"Just imagine if he was to birdie 18. Three under could well win this thing."

Jim Furyk with an outside chance on the 17th for a birdie. The 46-year-old raises both hands in the air as the hole stops his ball from rolling any further. Five birdies and no bogeys. A par down the last for a clubhouse target that will take some matching.

Straight to the 18th tee and the American leaks it out right. The ball falls between two bunkers but disappears from view in the four-inch deep rough.

"I fancy Dustin Johnson to win because you have got to hit fairways and you have to hit greens and nobody has done that better than Dustin this week." 

Dustin Johnson is looking game. Remember he has never won a major. He took a break from the game not so log ago to confront personal issues and yet here he is once again in the mix on a major Sunday.

A good putt from the fringe leaves him five feet to save par on the eighth - a hole so hard players are tweeting to moan about it.

Ok they don't, but the holes do have ears. As Ian Poulter points out, players should be careful what they say after they sink or fluff their putts as we'll be listening!

Just look at the arrow, top left.

The Sergio Garcia fist pump is out more than a referee's whistle in France right now. 

He tiddles a soft touch down a hill to save par from 10ft on nine. Remember he found some heavy rough off the tee.

Not even the big hitting, swashbuckling Dustin Johnson can get close on the eighth hole. A 299-yard par three, he's short of the green.

Shane Lowry is well placed on the seventh fairway and takes what looks like a seven iron, drawing in from right to left, solid but unspectacular to find the heart of the green.

Jordan Spieth, the defending champion, finishes up with a bogey five for a nine-over total. The world number two never really got going this week. Back-to-back 72s saw him at four over at halfway.

A level-par 70 on Saturday and five-over 75 concluded a disappointing week for the two-time major winner.

Daniel Summerhays at 32 has never won on the PGA Tour. He's level par and, such is the crazy nature of the closing stages of any major, he may have some hope here yet. A long par putt on eight is key though. This hole is stealing the dreams of so many right now and Summerhays is the latest on the list. Bogey.

The world number one Jason Day is still on one over as he stands over this par putt on 10. It's 14ft and troublesome to say the least... no.

Dustin Johnson is going about his business admirably one must say. Not a bogey in sight so far and his birdie putt on seven will snake from left to right, the American crowd are whooping and willing it into the cup... it's close... just skirts the front of the cup. That'll be par.

The lead stays at five under. 

Lee Westwood started the day at two under, bogey on seven takes him to five over.

This is the ninth time Oakmont Country Club has hosted a US Open.

The rugged course is split with seven holes on one side of the Pennsylvania Turnpike and nine on the other.

I read an article this week where a number of members of the 113-year-old club were quoted. They actively dislike low scoring and want this course to basically punch those who take it on in the ribs. Nothing easy, nothing gifted.

To win here you have to earn it and then earn it again. This week has been kind some would say. When Angel Cabrera won here in 2007 he ended on five over par.

Today, I think it's fair to say Oakmont is winning.

In 115 previous editions of the US Open only two players have lost a 54-hole lead of four or more strokes. Lowry's lead is now just one stroke.

His putt on the sixth green from some distance is good though and leaves a tap in for par.

On his way to the ninth tee Sergio Garcia suddenly turns into Sir David Attenborough as he picks up a bird off the floor and hands it to a spectator. The little creature falls back to the floor so Sergio takes a mulligan and picks it up again.

That was warm and caring. The ditch his tee shot finds will be less so.

Scott Piercy had a blistering birdie-birdie start. Since then the American has played six holes, each in par. Solid.

Another playing well is Jim Furyk. Four birdies and 11 pars in his 15 holes today and the 2003 US Open champ is one under par.

The eighth hole, a long par three playing 299 yards today (yep, 299 yards) has given up just 23 birdies all week but Sergio Garcia makes it 24 in wonderful style from the sand.

It's a touch of Seve-style flair.

The club face is open, he whips the ball into the air and pitches it around three feet from the hole. That's daring and boom, in she drops. He's fist-bumping, yelling, this is Sergio at his best. Now, can he keep his head? He's in this.
