Adam Scott still cruising on level par after a fifth successive par on the back nine. Two holes left for the Aussie.
It's a missed putt for Kapur and he secures a par to stay at four under.
An hour after snapping his six iron, Charl Schwartzel finds the sand and you fear for another one of his clubs...the South African keeps his cool (just), jumps into the bunker and chips it straight in to finish his round of 75.
Quite a few tipping Rickie Fowler - before today that is - but he's on +7 after 16. The beautiful one has had better days.
A varied day for Luke Donald. Not in a good way. Five bogeys, two double bogeys and he's +8 with one to play. A birdie on the 17th though will give him a mini lift.
Luke Donald just misses out on par on the final hole and ends with 80 and a score of 9+. And it's head in the hands time for Adam Scott as he taps in for a bogey and wraps up with a 71.
Dazzling stuff from Tiger Woods on the par five 17th as he lets rip and his second shot bundles along the fairway before curling around on the green to get within 40 feet of the pin. Stunning.
Good golfing 'bance' coming up between Westwood and Poulter.
Kapur's fire has been extinguished...three pars in a row and he's still on -4.
Hunter Mahan finishes up with a 72 and a score of +1.
Tiger smacks his tee shot on the 18th and he's looking a little nervy as his ball dives into the long stuff.
McDowell and his wonderpants (they're blue by the way) and he finds the thick rough as well on the 18th.
So here comes the hacks by the big boys on the 18th....G-Mac up first and he thrashes it out into the middle of the fairway. I'll give that a 8.5 / 10. Tiger next, although his rough is not as bad. Tiger smashes it out, grits his teeth and he looks pretty satisfied. 8.5 / 10
Italian Francesco Molinari making his steady move. Three bogeys in the front nine but four birdies and a whole bag of pars and he's on one under and looking pretty dangerous.
Woods has pulled his putter out.....rolls it onto the green and he'll have a tricky 17-footer for par.
BBC commentator Peter Alliss said earlier that the greens (and almost the fairways) are looking like the courts at Wimbledon in the final weekend. A pretty accurate description.
McDowell with a par putt,......it takes a bobble and drifts left. In it goes for a bogey and he finishes with a 75.
Can Tiger save another par?...how big could this be in three days?
IN IT GOES.....Tiger wraps up a 69 and he is right in there. A few wild shots in there but that's a good day's work from the world no 1.
More of the same on Friday morning and we'll get going from 0900 BST. Will some of the top boys stop moaning about the greens? Can Zach keep his nose in front? And watch out folks - Tiger Woods is prowling but there are plenty of big boys ready to pounce like Mickelson, Jimenez and Cabrera. Drama guaranteed. I look forward to having your company. Night.
Morning everybody. Plenty of drama yesterday. Up for some more golf today from magical Muirfield?
Only 20 players broke par yesterday. We had a broken six iron (Charl Schwartzel) , broken heads (Rory), moaning galore from Poults and Mickelson and a sizzling 66 from a man called Zach.
How will it go today? Eyes down...let's go. Nice to have you onboard.
Expecting the weather to change things today? Forecast is saying it will continue being sunny, warm with the breeze cranking up slightly at lunchtime. Who's getting the kettle on?
A shocker of a day so far for 1998 Open champ Mark O'Meara. He will have gone to bed last night with a huge smile on his face as he closed on the leaders on -4. This morning...ohhhh dear. Four pars, two bogeys and a stinky double on the sixth and he's plummeted back to level par.
I've got a mate who splashed some cash on Luke Donald last week. He will have been spitting in his tea last night...+9 for the former world No 1. He's started with a birdie today though...+8. 17 more of those and he may have a chance.
British golf fans listen up......LEE WESTWOOD...he's marching. A pair of threes this morning, birdie birdie, tweet tweet and he's on -1. Solid stuff. More importantly, he's ditched his hideous lime shirt and opted for a dark grey number. Solid again. Way to go Lee.
Two years ago Darren Clarke was kissing the Claret jug. This year? He might just be dreaming again after carding two pars and three back-to-back birdies to move onto -2. Dazzling start.
