Let's have a look at Woods' CV... not bad, eh?

He's gone round this track in 65 a couple of times, back in 1997 and again in 2005. In case you're wondering what that did for him... he went on to win on both occasions.

And just like that, Tiger Woods is back in the game.

He tickles in for birdie at the seventh after that superb approach to within a putter's length of the pin - back-to-back birdies for the four-time champion.

He's two off the lead.

We have a three-way tie for the lead!

Webb Simpson joins the party with a birdie at 16 and he is flying right now - that's his seventh birdie of the day, accompanied by an eagle at the 13th.

Simpson is eight under for the day.

Tony Finau, 12ft for another birdie after an arrow approach into 10... doesn't hit it.

Xander Schauffele hitting it sweetly, gives himself an outside chance to pick up a shot on the par-three sixth. That'll be a downhill putt... break in it. Over to Adam Scott on the fifth - a lengthy par four - smashes it up the middle. Important to get them away long on those drags.

Back to Schauffele... drains it. Three men share the lead. There's a Tiger lurking and countless others.

Fantastic chance for a birdie at seven for Tiger Woods. He nails his tee shot to the middle of the fairway and then whips one pin-bound, taking it to within a foot or so.

Hollers all round from the patrons at seven.

Northern Ireland's Rory McIlroy speaking on BBC Two after finishing one under par for the day:

"Too many mistakes is the big thing, I made enough birdies and a couple of eagles and have just not been efficient with the scoring clubs, missing greens and not getting up and down and being a little loose from time to time.

"I’ve just got to keep playing to the end, I've got one more day to try and get myself up the leaderboard.

"I’ve been comfortable all week but just have not played the golf I’ve played in the last few weeks. I just have to go out tomorrow, try to post a good number, and move on."

Steady start for our final pairing - Francesco Molinari and Jason Day are level for the round through two. Both remain at seven under.

Quite incredible. Louis Oosthuizen probably woke up as a co-leader and thought "I'm in a great place".

He's started par-par-par-bogey and given just the one shot back but finds himself three behind Tony Finau.

It could change too as Tony Finau has just fizzed a stunner into the 10th green and this will be one he expects to put away.

Silence at the sixth as Tiger Woods weighs up his birdie putt, he rolls it above the pin and watches it break right at the last minute before disappearing into the cup. Lovely stuff!

Can Ian Poulter follow suit? He tickles the fringes and stays up. No such luck.

I can tell you Rory McIlroy signed for a one-under-par 71 and given he had a volatile front nine it's not all bad.

With all this crazy scoring going down we've overlooked Rickie Fowler and he has moved from three under to six under at the turn. He's lurking.

Will Tony Finau's pace be sustainable? If not there are plenty lining up behind him.

Zing. Adam Scott has just almost driven the green at the third. He's right up on the fringes.

The Australian can't make it count, he clips on and the leaves his birdie putt inches short. Par it is.

Now Brooks Koepka is cooking! Tee shot straight down the middle, deft approach to within a bin lid and ding, ding, down it goes. Birdie, birdie for the American. He's back in the hunt.

Word on the street is Tony Finau has taken 11 putts during his opening nine holes. Insane.

Tiger Woods at the fifth: Bogey, bogey... bogey! What is it about this hole? He just can't keep his tee shot in play here and inevitably it leads to another dropped shot for the American. His first of the day.

Ian Poulter from eight yards trying to avoid the same fate. Great save from the Englishman. A fifth successive par today.

Thirty is not to be sniffed at for Tony Finau. If he comes home in 30 he will be near the top of the leaderboard.

He has had a wonderful front nine.

Justin Harding had started the day with such promise, but the South African slips at the fourth... that's a bogey after back-to-back birdies. Back to seven under.

Tony Finau going like a rocket. An eagle at eight means he is six under through eight holes and he is one stroke clear at -9. Webb Simpson is seven under through 14 to get to -8.

But Patrick Cantlay's 64 is the low round of the week.
