little blowier as the day wears with gusts of up to 25mph.

Some of those a few shots off the lead would no doubt have been hoping for trickier conditions, but it's still a brutal course, regardless.
