A great chance for a Brooks Koepka birdie missed by the American as he slides a 10 footer beyond the hole - a little too far beyond the hole for comfort actually as it leaves a bit of a stinky one coming back. But in it goes for par.

Disaster for Patrick Reed!

After a composed front nine, he makes a mess of the 10th and walks away with a double bogey.

He then pulls his tee shot on the 11th.

Unravelling a little here....

Rory McIlroy hits a delightful shot into the 251-yard par-three second, but he's tentative with his 22-footer and misses out on what would have been a glorious two.

The putts aren't dropping for the six-time major winner.

Ludvig Aberg visited the greenside bunker but splashes out and rolls in another confident-looking putt to stay out in front on his own, while Tommy Fleetwood follows him in for a three.

There really isn't much colour out there on the course yet, bar Brooks Koepka's pink stripes, but we've found another all-white to go with JJ Spaun from earlier.

Rickie Fowler, who will no doubt be wearing his statement orange on Sunday and has just closed within two thanks to a birdie at 11, is also decked in white.

When I asked you if you could pull of this style, most of you said absolutely not.

Works for Rickie though...right?

American Patrick Reed shoots a front-nine 34.

A couple of birdies on the back nine could help him take control.

That'll feel good for Tyrrell Hatton as he drains a 21-foot birdie to inch back to one over par.

He's been grinding today and if it wasn't for that nightmare hole at 18, he'd be right up there.

Uh oh, even the world number one is struggling to win the battle with Shinnecock Hills here, as Scottie Scheffler makes a double bogey on the eighth to drop back to three over for the tournament.

That's the same as playing partners JJ Spaun, the defending champion, and US Amateur champion Mason Howell.

Need a wind check at Shinnecock?

You could study the flags scattered across the property.

Or you could just look at Tommy Fleetwood's 90s-inspired trousers.

The wide-leg cut trousers have been fluttering magnificently all afternoon, providing a real-time visualisation of the 35mph gusts sweeping across Long Island.

Oh yes! Ludvig Aberg rolls in his second 30-footer of the day to move back to two under and into the lead on his own. Not a bad way to start his back nine.

Rory McIlroy, from slightly closer, races one past the right edge but makes the return putt for par.

But it's a poor bogey from Tommy Fleetwood, who three putts from 25 feet and slips back to one over.

Americans Sam Stevens and Ben James may not be well known, but they are both one under.

Stevens is world number 54, while James is playing in his first US Open as a professional after completing an All-American career at the University of Virginia.

Can either of them stay near the top of the leaderboard?

Sam Burns is a little short of the green with his tee shot at the second so needs two putts to secure his par.

It's a three for playing partner Tyrrell Hatton too.

You go on and on all day about how much a guy's putting has improved, and then Brooks Koepka goes and ruins it by missing a tiddler from four feet to make bogey.

He never looked comfortable stood over it, never looked happy making the stroke and the ball never got close to the hole really. Apart from that....

Thanks Gavin. That's the the guy I stuck a picture in of earlier!

It's a windy day out there - and it's not just golf games that are getting blown away.

Spare a thought for 18-year-old Hamilton Coleman.

The amateur played nine holes in practice with Rory McIlroy yesterday and soaked up every minute in the sunshine.

Today he’s 10 over par through 13 holes as Shinnecock starts to show its teeth.

Giant Swede Ludvig Aberg is up at the top of the leaderboard and he's just been joined by another Scandinavian in Kristoffer Reitan.

We mentioned him a little earlier and he's just birdied the second, his 11th, for a share of the lead.

How's your luck JJ Spaun? The defending champion just finds the edge of the green on the seventh with his tee shot, but then a strong gust of wind blows his previously settled ball off the putting surface, down the hill and into the bunker!

He has to play it from there I'm afraid, but he plays it amazingly do flick the ball out of the sand and roll it in for a par - that's how to deal with a bad break from the golfing gods.

Graeme McDowell's day has become increasingly tormented. He's followed a bogey at 18 - his ninth - with two more dropped shots at the first and second.

Four bogeys in five holes.
