American Zach Johnson cards 69 for one over and when Tiger Woods fails to make two on the last he is crowned the winner of the 2007 Masters at Augusta.
Johnson was a member of the US Ryder Cup team at the K Club
Woods ends two back after a (72) along with Retief Goosen (69) and Rory Sabbatini (69) with Justin Rose (73) on four over after a double on the 17th.
Jerry Kelly (70) is also four over, with Stuart Appleby (75) and Padraig Harrington (73) five over.
But defending champion Phil Mickelson finishes +11.

2350: There it is folks, Zach Johnson is the Masters champion. Thanks for reading this week. See you again at US Open time (14-17 June) for more golf text commentary on the BBC Sport website.
2345: Tiger Woods fails to hole his second to 18 and Zach Johnson is the Masters champion. Woods pars for 72 and three over, and overnight leader Stuart Appleby takes 75 for five over.
2338: Justin Rose ends with a 73 for four over and playing partner Padraig Harrington cards 73 for five over.
2334: Turns out a chap called Michael backed Zach Johnson each-way at 200-1 before the tournament. He asks whether he can crack open the champagne now. I'd dive in a bath of it if I was you.
2332:Tiger Woods splashes his bunker shot to a couple of feet and makes the putt for par, meaning he will need a two up the last to prevent Zach Johnson winning the Masters.
2325: Tiger Woods's approach to 17 is dead on line but catches the front bunker. "What the hell just happened there," he cries, possibly to caddie Steve Williams. "It was dead down wind."
2320: Justin Rose's difficult chip from the left fringe on 17 runs through the green. He chips back on to a couple of feet but misses the putt for a double bogey and slides to four over.
Playing partner Padraig Harrington makes birdie to sneak to five over.
2315: Tiger Woods just pushes his eight footer right on the 16th to miss out on a golden birdie opportunity. He stays three over, two adrift of Zach Johnson.
Justin Rose is in trouble on 17 with an errant drive and wayward second.
2311: Zach Johnson conjures up a magic chip after finding the right fringe on 18 to make a tap-in par and card 69 for one over.
2309: Justin Rose pushes his drive into the right trees on 17.
2305: Justin Rose birdies the 16th to inch to two over, just one off the lead.
2303: Retief Goosen ends with a 69 for three over and will perhaps contemplate what might have been.
On 15, Tiger Woods escapes with a par after finding the water to stay three over, just two back.
2259: Zach Johnson shaves the hole with his six- foot par putt on 17 to see his lead reduced to two shots.
2255: Justin Rose fires to four feet on the short 16th. Playing partner Padraig Harrington blasts his through the back.
2253: Tiger Woods pumps his second shot into the water on 15 to blow his challenge.
2250: Justin Rose birdies 15 to edge to three over and a tie for second.
2247: We have a new clubhouse leader. South African Rory Sabbatini birdies the last for the first 69 of the day and three over. Playing partner Phil Mickelson takes 77 for 11 over.
2244: Padraig Harrington finds the water yet again in front of the 15th green. Zach Johnson holes his 10ft putt for birdie on 16 to take a three-shot lead.
2240: Luke Donald pars the last for 73 and seven over.
2236: American Jerry Kelly sets the clubhouse lead on four over. Retief Goosen makes a crucial par save on 16 to stay three over.
2235: Andrew Chambers asks what is the highest number of players in a play-off, and what happens if there are more than four, do they play in two groups?
At Augusta there's been 13 play-offs since 1935 but never any more than three players in it.
2229: Tiger Woods holes his eagle putt on 13 to climb back to three over and a share of second.
Justin Rose holes another clutch par putt on 14 to stay four over.
2224: Tiger Woods pulls off possibly the shot of the week. After launching a monster drive down the long 13th, he takes the green on with the second and watches as the ball lands in the middle and trickles down to about three feet from the pin.
2221: Padraig Harrington drains a 15 footer for eagle on 13 to climb to four over.
2218: Rory Sabbatini drives through the back of the short 16th and fails to get up and down to slip to four over.
Zach Johnson gets to one under with a birdie on 14 to lead by two.
2213: Luke Donald putts with his shadow on 16 but shaves the hole for par. Stuart Appleby slips back with a watery double bogey on 12 and partner Tiger Woods makes par from four feet.
2210: Vijay Singh ends with 73 for eight over. Luke Donald drives to three feet on 16.
2205: Co-leader Stuart Appleby catches the water in front of the short 12th. Partner Tiger Woods backs off the first time but finds the heart of the green.
2204: Padraig Harrington holes a good one on 12 for a birdie and six over. Luke Donald birdies 15 to inch back to seven over.
2159: Justin Rose is showing tremendous mettle and fight and holes a crucial 10 footer for par on 12.
2155: Rory Sabbatini was in trouble off the tee on 14 and does well to escape with a bogey.
2151: Padraig Harrington agonises as his par putt on 11 slides past for seven over.
Tiger Woods bends his club almost to right angles on a tree as he plays out of the pine cones on 11. He'll be allowed to replace it as he did it in the act of playing a shot.
2147: Luke Donald makes a second straight bogey to drop to eight over, while Jerry Kelly has an eagle chance on 15 but makes birdie to get to four over.
Justin Rose holes a long one on 11 to inch back to four over.
2143: Tiger Woods makes a complete hash of a short putt on the 10th to slide to five over. Paul Casey ends with two bogeys for a 71 and seven over.
2139: Retief Goosen leaves his long first putt short on the par-three 12th and misses the second to rejoin the pack.
2136: Sweden's world number six Henrik Stenson cards a round of 72 for nine over.
2130: Luke Donald finds the water on 13 and makes bogey to slip to seven over.
2127: Tiger Woods goes out in 37 and is just one stroke behind. He's never won a major when trailing going into the final round. Can he break that habit?
2119: Ian Poulter, who is a far better competitor than he is given credit for, takes the clubhouse lead with around of 70 for eight over.
2115: Stuart Appleby misses a short putt to tie for the lead on eight. More excitingly, Paul Casey nails a cracker for birdie on 16. Aiming at more or less right angles the ball arched round and into the hole to go five over, just three back.
2112: Justin Rose drains a big one on nine to inch to five over, only three back and still in with a great chance.
2108: In case you're interested, Retief Goosen's caddie is apparently Colin Byrne, a low handicap player in his own right and a member of Royal Dublin, home club of Irish Ryder Cup legend Christy O'Connor Sr. That's what Ray Crawford of Dublin's Clontarf Golf Club says anyway.
2102: Justin Rose nudges back to six over with a birdie on eight. He's three over for the day. Luke Donald makes a good par putt on 11 to stay six over.
"I am not getting too excited but do you remember an hour ago I said about Retief Goosen at 16/1 without Tiger. My £200 on him is looking a bit good now. I have no nails and no beer either. It could be a good time to start smoking again."
Andrew "Big Chief" Dearden
2100: It's just occurred to me that it's a bit unfair on Masters champions that they wear the same Green Jacket as the Augusta members. They should have some sort of differentiation to denote having actually won the tournament, rather than just being rich. Maybe gold epaulettes.
2057: Jose Maria Olazabal, the last European Masters winner in 1999, signs off with a 77 for 16 over.
"It's been a survival week," he tells BBC golf commentator Hazel Irvine. "It's been the toughest Masters I've played."
2053: Leader Retief Goosen goes out in 32 but misses a shortish putt on nine to go three over and to lead by two.
"Whilst watching the Masters with my four-year old step-son I have just tried to explain why the scoring has been so high. He was not convinced as he has just completed his play station Augusta National course in 17 under. Your help appreciated ASAP !!"
Tony Cross, Kent
2049: I defy anybody to say this isn't one of the most exciting Masters for a long time. Anyone know who's going to win yet? Thought not.
2044: Remember that commentary curse I was talking about? Peter Alliss has just said on TV that Tiger Woods looks "slightly weary". Well, that's blown that then.
Woods does bogey the sixth, mind you, to slip to four over.
2041: No sooner does Retief Goosen join Rory Sabbatini in the lead than his countryman bogeys nine to slip back.
2037: Paul Casey finds the water on 13, Ian Poulter birdies 15 to go eight over, and Retief Goosen birdies eight to join fellow South African Rory Sabbatini in the lead on two over.
2031: Luke Donald's wheels are coming off. He has watched two chips up onto the ninth green roll back to his feet en route to a triple bogey to slide to seven over.
2027: South African Rory Sabbatini holes out from at least 50ft on the seventh, borrowing miles before watching the ball snake back round and die into the cup.
He takes the lead on his own at three over but Luke Donald sees his approach to nine trickle off the front and his pitch back on does the same thing.
2021: Retief Goosen pulls off a wonder shot from the pine needles on seven. He hits it to four feet and drains the birdie putt to join Tiger Woods in the lead on three over.
Two-time champion Jose Maria Olazabal, the last European to win the Masters in 1999, cards 77 for 16 over.
2015: Luke Donald pitches in for eagle on eight to climb to four over and second place.
2005: Zach Johnson's bogey on five hands Tiger Woods the outright lead just before he tees off on the fourth. That didn't take long did it.
1955: Justin Rose double bogeys the third after chipping through the green to slump to six over. Tiger Woods birdies two to join Zach Johnson in the lead at three under.
1944: It's going to be a crazy day at Augusta! No sooner was there a six-way tie for the lead virtually the minute Woods and Appleby completed the first, than Zach Johnson goes clear with a birdie at the third.
1934: OK folks, strap yourself in, it's game on. Overnight leader Stuart Appleby double bogeys the first to slide to four over. Tiger Woods bogeys the same hole also for four over.
1929: Retief Goosen, who made the cut right on the number at eight over, birdies the third to edge to four over, just two off the lead.
But Welsh debutant Bradley Dredge opens with three bogeys slide to eight over.
1924: Justin Rose has struggled with the first all week and double bogeys it this time to plummet to five over. Padraig Harrington bogeys the first and is also now in the growing group on five over.
1917: Our leaders Stuart Appleby and Tiger Woods tee off down the first. Up ahead, Rory Sabbatini is on the move with birdies at two and three for just four over.
1910: Zach Johnson and Vaughn Taylor bogey the first to slip to five over, while Rory Sabbatini birdies the second to get to five over and David Toms birdies three for five over.
1905: Paul Casey stumbles at the fifth to slip to nine over. But generally the course seems to be playing ever so slightly easier today - a bit softer perhaps - so there could be a couple of scores in the 60s.
1857: Sandy Lyle bogeys the last but is in with a round of 71. That's great work and could be in the mix for round of the day. Shame he's 15 over.
Ian Poulter birdies eight to be two under for the round, eight over for the tournament. But Bradley Dredge bogeys the first to slip to six over.
"Which player (judging from the picture on the web page) has found a new way to try to beat Tiger? Burying him up to his nose in the Augusta turf is almost certainly contrary to the Rules of Golf ? but in any case, I reckon it would be pointless as I bet he would still win anyway."
Tim Haveron Jones, Holyport
1850: Wow! Phil Mickelson blows it. The defending champion takes a triple-bogey seven at the first to wipe out his chances. He's now nine over.
Going in the right direction is Luke Donald who picks up a shot on the first to get to five over, while Sandy Lyle birdies 17 to be two under for the day and 14 over for the tournament.
1838: More Champions Dinner chat. "By the time Monty wins a major (Masters in 2301), we won't need a Champions Dinner as by that time we will just have some sort of chip that quenches hunger."
Michael in Clydebank
Presumably not a crinkle-cut chip though.
1833: Sandy Lyle fans are in raptures (I know, I'm one of them). The Scot is one under through 16 and potentially on track for the low round of the day. Sadly, Sandy is 15 over for the tournament after rounds of 79, 73, 80.
Meanwhile, Vijay Singh birdies the second to edge to six over, just four back, and Mike Weir holes his bunker shot from the back of the 11th for par to stay 11 over.
1826: Confession time. Vince from Curacao points out the groupings are decided on your score that day, not when you finished. And having checked it out, we agree with him. Thanks Vince.
Meanwhile, Roger writes on the subject of the Champions Dinner: "If there is a British winner, surely it will be one of those M&S ready meals you bung in the microwave."
1820: Lee Westwood starts with a bogey to go to nine over, Ian Poulter birdies the sixth to go nine over, Paul Casey is still eight over after three straight pars and Vijay Singh stays seven over after a par at the first.
Tim Clark, meanwhile, last year's runner-up, drops a shot at the first to slip back to seven over following his 80 yesterday.
And poor old David Howell, the nicest man in golf, has his first three-putt of the week to drop to16 over after 11.
1815: A few of you have emailed to ask why Tiger Woods gets to play in the last group and not Justin Rose, despite being tied on the same score. Is this Woods getting preferential treatment? Well, no, it's because he finished first.
On another theme, here's a good one from Andrew Dearden.
What would you have for your Champions Dinner if you won the Masters? He reckons next year it will be pie, chips, peas and gravy. I've never had Tiger down as a pie man.
1803: I was about to write that nobody has gone on a real charge yet, but then I noticed Mark Calcavecchia.
"Calc" is three under through two after starting birdie, eagle to climb to six over. That's just four off the lead my friends. And this is a former Open champion so he's got the nerve.
1800: He said yes! Great news, Andy and Francis have been reunited (see below). I feel a bit like Cilla.
1752: Firstly, sorry to everyone for saying live Amen Corner starts at 1830 BST. It's just gone live NOW so get on it (UK broadband users only with Real Player). Go to the top of this story, or the golf index, top left. It's working fine so you should be all right. Apologies if you can't access it.
1748: Back at Augusta, former Open champ Mark Calcavecchia is the new on-course leader with a birdie at the first for eight over.
And England's Paul Casey begins with a par to stay eight over after slumping to that 77 yesterday following a triple-bogey eight at the 15th which derailed him.
1741: I know the Beeb is a public service broadcaster but I didn't think that extended to a friends reunited-type service...until now.
Andy Hallberry, of the sumptuous pad with 17 bedrooms in the Hollywood hills fame (see below), would like to know if he can have his old mate Francis Jago's address. Well Francis, can he? Privately, of course.
Meanwhile, that astute golf observer Jason Linsdell has been on the email. He says, "I can't believe how people are ignoring Phil Mickelson's claims.
"He has won two of the last three Masters, and finished in the top 10 in each of the last eight years.
"Since 1995 he's finished T7, 3, Cut, T12, T6, T7, 3, 3, 3, 1, 10, 1. And being four shots off the lead, he certainly has a big chance."
1734: US Open champion Geoff Ogilvy is making the most significant early move with birdies at two and three. Trouble is, he's nine over after that nightmare 81 yesterday. Aussie Ogilvy is a good mate of Justin Rose and Paul Casey by the way. Apropos of nothing.
1733: That's it, that's the final straw, it's official. There is an online curse and we must live with it. Literally the second I was about to write, "I hope I don't win £18m on the lottery" (as a way of getting it to happen, you see) Nick Dawson tells me it doesn't work like that.
1723: Andy Hallbery (see below) must be chuckling into his bloody mary. "Tell my mate Andy, who I have known for 15 years, to stop boasting!" says Francis Jago.
"I am watching the cricket in Antigua and preying that Tiger doesn't win yet another major!"
And before we go back to the golf, a quick round-up of some emails:
"Big Chief" Andrew Rearden says Retief Goosen at 16/1 without Tiger Woods is the bet of the day. "He will post a number around +4 and that will be good enough."
Michael in Clydebank says, "I found it amazing yesterday the threat Tiger must pose to the field. They bottled it and came down to meet him rather than him forcing his way through. Tiger to win -1/-2.
Will Gallimore says, "I do believe a certain Mr Appleby is being over-looked by all those predictors out there. Leader by one, been there and won tournaments before (unlike Rose).
"I'm backing a 70 from Apples, and a winning score of level par... (and a tidy sum thanks to having taken advantage of the 100/1 price plonked on him before the tournament)."
1715: There's definitely something in this online curse thing I was talking about before. Because just as I write Rollins and Cink are the on-course leaders, Geoff Ogilvy and Tom Pernice Jr overtake them, climbing to nine over.
Let's try something else: "Justin Rose won't beat Tiger Woods in a play-off." Now just settle back and watch that little baby unfold.
1710: Well, Richard, it was maybe a sign then. But now Americans John Rollins and Stewart Cink are under par, too. In fact, they're the joint "on-course" leaders at 10 over.
This made me laugh. "Look, could you ask that Andy Hallberry (see below) to turn his TV down? I live in the appartment next door and I'm trying to write an essay."
1700: There's only three players under par for the day at Augusta so far - they are Angel Cabrera (-2), Shingo Katayama (-1) and Sandy Lyle (-1). Everyone else is either treading water or going backwards. Does this suggest another brutal day? Could the winning score actually go backwards from two over?
"It's a sign, it's a sign...all the players currently playing sub-par golf today are non-US!!"
Richard Kelman, "Lost in Romania".
1650: Andy Hallbery has kindly written in from America. He says: "To all the youngsters skiving on their essays today, here's a life lesson.
"I did exactly the same in my youth, and am now sitting on my sunny Californian balcony facing the sea, with the golf on TV, and the cricket on my computer. Bloody Mary on the way. Life's a bitch (not)..."
Sounds good my friend, but the rest of us stuck in the UK have something much better to look forward to.
LIVE Amen Corner coverage on this website (golf index, top left) resumes at 1830 BST for broadband users with Real Player.
1643: Mike Weir is struck down by the curse of the online commentary. No sooner do I tell the world he's having a lovely time at Augusta than he goes and bogeys the third to drop back to level. Now let's see if this will work...Tiger Woods has had a tremendous lunch and will beat Justin Rose in a play-off. (Do you see what I've done there?)
1635: We have a new on-course leader. It's Canadian lefty Mike Weir, the 2003 winner, who has edged to 10 over with a birdie on the second.
For what it's worth in the "predict a winner" game, I'm going to plump for a bucking of the trend. The winning score will be two over and the owner of a shiny new green jacket will be...Mr Justin Rose.
Dave in Edinburgh, meanwhile, makes a good point. "Why is no one talking about Jim Furyk?" he says. "No one in the discussion boards is talking about the guy who was second on the PGA Tour money list last year.
"He hasn't even been on the highlights yet he is tied 8th, posted a 71 on Friday and has a great chance. Or is my judgment coloured by the amount of dosh I have riding on him at various prices from 25/1 to 80/1?"
1628: Disaster strikes for Sandy Lyle fans hoping for the fairytale to end all fairytales. The big man makes bogeys on six and seven to undo all the good work of earlier (three birdies in five holes).
Everyone's favourite 1988 Masters champion is back to 15 over. Still, there's always next year.
1620: Thank you James, marvellous work. In fact, nice commenting. Now then, on course David Howell is the "leader" having strolled through his first two holes in level par to stay 11 over.
1613: Right, that's my brief stint over, I've been in work since six and my colleagues tell me the sun has got his hat on.
Enjoy the rest of the tournament and I'll leave you with my tip, and this will really put the big cat among the pigeons.
Yes, I'm tipping Tiger, and who can blame me?
1610: Mark emails from Lancaster University to explain just where his student loan is going.
He writes: "Got a few long shots on for today that I'm praying will come in to help pay off the student debts! My main hope is Justin (£10 at 130/1) - think he's really come a long way since last year - and Sabbatini (£2 at 560/1) so can't wait until they tee-off, and although the general feeling is for Woods to come through I've got my suspicions he won't this time! Currently in the library working, but will sneak back to watch the Masters, obviously got to get my priorities straight!
1608: Sandy Lyle has birdied three of the first five holes while David Howell, so impressive before his disastrous third round, has opened up with a par.
1603: Prince Harry is at the England v Australia World Cup cricket game in Antigua - wonder if uncle Andrew, a former captain of the R&A, is in Augusta?
1559: Of the 16 players out on the course, four are sub-par, four are level and eight are already over par, with no-one having played more than six holes.
1555: Simon from Fife emails in with his prospective betting coups.
He writes: "I've got a few bets on for today, managed to get Appleby at 25/1 before his round yesterday so could be a tidy profit if he manages to resist the Tiger. Also had Bradley Dredge on E/W before the tournament at a massive 500/1 so it could earn me some Grand National betting money....Simon at 16/1 if anyone wants to know!"
1550: Fred Couples is the fourth former champion to tee off on Sunday. He starts with a regulation four.
David Howell is just about to tee off - his 82 on Saturday saw him plummet out of contention after he started the third round just three shots off the lead.
1544: Those winning score guesses - in true BBC fashion the prize is a virtual Blankety Blank chequebook and pen - you'll have to remind Rob and Matt later on.
Ben Pocock - Woods to win with 2 under..........everyone else around him to collapse as per usual.
Alistair Goodall - If Tiger cuts out his bad holes, then maybe level or -1. If someone else wins it then +2 will be good.
John in Arundel - I agree with Tony it will be tough I think 2 over will win. I think it will come down to putting and like the look of Harrington. Come on Padraig!
Rocket Ron - I think Woods will win it with -5. It will play a lot better today. So sit back and watch the master.
Kevin in Leeds - Winning Score? +4... Winner if not the Tiger, our English Rose but only if he stops missing short putts on the right... anyone else notice this? Struggling to get putter through on the fast greens... back nine pressure won't exactly help!
And finally for now, James Henderson has come over all Nostradamus - Big Phil will score an amazing 68 to get to +2 for the tournament. Tiger will be on one over for the day until the 18th when he'll get an eagle to take him to +2 for the tournament too. Everyone else will score in the 80s. Tiger and Phil will go into a playoff which will last for 7 holes, and Tiger will win with a 120 ft putt birdie after Phil makes par.
1535: Sandy Lyle's birdied the second while fellow former champion Fuzzy Zoeller is level through the first two.
1528: Alex emails from Sandwich in Kent - now there's a place that knows its golf.
He writes: "Padraig said on Friday whilst being interviewed by Hazel Irvine he felt +1 or +2 would win. How right it looks - that's my score for the winner, don't you agree?"
Interesting one that - it seems like a good shout to me but did he know he know the course was going to play so difficult on Saturday?
Padraig's saving up to buy a plane by the way.
Last year Phil Mickelson's victory brought him the little matter of $1,260,000 (£641,069), so topping the leaderboard on Sunday night would probably buy the Irishman at least a wing.
1521: When it comes to betting I'm about as well informed as a nun attending a male life drawing class, but Michael looks as though he found some value on Tiger on Friday.
Michael writes: "Here's a couple of bets I'm waiting on today hopefully!
"Zach Johnson backed pre-tournament e/w at 200/1, Padraig Harrington backed last night to win @ 20/1, Tiger Woods backed on Fri (when he was 8 behind) to win @ 7/1, Lee Westwood backed e/w today at 250/1!!
"Did you notice that Westwood is ranked 1st for putting at 1.43 per green going into today's final round? That's some price for a guy only 6 behind (I hope).
"Cheers and keep up the good work!"
Cheers to you too Michael, we'll join you at the bar if any of those come in.
1512: Japan's Shingo Katayama starts with a double bogey but at least Crenshaw is going in the right direction as he birdies the second.
1507: Chris the expat Brit from Vancouver emailed in the early hours to say the tournament never gets going until the back nine on Sunday.
We all know Tiger will be up there come the crunch, the question is, will there be anyone there with him?
1503: Tony McNee emails in from Lancashire to ask: "Any idea on the winning score? I'm going for 5 over par, never thought a Masters would play tougher than a US Open."
Good question Tony - anyone care to hazard a guess?
1458: Is this a sign things are going to be easier today - Billy Mayfair and Trevor Immelman have both parred the first, making it three out of the first four not to drop a shot.
1449: They're off and running at Augusta for the fourth and final round of the 2007 Masters.
Unlike Saturday, when it took until the fifth pair for someone to avoid dropping a shot on the first hole, the notorious Tea Olive, Crenshaw opens up with a safe par, although Oberholser does drop a shot to slip back to 19 over.
1430: Afternoon all, while the players out early on Sunday are also-rans this time round, that has not always been the case as there are three former Masters champions in action in the first four pairs.
Two-time winner Ben Crenshaw was champion in 1984 and 1995, Scotland's Sandy Lyle won it in 1988 and Fuzzy Zoeller claimed the coveted green jacket on his maiden appearance in 1979.
The final round of the 2007 Masters starts at 1435 BST (2.35pm) local time, with two-time Masters champion and American journeyman Arron Oberholser the first pair on the tee.
Golf obsessives can ignore the next bit.
The players at the business end of the tournament will not get started until about four hours later as they go out in reverse order, with the leaders last, general sports fans.
