The only player to win the Players Championship and The Open in the same year?

Jack Nicklaus, in 1978. That's about to change, unless Rory has one last piece of magic up his sleeve...

They’ll have heard the sighs in Dundee as McIlroy’s birdie putt on 17 misses.

Not like a man with a mullet to rip up the book of convention.

Cameron Smith has somewhat ruined the St Andrews party.

Unless, unless, Rory McIlroy can turn his driver into a magic wand...

What a week Cameron Young has had - and what a way to finish!

A simply stunning final round from Cameron Smith. He taps in for a closing birdie and cards a bogey-free 64 to finish at -20.

Yes, the conditions have been favourable, but that is easily one of the greatest final rounds in major championship history.

Flawless from start to finish. He comes home in 30. Unfathomable scoring for us mere mortals.

Young for eagle. Makes it!

Unbelievable. He finishes at -19. What a performance.

Viktor Hovland. Remember him? He goes first with his birdie putt and it's a good effort.

Now pupils are fixed on McIlroy.

After that stunner of a second shot, he has about 12 feet to go... stays left!!

McIlroy wafts his left arm as if to say 'turn ball, turn'. It refused.

Smith's putt from the front of the 18th green.

He's judged it incredibly well. Two feet for a birdie and he may just have clinched the Open Championship.

What a shot from Rory McIlroy. He has a chance of the birdie he so desperately needs.

Rory McIlroy had a serious stride on as he followed that drive, outpacing the media trying to scuttle into position along the wall. Fans are now spilling on to the course to try and watch after the Northern Irishman’s approach to the 17th green.

Been a few times today when Rory McIlroy has not got as close as he would like with his second shots.

This one on 17 probably couldn't have been much better.

Still there is a lot of work to do, but he's got a chance.

The noise on the Old Course must go north of 100dB after his ball kisses green.

The two Camerons receive a wonderful reception as they stride up the 18th.

Oh how they deserve it. They've been exceptional today.

What a hit from Cameron Young!

He drives the 18th green and he'll have a very makeable eagle putt to finish at -19!

We couldn't have asked for a more gripping climax to the men's major season.

Rory McIlroy on the 17th this week?

Par-birdie-bogey.

It's a real snog, marry, avoid situation right now for the Northern Irishman.

My word! Rory McIlroy nails yet another drive. Perfect contact, perfect line, perfect everything really.

The Northern Irishman fades it round the Road Hotel and onto the 17th fairway.

The feverish chat among the fans down there tells us that excitement is reaching kids-going-to-the-zoo level.

Then he will hear the cheer from up ahead...

Nerves of Australian steel. But Smith knows there is still work to be done.

Cam Smith, with the biggest drive of his life, on the 72nd hole of The Open Championship at St Andrews.

Boom. It's a cracking effort and it settles just a yard or two short of the green. Tough putt or pitch from there, though.

That is an UNBELIEVABLE par save from where he was in two.

His 12-footer drops and he shows little emotion, but he'll know how big that is.

Cam Smith, take a bow. Machine-like today.

Smith has left himself a 10-12 foot putt - he was very smart there giving himself a great chance for an easy par.

Young fails with his birdie try. Left it short.
