Only nine men under par as I write, plus some pretty ugly scores. Master's champion Danny Willett bogeys eight and nine and is now three over, Rory McIlroy is out in two-over 37. Both men with pretty ordinary approaches at 10.

Landry at six, for birdie... lips out, he stays five under and clear by two. Westwood leaves his par putt right of the hole at the first, his 10th, to drop back to -1.

Bubba Watson for par at 11 and that's a doozy, feathering it in to stay -2. Spieth with his second at 18 and that's bang into the heart. DeChambreau is in the rough out right and he can only thick it into a greenside bunker. The rain has made that jungle even messier.

Here's Westwood from the fairway on the first, his 10th. He pushes it a touch and he's on the front right edge of the green. A solid nine needed Lee. Up on the sixth and Landry hits a dream shot into the 206-yard par three. He's got a 15-footer for another birdie.

On the ninth McIlroy dribbles a lengthy birdie putt just wide and he's got three feet coming back for par. Rickie Fowler on the same hole, bending one from the other side of the green but not borrowing enough. Willett's birdie putt races through the break.

DeChambeau flops a wedge, Mickelson-esque, over Spieth's bunker to five feet and then Spieth flicks his effort a foot inside that. Remarkable shots, no doubt helped by the rain-soaked receptive greens. DeChambeau in for a birdie. Can Spieth follow? He's up to one under.

Landry misses a birdie putt on the fifth to stay five under. Willett into the heart of the ninth to set up a birdie sniff from 25 feet.

Lots of players hanging around, waiting to hit their next shots. Apparently there's one player yet to reach his ball and that's causing the delay. No names at this stage. The clouds above are the kind of dark grey you tend to find hanging over a gritty northern mill town. I'm not convinced we're going to get too much more play, but the klaxon has sounded and here we go...

Here's what the ground staff have been up to after all that rain

Jordan Spieth, who, along with playing partners Bryce DeChambeau and Zach Johnson, had a rules official in his ear over slow play on the 16th, is back out on the course. 

He had just hit his approach to the 17th and watched his ball spin back past the hole, off the front of the green and into the deepest of deep bunkers. "You've got to be kidding me! How is that in the bunker?" he had exclaimed, along with a mild profanity before the hooter sounded.

Quite right Jordan. Play.

As well as thunder and lightning, we now have standing water on the greens. We will not have play for a while yet, if at all...

I'm told there might be a restart in 30 minutes, although USPGA officials have warned of a "pop-up" storm, which apparently are very popular in London's trendy Shoreditch. Meanwhile, players are unable to practice on the range, because of the threat of lightning.

Righto, no point updating you up on nothing, so we'll be back again when they're back out on course. 

So after another break for the rain, let's take a look at the leaderboard...

-5: Andrew Landry (13*)

-2: Bubba Watson (10), Danny Lee (8), Lee Westwood (9*), Bryson DeChambeau (7*)

-1: Romain Wattel (11), Kevin Strrelman (11*), Matt Fitzpatrick (8), Harris English (8*), Zach Johnson (7*) 

Selected others:

E: Shane Lowry (7*), Jordan Spieth (7*), 

+2: Paul Casey (9*), Rory McIlroy (8), Danny Willett (8)

+3: Rickie Fowler (8), 

+4: Luke Donald (9*)

Fans flee for shelter as the rain starts to come down at Oakmont.

Lightning forecast. Oh dear.

"I've never known someone be so excited about watching Northern Ireland play football," quips Danny Willett, as playing partner McIlroy makes his way towards the clubhouse with indecent haste. Northern Ireland, of course, are currently in action against Ukraine. Lightning in the area, apparently, I will keep you posted...

I thought that was the hooter again but we think it's a passing train. McIlroy driving down the ninth, into the mist, and Willett follows him down there. Fowler with the big stick and we think he's found sand... and that is the hooter, it looks bleak out there to be fair...
