According to the Golf Channel, external world number one Rory McIlroy has agreed to perform with the lads when they play in Massachusetts on 12 September. Could Rory McIlroy be the man to replace Zayn Malik in One Direction?

1D's Niall Horan brokered the deal when he caddied for McIlroy in the par-3 contest at Augusta earlier in the week.

In a bid to avoid crashing and burning on the final day, perhaps it's wise to take on board words from a former champion. Trevor Immelman, who missed the cut, has tweeted , externalsome advice for the final pairings.

It was four years ago that another 21-year-old was leading the Masters by four shots going into the final round, but it ended in a painful collapse as the brutal pressure of Masters Sunday took its toll.

The Northern Irishman's ball plopped into Rae's Creek, he hooked shots into the pines and looked, at times, close to tears. McIlroy crashed and burned when all expected him to win his first major. In sport, nothing is a foregone conclusion, I suppose...

It is the question which has many possible answers, when at one point there looked like only being one.

"The Masters has basically turned into a four man, 18 hole psychology experiment and each test subject is trying to plant his own seeds of doubt and/or confidence," writes Scott Michaux.

"There's the outsider... there's the guy with three Green Jackets already... there's the Englishman... then there's Spieth, the guy toppling records in wire-to-wire fashion."

While some golfers are tweeting pictures of bibles and mugs of tea, others are slugging away on the course. Welshman Jamie Donaldson has made a fine start - birdies on the third and fourth to go two under for the day, three over for the tournament.

Steve Stricker is also in the red thanks to birdies on the first and fourth, which negate that bogey on the third. The American is one under today and two over overall.

Everyone has their own routine before a big day. America's Cameron Tringale has tweeted: , external"Gospel, Greens, Golf. In that order #sunday #masters". The 27-year-old from California is one under.

Jordan Spieth is far too polite to reveal who he'd prefer to partner on the final day and he's probably too polite to boast about the records he's broken this week.

The young Texan's two-under-par 70 on Saturday left him on 16 under, a new Augusta record after 54 holes, and kept him on track to become the second youngest Masters champion in history behind Tiger Woods. And Woods's record score of 18 under, made in his never to be forgotten debut win in 1997, is also in danger. See, there's plenty of reason to keep an eye on today's action.

"Justin Rose, not taking anything away from what a great player he is, doesn't have the intimidation factor Phil Mickelson has. Psychologically, and dynamically, it's a little bit easier for Spieth to play with Rose than with Mickelson."

It's the final day, you're in contention to win the Maters, what would your morning preparations be? Meditation? A fry up? A quick chat with your psychologist? Tweet your suggestions using the hashtag #bbcgolf.

"Perfect start this morning!!" writes Justin Rose on Instagram, external as he enjoys an early morning cuppa. Wonder if he is brewing a plan to beat Jordan Spieth?

Right, where were we? Ah, yes, Justin Rose. The 2013 US Open champion gave the impression he had no interest in joining the cavalry as Spieth's pursuers began hunting down the leader on a marvellous moving day.

But he rattled off five birdies in the last six holes to close the gap on the American, putting himself in contention and dragging Spieth back into realistic striking distance.

Rose will partner Spieth in the final pairing (teeing off at 19: 50 BST) and the Englishman says going out last will be an advantage. "Jordan is playing some incredible golf, but it will be good to keep an eye on him and try to keep pace," he said.

As he has done on the previous three days, Northern Ireland's Graeme McDowell has posted day four's pin positions on his Instagram., external It might be of interest to you. But, then again, it might not.

Tim Marshall: I'm looking forward to the golf later it's going to be a close finish. Justin Rose to birdie early fingers crossed.

Paul Oakley: It's all crossed for Justin Rose in the final round of the Masters - a stellar back nine yesterday and it's all to play for.

Simon Pridmore: Good luck Justin Rose for the final round of the Masters.

Gethin: Tiger Woods and Rory McIlroy grouping on Masters Sunday - nothing better than that.

Perhaps this next little fact will help you decide on a winner because 20 of the last 24 Masters champions have come from the final pairing. So, with Justin Rose on 12 under par and Jordan Spieth 16 under, you'd perhaps be wise to bet on either the young American clinching a first major or Rose adding a second to his 2013 US Open victory.

If you've been stuck on planet Zog, or just had better things to do than watching grown men whacking a small pimpled ball with a stick for three days, perhaps you don't know a 21-year-old Texan by the name of Jordan Spieth has kept the history scribes busy with record-breaking rounds in Augusta and leads heading into the final day by four shots.

But there's a charging pack behind him, led by England's Justin Rose and including three-time champion Phil Mickelson. Exciting? Just a little.
