Tiger Woods wins his 13th major title after withstanding pressure from Ernie Els and Woody Austin in the final round of the USPGA Championship.
Woods, who moves one closer to Jack Nicklaus's record of 18 majors, won by two shots at Southern Hills.
The world number one had seen his five shot lead shrink to just one, but a superb birdie at the 15th ensured he defended the title.
Earlier, England's Simon Dyson fired a superb 64 to power to level par.

2354: That's it - Tiger makes the simple putt to win his 13th major championship.
He hugs caddie Steve Williams as the crowd go bananas.
2352: Tiger Woods's first attempt at the putt goes about two feet past the hole. I reckon he might win this.
2347: Tiger can savour every step of his walk to the green as his second shot comes to a halt in the middle of the green.
He's pointing out people in the crowd and flashing that famous smile as he gets a hero's welcome.
2344: Tiger Woods fires a lovely tee shot right down the middle off the 18th tee.
2343: "I wonder if there's one final twist to come on this final hole - it's a real tester."
BBC Radio 5Live golf correspondent Iain Carter
2341: Woody Austin misses his long-range birdie putt at the last, and he now needs Tiger Woods to make a right old mess of the last which you can't really see happening. He makes his par to finish on six under, and takes his deserved applause from the gallery.
2340: A par at 17 for Tiger Woods, and he can almost touch his 13th major title.
2339: Woody Austin is angry with himself after his drive at the last goes astray. He knows he has to give it everything, but the direction is not right.
2333: Ernie Els knocks in a short putt for a round of 66. He can be proud of his efforts, even though he ultimately came up just short - this was the old Ernie Els, no doubt.
2333: As expected, Tiger Woods makes his par at the 16th.
2329: Well done Woody Austin. He holds his nerve at the 17th with a far from easy par putt to keep his hopes just about alive.
2338: Tiger Woods is assured of a par at the 16th. He really has responded in the best possible way to the charges from Ernie Els and Woody Austin.
2326: Woody Austin goes into the bunker in front of the green at the par-four 17th, but he still has a chance.
2322: Ernie Els could be out of the running now after his attempted birdie putt at the 17th stays out. Even if it doesn't come off for him, it's been an oustanding effort from the South African.
2320: If you're one for omens, then you might want to know that neither Woody Austin nor Ernie Els has birdied either the 17th or 18th in the previous three rounds. To be fair, neither has Tiger.
2319: Woody Austin holds his nerve on a par putt at the 16th, but he is running out of holes to find the birdies he so desperately needs.
2314: You have to take your hat off to Tiger Woods. After all that has gone on in the last 15 minutes or so, the defending champion calmly rolls in a birdie at the 15th to go two shots clear again.
2308: Ernie Els does not manage to rescue his par at the 16th and has to take a bogey. Could that be the end of his chances?
2303: Woody Austin probably didn't realise he was putting for a share of the lead, and his effort at the 15th goes just to the left of the hole.
2301: Goodness gracious me. Tiger Woods's par putt lips out and his lead is down to just one hole.
2259: Some signs of tension from Tiger Woods as his first attempt at a putt at the 14th is pushed several feet past the hole. He needs to make the four or five footer for par.
At the 15th, Woody Austin has given himself a good chance of a birdie.
2253: Ernie Els goes well left with his tee shot at the 16th; Tiger Woods, meanwhile, fires a decent effort off the tee at the 14th.
The chat on the course is that Woods may have done himself a mischief with his exuberant celebrations after his birdie at the eighth. We shall see.
2249: Tiger Woods does indeed get his par at the 13th, but there are suggestions he may be struggling slightly with an injury.
Further up the course, Ernie Els and Woody Austin also make their pars, so it's as you were as we get to crunch time on the back nine.
2246: On the par-five 13th, Tiger overhits his approach to the green by some distance, but a beautiful sandwedge out of the bunker ends inches past the hole. He should be fine for a par here.
2240: It's game on in Tulsa. Ernie Els and Woody Austin are like a tag team ganging up on Tiger Woods as they both make birdies to close to within two shots.
Which idiot said it was all done and dusted earlier? That was me... sorry about that.
2232: Ernie Els is battling away, and he gets another birdie at the 13th - after narrowly missng with an eagle putt - to go back to five under. This is getting more exciting by the minute.
2223: Who would have thunk it? Back-to-back birdies for Woody Austin as he gets a rapturous reception after holing at the 12th.
He is playing like a man possessed, and appeals for more noise from the gallery. Contrary to his reputation as a nervy character, Austin is relishing the grand stage.
2215: The pressure of trying to chase Tiger Woods is getting to Ernie Els. The South African leaves his par putt short at the 12th and he falls to four under.
2209: Fair play to Woody Austin. He holes a birdie putt at the 11th to return to four under.
2206: South Africa's Trevor Immelman birdies the 15th to move to one under for the tournament. There are just five golfers in red figures.
2201: The look on Ernie Els's face says it all as he misses with his birdie putt at the 11th. He really could have done with that.
2156: There's still some life left in this championship. Tiger Woods bogeys the ninth to offer a chink of light to Ernie Els, who is in with a shout of a birdie at the 11th.
Stephen Ames also drops a shot at the ninth, and we can probably cross him off the list of realistic contenders now.
2154: John Daly brings his week to a close with a round of 73, and a score of six over for the tournament. A slightly disappointing end to what had been a very promising start.
2149: Ernie Els certainly hasn't given this up as he birdies the 10th. You've got to admire his fighting spirit, and he gets the reward for an aggressive drive off the tee.
2144: Has there ever been a better front runner than Tiger Woods? He deals a body shot to the hopes of his rivals with a simply awesome birdie putt at the eighth.
Woods, who celebrates with the assurance of someone who fully realises the shot's significance, now holds a five-shot lead. This championship - as it has been since the end of Friday's awesome round, in all honesty - is his to lose, make no mistake.
2141: "You get the feeling Tiger Woods is going to coast, unless someone shoots at superb inward nine."
Nick via text
2135: Tiger Woods only knows one way of responding to pressure and that's to fight fire with fire.
He holes a birdie putt at the seventh to go back to four shots ahead.
Ernie Els has a birdie chance at the ninth, but he is a little tentative with his shot and sees it come up short.
2124: This is what we want to see. Ernie Els nails a superb birdie putt at the eighth to become the main challenger to Tiger Woods at four under.
2120: Tiger Woods's birdie putt finishes two inches short, giving him a simple par. Stephen Ames also saves par, but there is very little fluency in his game at the moment.
Over on the seventh green, Woody Austin is going backwards as his suspect putting lets him down again. He drops a shot to move back to three under.
2112: Stephen Ames is falling victim to the curse of playing alongside Tiger Woods as he three-putts for a bogey at the fifth.
Woods, meanwhile, shrugs off a horrible tee shot to make a steady par and keep his momentum going.
2109: Stuart Appleby is putting together a cheeky little three-under round after 13 holes to get to level par.
2100: "Some pressure on the big guy, let's hope we get a cracking finish. I'd love to see someone strike the lead and see his backlash!"

2056: Tiger Woods takes a driver off the tee at the par-five fifth, but things don't go to plan as he misdirects the ball well right of the fairway.
There's a mutter of "Goddamn it" and the thud of a driver being slammed into the ground, which will all be music to the ears of the chasing pack.
2052: Tiger Woods seems impossible to rattle. He strokes in a birdie to restore his three-shot lead, but there's another bogey for Stephen Ames.
2050: Ernie Els is making a genuine charge now. A solid putt at the fifth gives him another birdie, and he moves to within three shots of Tiger Woods
2043: A missed opportunity for Woody Austin as he misjudges a very makeable birdie putt at the fourth. He could have really put the heat on Woods with a birdie there.
2041: A good response from Stephen Ames as he confidently rolls in a 15 foot putt for a birdie at the third, returning to four under. Tiger records another par.
2034: Maybe this is going to be more competitive than we thought. Woody Austin birdies the third to close the gap on Tiger Woods to just two shots.
2027: The brutal second hole claims two more victims with Tiger Woods and Stephen Ames both making bogeys.
Ames is going backwards at a rate of knots with two dropped shots in two holes. Tiger makes a rare mistake, but has not really been punished.
2025: Kevin Sutherland has joined the band of players in red figures thanks to a birdie at the third.
2023: Ernie Els is doing his bit to add some drama as he birdies the third to climb to two under.
2021: Neither Tiger Woods nor Stephen Ames are covering themselves in glory on the second, with Ames hitting a bunker and Tiger having to dobble out onto the fairway after a mistake off the tee.
2013: Stephen Ames looks anguished as he bogeys the first. He pays the price for the bad tee shot, and gets off on the wrong foot to give Tiger Woods - who pars the hole - a four-shot lead.
2008: John Senden gets off to a bad start with an opening-hole bogey, to drop back to one under.
2003: Perennial major tournament underachiever Adam Scott could be in for more disappointment as he bogeys the third.
1959: I wonder if Tiger ever grows tired of shouts of "get in the hole" after every tee shot he ever plays? I certainly do, and I'm not even him.
Tiger's opening tee shot goes a little right, but it's nowhere near as bad as Stephen Ames's which goes miles left. Surely he can't be crumbling already?
1957: Tiger Woods and Stephen Ames stride up to the opening tee, and there's not a lot of chat between the two. To be fair, they're just about to start the final round of a major in the final group.
Although if I was Tiger, I'd be asking Ames if he could turn his lime green shirt down a bit.
1954: Ernie Els and Boo Weekley both salvage a par from the opening hole, despite some mistakes on the way to the green.
1948: Some encouraging words for the chasing pack from Simon Dyson, who has just produced the second best round of the tournament: "The fairways are running well, and the greens not as firm as I thought they would be.
"There's no wind and you can fire it and stop six irons in two or three feet so I can see someone going low."
Dyson also reveals that he drank 20-odd bottles of water in the course of his round, so Stephen Ames should start stocking up.
1941: Not the start that Ernie Els was after as his tee shot off the first lands straight in a bunker on the right. His playing partner Boo Weekley keeps his drive on the fairway.
1935: Adam Scott, some people's idea of someone who could fire the very low score needed to pressurise Tiger Woods, starts off with a par at the first to remain at level.
1932: "I'm on Boo Weekley at 100-1 each way and Adam Scott at 40-1, so I'm praying for a miracle!"

1929: Tiger Woods, wearing his traditional final day colours of red and black, is belting the bejesus of a few balls on the practice range with his driver.
The sweat is pouring down the side of his face, but if there's any golfer in the world with the fitness to withstand the pressure and the conditions, it's Tiger.
1925: "Nice round from Simon Dyson - wouldn't be surprised if even par gave him a top 5 finish."
Kinsang on 606
1923: The Big Easy could do a lot worse than tap up Simon Dyson for a few tips.
Dyson knocks in a lovely birdie putt at the last to bring the curtain down on a round of 64, the second lowest round of the tournament, to come in to level par.
1920: Ernie Els is not giving up, saying he is targeting a score of 63 to put himself in with a shout.
"Who knows? The game of golf is a crazy game," says Els.
"I feel like there's a lot of positives in my game but I've got to eliminate my mistakes.
"I've got to be aggressive, but within myself. I can't take on shots that I don't normally play."
1912: Justin Rose kicks off with two straight pars to stay three over. Simon Dyson is still five under going down the last, which means he needs to drive it 465 yards for a hole-in-one to break the record.
1905: Luke Donald double bogeys the 2nd to slide to five over.
1900: Paul McGinley is having a bit of a 'mare. He double bogeys 16 and drops another shot on 17 to plummet to five over for the round, 11 over for the championship.
First-round leader Graeme Storm bogeys 13 to slide to 10 over overall.
1856: Simon Dyson's got three holes left and is currently five under for the day. Which means if he birdies his way home, he's the new major low-score record holder. Which would be nice.
1851: Oh Monty! The big man was trucking along quite nicely but bogeys 17 and double bogeys 18. Oops. That's a round of 70 to end the tournament eight over.
1849: World number three Phil Mickelson picks up his first birdie at the 17th following 16 straight pars to inch to six over.
1843: The Wild Thing - John Daly - is into his round now and one under for the day through three for two over overall. That's nine behind Tiger Woods. He couldn't, could he? No.
1829: Simon Dyson is still on the birdie trail as he records his sixth at the day. Great stuff from the Englishman, who is now within sight of a below par score for the tournament.
1819: Crowd favourite John Daly gets his round under way with a steady par at the first.
1814: Open champion Padraig Harrington complained of feeling flat after his third round, and he is no more fizzy today as he opens with two bogeys.
1802: Ian Poulter's round gets off to a bad start as he bogeys the first.
1752: Fear not, though Dyson fans. Your man picks up another birdie at the par-three 11th and returns to four under for his round.
1747: Simon Dyson's momentum is stopped as he bogeys the 10th to fall back to three over.
1735: "I think the best chance of someone beating Tiger is a 63 or a 64 from Ernie Els and Tiger only making a 70. And I don't think that is much of a chance."

1723: Two birdies in a row for Lee Westwood - it's been a more positive day for a few British players, with Simon Dyson and Colin Montgomerie also enjoying decent rounds. Unfortunately, it's very much a too little, too late situation.
1708: "I wouldn't write off Stephen Ames yet. Yes, he got ripped apart by Tiger in the WGC Match Play, but that was just one of those freak results.
"Obviously everything is in Woods's favour, but Ames has won the Players' Championship convincingly and is tougher than most people think. Perhaps all this 'Tiger's got it in the bag' talk will produce a closer result than people think..... "
Kinsang on 606
1705: Colin Montgomerie is enjoying his best start to a round of the tournament, with a fourth birdie of the round taking him to three over.
1656: Maybe Simon Dyson is the man for the job? He makes another birdie at the sixth - his fourth of the round.
OK, let's stop being facetious, he's still on two over, but it's one hell of a start to his round.
1653: Lee Westwood has steadied the ship after day three's bogey-fest, with the 34-year-old making par on every single hole with seven left to play.
1645: Afternoon all, I'd love to say that I'm rubbing my hands in anticipation of a thrilling final day of the last major of the season - but I'm not.
Hopefully someone can prove me massively wrong by emerging from the field to put Tiger Woods under some kind of pressure.
But the fact that Tiger's closest challenger - Canada's Stephen Ames - lost 9&8 to him in the WGC Match Play last year does not bode well.
1638: Dyson birdies the fourth - he's now three over. Monty's grabbed a birdie at the par-four seventh.
1632: "So far this has been the most disappointing major in a long long time."
MA via 606
1628: Casey pops in a birdie at the fourth. Benzel drops his sixth shot in five holes to go 20 over. Dyson pars the third.
1618: Dyson is motoring - or should that be hoovering? - up the leaderboard after beginning with two consecutive birdies. He's four over now.
1613: Now's it the second bogey in a row for Casey, too - his five at the third puts him alongside McGinley on eight over. Benzel's nightmare is continuing - a double-bogey six at the 10th is followed by a dropped shot at the 11th. He's now languishing at 19 over, six over for the day so far.
1605: McGinley, who had a 66 in his second round, has dropped another shot at the second and slips to eight over. Include his six at the 18th yesterday and he's shipped four shots in his last three holes.
1556: OK, it's hardly a charge but Monty has nabbed a birdie at the fourth, his first of the week at that hole. Casey drops a shot at the second but it's a good start for Simon Dyson, whose birdie at the first takes him to five over.
1540: England's Paul Casey makes par at the first. Ireland's Paul McGinley drops a shot there.
1516: Nice, confident start from Colin Montgomerie - back-to-back pars to open his round, matched by "Lefty" Mickelson, while Westwood is still even after three. Not so good from our man Ryan Benzel, whose dropped four shots since his opening birdie. He's out there on his own, like the bloke whose nipped out before his Sunday roast to clout a few seven irons up and down the local rec.
1458: Solid par from England's Lee Westwood at the first - that will settle him after three successive opening dropped shots yesterday - while Brian Bateman's gone birdie-birdie at three and four to climb five. Monty's out next with 2005 winner Phil Mickelson, who starts an incredible 14 shots behind Tiger.
1449: Course weather is "fair" - that's Oklahoma talk for 81 degrees F. Apparently, the wind, if it arrives today, will be from the north, but at the moment there's zilch.
1447: Come on chasing pack, make it a bit exciting!!!! (Where's Greg Norman with his last day charge?)
Kinsang on 606
1432: Frank Lickliter II, who sounds like he should be a tough-talking flight controller at NASA mission control, or perhaps a precinct captain in some 70s cop thriller backed with a funky Lalo Schifrin soundtrack, has popped one in for a birdie and leaps three places up the board.
1421: Ho hum, Benzel's back to level par for the round after dropping one at the second. The next pairing out - Americans Brian Bateman and Mike Small - both par the 464-yard first but it's a slow start for Dane Thomas Bjorn, who bogeys his opener and drops to 11 over.
1400: Great news from the first green. American Ryan Benzel has birdied the first and is off to a flyer. Update on this lad - he won the 2005 Pacific Northwest PGA Rosauers Open and is a bit of a grafter by all accounts.
And here's top punditry from Ernie Els, the only man with a major title within eight strokes of Woods at the start of play today. If Tigers wins, it'll be his fourth PGA crown to go with four Masters, two US Opens and three Open Championships. Ernie says: "If I was a fan on the couch I would be putting my house on it." Cheers Ern.
1350: Day four and Tiger's on the prowl. Three shots clear and ominously poised to land another 'big four' trophy.
The American is 12 and 12 in winning majors when leading after three rounds and looks in the mood for a 13th major title - which, in real money, is five shy of Jack Nicklaus' all-time record.
Woods, is due to tee off at around 2000 BST but the action is due to get under way at any moment when Ryan Benzel tees off. Born Seattle, Washington. Er, that's it so far on him. Made the cut at +13.
First Brit out is Lee Westwood at 1440, along with Swede Niclas Fasth.
1345: "There will be no Sergio style flop this major, I predict a runaway victory of 5 plus shots. Only three more years until he eclipses Jack Nicklaus' record."
