Bad start to the day for Europe, but can Paul Casey learn the lessons going down the 18th?

He's just drawn level with Brooks Koepka after a birdie on 17.

Keep your cool, Case. This is another tight one.

Rory taking his fifth shot, he finds the green, about 12 feet but he concedes.

He had loads of chances but Justin Thomas wins 1 UP.

First singles point to the US. 10-7 to Europe.

Suddenly there is a lot more focus on those middle-order Europeans.

Sergio Garcia has eased two up on Rickie Fowler at the turn.

Matches like those could be crucial.

Oh dear. Rory whacks his shot out the bunker and it careers down the fairway and into the water.

These closing holes are made for cool heads and Rory has lost his. Justin Thomas fires into the green and he's stuck it into six feet. What a shot.

This match is over.

Europe need a lifeline. Jon Rahm lobs one their way, bringing up some blue at the top end of the board.

Tiger Woods was in a world of trouble off the 13th tee and Rahm had two putts from 20 feet for the hole.

That was margin enough.

It gets worse for Rory McIlroy. His shot out of the bunker goes nowhere. He's still in the bunker. This might be over.

Thomas Bjorn trying to look cool in his aviators, but he's must be boiling inside.

Down the last then, and Rory McIlroy is in a bunker on the right of the fairway and it's plugged. Justin Thomas went right down the middle.

This is tense, and then some. Give me more chocolate! Only way I can cope.

Ryan: Great save from Rory McIlroy on 17. Would take an A/S on first match.

Nathan: Sitting in work this weekend and Rory is doing Ulster proud. Go on Rory! Get us those points on the 18th.

Nick: It's not true that Phil Mickelson has a number of Parisian bus companies on speed dial. Jim Furyk has confiscated his phone.

Jordan Spieth starts on the long road back into his match against European surprise of the day Thorbjorn Olesen, with a par putt dropping on 10 to cut the arrears for four.

Well... there’s the DJ emotion. What a putt for birdie at the 11th, and he fires his putter in the air in delight!

There was a real swagger about the American as he marched off after Ian Poulter’s birdie effort then lipped out as he tried to save the half.

The world number one has turned this around in the last couple of holes.

The projected overall score, based on current state of the matches, is 15-13 for Europe.

That lead is looking skinnier by the minute.

This is incredible. Dustin Johnson swapped his putter after a poor couple of days on the greens, and look at this. He's holed a 50 footer to go one up on Ian Poulter.

That's the putt of the day.

A little bit of love for Thorbjorn Olesen's performance....so far.

Here's Rory McIlroy at the back of the 17th in the rough, and he flops it up into the air and it rolls to five feet. Decent effort.

Justin Thomas has a 12-footer for a birdie, but it's short and he thwacks fresh air with his putter in frustration.

Rory to halve it from five feet. BOOM.

On we go to the last. Tasty.

Tyrrell Hatton bogies the seventh as he mis-reads a 14-footer. Patrick Reed is one up.

Bubba Watson bites back at Henrik Stenson on six with a birdie to take the hole and cut the arrears in half.

More American momentum at the bottom of the card as well.

Bryson DeChambeau has moved two up on Alex Noren at five.

Rory in trouble as the blue disappears from the top of leaderboard quicker than water down a plughole.

On 17, he's over-hit his approach from the rough to the back of the green.

Hear that snarl in the undergrowth? That is a Tiger on the prowl.

It took a while for him to get going, but the United States kingpin sinks a 12-foot birdie putt on the 12th to pull all square with Jon Rahm.

He punches his putter shaft in delight on his way off the green and Europe are all square at best in the top six matches.

No, you keep calm.
