Come on then Rahmbo, your people are expectant.

Another big lash of the big dog and the ball-tracker goes off like a jet stream.

Like Scheffler, straight on to the fairway.

Sunday singles is up and running, ladies and gentlemen!

Sit down, strap in and enjoy the ride...

A warm embrace between Rahm and Scheffler illustrates the respect between the pair and the spirit which this game will be played.

Scheffler manages a smile as each of the practice swings are cheered, then a thumbs-up when his name is announced - among more boos.

Now it is show-time...

Boom! If Scheffler is nervous it doesn't show in his opening drive. On the fairway.

Luke Donald has sent out the heavyweights here to get the game going. it looks like he's going to go top heavy and I expect at least four points out the first six and to get the job done early.

Your handy cut out and keep guide. The pin positions on the driveable par-four 16th and par-five 18th could be sensational if any matches get that far.

If we were in any doubt about how the Americans would be greeted today then we've just found out.

A loud chorus of boos when Scottie Scheffler strolls out.

Jon Rahm is greeted like Francesco Totti at the Stadio Olimpico. A hero's welcome.

Jon Rahm has come out with his game face on. Focused does not even cover it.

Wonder what shape his opponent Scottie Scheffler is in?

One of the images of this Ryder Cup was the world number one sobbing after getting hammered in the foursomes yesterday.

Even the coldest of European hearts had to feel for him. Right?

The ringwalk of the opening pair is under way...

Is there a sporting event in the world which doesn't play Sweet Caroline in 2023?

The omnipresent Neil Diamond song blasts out, rabble-rousing the thousands of punters who are horseshoed around the first tee.

"Touching me, touching you..."

But will it be so good for Europe or the Americans?

A fan dressed up as Mr Blobby getting a lot of love on the first tee. I’m not sure how well the character spread across Europe way back in the early 90s. Lots of bemused faces around me.

But hey it’s time for the Diamond again. I used to love this song.

On the incidents from the last match on the 18th hole to the altercation in the car park:

I’ve never seen anything quite like that, certainly not from Rory McIlroy. He’s a passionate competitor and clearly he was very riled with what happened on the 18th. It did reach boiling point last night.

It’s going to go down alongside the Brookline controversies in 1991 and 1999. We will be talking about Saturday night’s events for a very long time. It’s gone into Ryder Cup folklore, infamy – however you want to put it.

It has set up this final day which otherwise could have looked rather tame if Cantlay hadn’t made that putt, then Europe would have been even further ahead and it would have felt like a procession.

It doesn’t feel like that now, and it does feel like there is needle between the two camps and there is going to be a lot of incentive on both sides to make a point with the golf clubs.

Last night's antics have certainly spiced things up a little bit going into Sunday singles.

The scenes last night - like a boozy slanging match in your local town/city centre on a Saturday night - have added a bit more fuel to the fire.

How will that affect the golf today? Luke Donald's team-talk already done and Europe to rip through to 14½? Or the Americans to put up a fight (metaphorically not literally, maybe)?

The United States might be claiming to have the momentum after Patrick Cantlay's extraordinary win alongside Wyndham Clark on the 18th in the last of Saturday's fourballs, but history is against them.

Since 1979, only four of the 21 Ryder Cups have seen a team overturn a deficit going into the final-day singles.

In 1993 the USA won from being one point behind, while Europe came from two back to win in 1995.

The record comeback is by four points and has been achieved twice.

The first was the so called 'Battle of Brookline' in 1999 when the US started 10-6 down and won the singles 8½ - 3½ to win 14½ -13½.

Europe performed the 'Miracle at Medinah' in 2012 to equal that feat. They also trailed 10-6 and won the singles 8½ - 3½ to win 14½-13½.

Hit those thumbs - up for Europe to close out, down for US to stage the mother of all comebacks.

Zach Johnson will no doubt be trying conjure up memories of the USA's epic comeback in 1999, when Ben Crenshaw said the night before "I got a feeling" and the current skipper feels the same.

"We've got 12 guys; we've got 12 points," said Johnson. "I believe every 12 - every guy on my team can win a point. I'll just say that."

The United States have traditionally been stronger in the Sunday singles matches.

But in the US v Europe era that advantage is not particularly wide with the US collecting 133 points to Europe's 119.

Over the 21 matches played since 1979, that averages out at a smidgen over half a point (0.67).

At the end of all that nonsense, Europe still only need four points to win the Ryder Cup.

Little surprise then that the big three Jon Rahm, Viktor Hovland and Rory McIlroy are out in the first four groups.

We've got some tantalising pairings on the menu.

The old stager.

Great to see Justin Rose sinking putts to win Ryder Cup matches.

It’s a bit of deja vu on the first tee as Nicolas Colsaerts leads the crowd in an Icelandic thunderclap before a Mexican wave forms that ripples out of the first tee stand and down both sides of the fairway all the way down to the green.

It’s stirring stuff as the obligatory Europop kicks in and the stand starts shaking.

Luke Donald is not letting all the controversy get to him or his players, and still fancies Europe's chances.

"I'll give them the right messaging, and they will be ready to play," Donald said last night.

"We are five points up. We are in a great position. I've watched these guys over the last couple days compete with heart, with unity. They are all playing pretty good golf, to be honest. I really like our chances."

One of the most abiding scenes of the 2023 Ryder Cup will be legions of fans twirling caps round their heads in honour/in mockery of Patrick Cantlay.

The rumour yesterday was that the world number five refuses to wear a team cap of a dispute about the team not being paid to play.

Cantlay's response?: "The hat doesn't fit. Everyone knows that."

Rory McIlroy was not impressed with the US celebrations after Patrick Cantlay drained his 45-foot putt to win the 18th hole last night.

The American's caddie danced in delight, waving his cap around, while McIlroy still had a birdie putt to halve the hole and end the match all square.

It all got a bit heated, including some slightly unsavoury scenes in the car park.
