Shane Lowry manages to stifle a smirk when his lands plumb on the green with a crisp iron shot on the approach to the ninth.

Moments later and Cameron Young does likewise for the USA.

What can Tommy Fleetwood do? He's 20 feet away. And knocks that up to gimme length.

So it's over to the main man in this pairing so far, Justin Rose.

HE WALKS THAT IN!

That's his sixth birdie in eight holes. Incredible from the Hampshire hero.

Sam Burns is muttering to himself after dunking his approach into six into the front bunker from the right rough.

Patrick Cantlay provides the backstop mind, zinging his iron into around 18 feet.

A huge shout of 'Tyrrell Hacker' goes up as Tyrrell Hacker takes on a similar shot and spins it back to 10 feet or so. Matt Fitzpatrick's just outside his team-mates ball after taking a wedge.

Hatton's uphill putt stays high and slips past. This is going to remain all square.

Now Scottie Scheffler. And his effort comes up three feet short. So work to do for the Americans' threes.

The action out there is spellbinding - but some of the scenes in the crowd have been less so.

On the big scoreboard, that is prompting the boos here, they have put up spectator etiquette warnings and a zero tolerance policy.

They have put up two pages of that and the gist of it is that anybody who does it is on their way out.

Those messages are now going around the course as a result of what is happening in the top match and the stick that is coming the way of Rory McIlroy and Shane Lowry.

And it's Bryson DeChambeau who is first to putt on the eighth.

That was really tricky to be fair but he did not get any sort of connection on it and it almost seemed like it was a double hit.

That used to be a penalty but not any more.

Should be said that Lowry and McIlroy, other than when they have been put off their shots, don’t seem too fussed by the flak.

The pair walk off the tee laughing at something which has tickled them.

"Oh, he’s loving it," one of Lowry’s team chuckles to me.

Suppose these golfing superstars learn how to have blocked ears - even when they’re getting comments about former girlfriends and their weight.

It's a seven iron from Bryson DeChambeau at the par-three eighth but it goes through the back and rests against the collar at the back.

Absolutely nothing in this match at all. Europe's makeshift pairing could and perhaps should be ahead but it's another hole ticked off without any real major errors and a couple of pars means it remains all square.

Here are some of the scenes earlier when Rory McIlroy was trying to putt.

Great putt from Sepp Straka on six to grab a half as Xander Schauffele is in nice and close and has no problem dropping that in to the cup.

There's rightly all eyes on Rory McIlroy and Shane Lowry right now but there's three other matches out on the course and they're all vitally important.

Europe have a big lead but how big will it be by the end of this sessions?

Cat and mouse on the green on the eighth, but neither the European pair nor the American duo are able to pinch the hole.

Shane Lowry has the best chance to win it but his putt just flashes wide. Justin Thomas sinks a tricky putt to halve the hole.

Lowry and Rory McIlroy still one up for now.

This is interesting!

Oof, that putt from Bryson DeChambeau really burned the edge of the hole but it does not drop and that is a big opening now for Justin Rose.

He lines it up in his usual routine... and it was never going anywhere else but middle of the hole!

Yet ANOTHER birdie for the Ryder Cup stalwart and we are back to all square in match two.

Not seen any fans been ejected yet - and still being told by police that they’ve not had to remove anyone crossing the line.

One of the European team, however, has just been chatting to an officer, seemingly pointing out someone he thinks is being unruly.

Rory McIlroy is receiving more stick. One guy tells him he can’t “keep running” to the referee

Justin Thomas raises his hand to urge silence before McIlroy’s putt.

There is a gap for Scottie Scheffler among those trees, but can he take most of it? Not quite. Into the greenside rough for the world number one and he is going to have a nasty stance there.

And how about that from Justin Rose?!

The Englishman looks to be over his minor blip and takes dead aim at the flag to land it seven feet to the right.

Chance to get this all square once again coming up...

It's tense in the crowd and it's tense on the course right now.

All four pairings very close.

JJ Spaun misses a decent chance to take the lead with a 12 footer for birdie on the fifth and Jon Rahm takes advantage by grabbing the half to keep the match level.

None of this group are quite firing just yet to be fair, and if one of them can they can take control of it.

Luke Donald has clearly been called up to this green and he's stood there now with his arm around Rory McIlroy.
