Well, that was, er, strangely compelling. The quality wasn't the greatest, but we eventually saw some drama.

Thanks for sticking with us over the past 22 holes, see you later!

"I'm just trying to calm down, my heart can't take any more, it was such an incredible opportunity," Mickelson says.

"He's the greatest of all time but to have a little bit of smack talk for the coming years means lot to me.

"Because I don't have a lot on him!"

Dan Kitchingman: Well no matter the meaning of it. Golf under floodlights is pretty cool.

Got it! Phil Mickelson has NINE MILLION reasons to celebrate...

Leftie keeps his nerve to knock in the shortest of putts for the biggest of prizes.

Mickelson and Woods embrace after finally being separated after 22 holes.

Woods to go first with his birdie putt... goes right, stays right, leaves it short.

If Mickelson sinks this birdie putt, it is all over...

Phil's closer than Tiger! Mickelson is four feet away. This is the drama and tension we've wanted for the past four hours...

It's a surreal sight as both men gamble under the floodlights in the Vegas desert....

Woods isn't going to go long for a third time, that I can assure you.

Tiger finally nails his approach, leaving him with about seven feet.

Come one Phil, an ace will close this one out nicely...

Not yet. Mickelson concedes a four foot putt and they head back to the tee. "I don't wanna win like this," he says.

This is barmy.

...OMG! He's missed it. Mickelson goes after it, like you'd expect, and sends it whizzing past the cup.

Is this ever going to end?

Tiger, in the rough between bunker and pin, knocks on... looks good... just rushes past the left edge.

Woods is just inside Mickelson, but it will be irrelevant if Phil sinks this...

Tiger. Take two... he's gone long again.

He chunters.

Back to Phil... "There it is," says Leftie as his ball lands close. It sidles up to the hole pin high and leaves him with a six footer for the birdie.

One would think Tiger has to hole this...

"Oh no, I've not hit it!" Mickelson's reaction tell you everything...

Leftie doesn't give it enough beef and, although his ball tries to roll out, it's short.

Back to the putting green/play-off tee...

Woods knocked in from the fringe on the 17th.. he'd love to do that now. A good touch but it lacks the precision. And leaves Mickelson putting for the jackpot...

Matthew Vernon: Nicklaus v Watson at Turnberry. Stenson v Mickelson at Troon. Rose v Stenson in Rio. Those it ain't. Good grief.

Alter Ego: I’m following the Mickelson v Woods match via the BBC website's text commentary, which seems to be a lot more exciting than actually watching it on TV!

Those spectators get moved back before Mickelson has his turn, Leftie finding the dancefloor and left with a 15-foot putt. Still anyone's game this...

Tiger, who has been the better today with his short irons, goes first... knocking his shot long and hitting a spectator. That pushes his ball back on to the fringe...

Hold on a minute... we're just waiting for a new hole to be cut...

So, basically, we're down to a $9m chipping contest under floodlights...

Now the players have to tackle a makeshift '20th hole'. A tee box is set up on the practice putting green, in front of a stack of clear boxes containing the $9m winnings, with 93 yards to the 18th green.

Nooooooo! Tiger Woods has made a whole career out of nailing clutch putts. And now, with $9m on the line, he misses one.

Woods doesn't give himself a chance in fading light, his ball dribbling off to the left.

On we go!
