Our Ken has been answering some of your questions on Facebook: , external

Tom Bohane asked: Is it true you once wrestled a polar bear, and won? Ken: The polar bear won on points!

Sam Koch asked What's your best round and favourite hole (and why) at Augusta? Ken: I managed to shoot 69 once. My favourite hole is the 13th. It's strategically very demanding and looks beautiful.

Phil Mickelson is in a cavernous bunker. he can't see the green from where he is so he just hits it as hard as he can but comes up well short. Rickie Fowler, wearing his traditional last-day orange, with an eagle chance on the 13th. It's a lengthy one, about 30ft, but that's no trouble for the American. Fowler four under for the day five under for the tournament.

Four shots the difference now between Justin Rose and Jordan Spieth. The Englishman has birdied two of the opening three holes so he can do no more.

The cameras choose to focus on Seung-Yul Noh, which means something is about to happen otherwise why would they show a player who is two over? He's in the bunker short of the 16th green... feather-soft touch... the ball lands on the green, a good dozen feet past the pin but it's Sunday at the Masters and we all know where that ball is going! Noh punches the air and the patrons cheer. Wonderful. He goes to one over for the tournament.

Birdie for Jordan Spieth on the third! The leader two under for the day and pops to 18 under for the tournament. All the young American needs to do is par every hole from here on in and he's equalled Tiger Woods' tournament record. It's likely Spieth is going to smash that record into smithereens.

Phil Mickelson is sporting an all-back outfit today and there is a reason behind it., external The American says it helps him "get more aggressive." He has done his research, the three-time Masters winner added: "Studies have shown that when NFL teams wear black they have more penalties." The big question is will black turn into green later?

Hello again, Aimee here for an hour. Ben has realised he's forgotten to wear his special Masters Sunday socks so he's dashed home to get them. Hopefully they've been washed since 2014 otherwise we're all in for an unpleasant back nine.

Back to the golf, Phil Mickelson is agonisingly wide with a snaked birdie attempt, groans around the fourth as the ball curls beyond the cup. Birdie for Ian Poulter on the seventh, though. The Englishman now six under.

A very studious Duncan Drysdale: Zoology revision for university finals and Augusta are in my books very compatible.

Vincent Leonard: Screens everywhere and no golf ball in sight. Airport delay - second division Spanish footy and BBC text commentary it is.

Christine Wilson: Last day of my holiday and I am a golf widow...

Spieth into the third with a wedge... safe as houses. Rose has 130 yards left... just about gets away with it, clinging onto the side of the cliff at the front. Monster eagle for Dustin at six, he moves to seven under. Here's Aimee Lewis for a while...

Mickelson on tee at the 234-yard fourth, going with five iron, and he's into the heart but has a slippery putt coming back. Poulter is hitting some serious irons today, here's another heat-seeker into seven. Defending champion Bubba has a two-footer for eagle at 13... just about blows on it and in it goes, he gets back to +2.

... McIlroy has an eight-footer for birdie at four but he's let another chance go - the world number one's charge just hasn't got going. Mickelson for par at three and he blades it in to stay five off the lead. Spieth and Rose drill irons down the third...

Spieth leads by three...

-17 Spieth (US) 2

-14 Rose (Eng) 2

-12 Mickelson (US) 2

-9 Hoffman (US) 2

-6 D. Johnson (US) 5, Streelman (US) 4, McIlroy (NI) 3, Woods (US) 3

Selected others: -5 Garcia (Spa) 9, Poulter (Eng) 6; -3 Fowler (US) 12

The hushed murmurs after Spieth missed that birdie putt at two said everything - murmurs that were accompanied by raised eyebrows and pursed lips and sharp sideways looks. Part of Spieth's job is to somehow block those murmurs out. Woods makes bogey at four, drops to five under, Rory has a birdie putt...

That's a bit fruity from Rose at two, much work to do to make birdie. Mickelson from a bunker at three... phew, just about clambered out but he's left himself a nasty par putt. Poulter jabs in his par putt at six to stay five under, Rose squeezes in his five-footer at two to start birdie-birdie. Spieth, meanwhile, has missed his slippery four-footer for birdie - the gap down to three shots...

Spieth going with putter from just off the green at two. He's taken an age over this one, walking to and fro like somebody trying to pluck up the courage to knock on a loved one's front door for the first time. It's good enough when he eventually decides to hit it. McIlroy with a dreamy tee shot at three, parachuting in from miles high.

"I think it's been set up for good scoring today. There's always some difficult pins but some of the traditional difficult pins have been softened a bit. That being said, there's so much pressure on these guys."

TomAlexDodd:, external Jordan Spieth, 21. Leads The Masters by 4. Me, 22. German degree at University. Life isn't fair sometimes.

We feel your pain. Apparently Spieth is renting two houses this week. Sigh...

Alan Potter:, external Love The Masters tradition of asking the players "are you ready to play a little golf?" On the first tee.

McIlroy for par at three, that's a great save from about 15 feet. Fowler with a peach off the tee at 12, all over the flag. Tiger for birdie at three... just short of pace, he stays six under. Mickelson, like Woods, finds sand off the third tee, although he's got a horror lie.

Only a par for Hoffman at two, he remains -2. Here's Spieth on the second, going with fairway wood... 280 yards left, absolutely creams it, although it just bobbles over the back. Rose also with five wood, gets a little bit of a skip on, he's got a longun for eagle. Double for defending champion Bubba on 12...
