Dustin has poured in another birdie from all of 40 feet up the hill at 16 to get to -8 and outright third. These late charges by a handful of players are in danger of making it an interesting weekend. Adam Scott of Australia made eagle at 15, also, he's three under for the week.

Poulter snatches at his par putt on 18 and that makes it a level-par round. He'll be here for the weekend, he's +1, just inside the cut line. Rickie Fowler finished on the same score after a 72 of his own, Scotland's Stephen Gallacher is going home, however, he's +3 overall after a 76.

"It is always difficult starting on your round when the leader is 14 under par and you are one under and you want some early birdies. If you don't get them you start forcing it.

"He has got to get himself together. He is in danger of missing the cut which looks like being two over. He needs some birdies on the back nine."

McIlroy on tee at the short 12th and he's overcooked another iron, he's got the strength of 10 men today and he doesn't even know it. Justin Rose makes birdie after that fine tee shot at 16, moves to seven under and into a tie for third with Dustin Johnson.

Dustin Johnson makes it three eagles for his round with that tap-in at 15 - that's a Masters record and he already jointly holds the record for most in a Masters tournament, with four. He's now seven under and has more crystal goblets than John Lewis.

Bill Haas moves back to -3 with birdie at 13, Rose gives himself another birdie chance at 16 courtesy of a magnificent tee shot. McIlroy's birdie putt at 11 comes up a revolution short, but here's Patrick Reed splashing in at the last for a birdie, a round of 72 and two under for the tournament.

BBC Sport's Ian Singleton at Augusta: "The weather here is slightly breezier than we've seen this week. When the sun is out it is sweltering but it is having to battle intermittently with clouds. Thunderstorms have been forecast all week and there is talk about bad weather between 4pm and 6pm local time. We'll see."

It is now 5:07pm local time. No sign of anything too bad.

McIlroy's second at 11... that's OK, but nothing more than that. Dustin's second to 15, could do with another pair of crystal goblets here, and he's going to get them - almost an albatross, he'll be seven under in a minute.

Two Englishman tied for third, Justin Rose and Paul Casey. But there is an ocean of rowing to do before they catch Jordan Spieth atop the leaderboard. Rose for birdie on 15... misses by a whisker, stays six under. Casey on tee at 13, fades when he wants to draw but that's OK.

Bishop Yinkus: Could Jordan Spieth be young Tiger Woods in disguise?

N J Pedersen: Sunday will be Day's day. He just needs to take it one day at a time, seize the day and celebrate like its Australia Day.

Rakesh Pradhan: Unless someone makes a charge Jordan Spieth could be getting measured up for the Green Jacket by the end of the day.

Jordan Spieth is out there practising his putting, which is a bit like Michelangelo practising his drawing having just completed the Sistine Chapel. Westwood on tee at 16 and he's into the guts. McIlroy on tee at 11 and he's given it some hammer. Casey has moved to six under, the Englishman birdied 12, a 14-footer, and is now third.

"What Rory needs to do is try and string a couple of shots together. He needs to get a bit lucky and get on a roll.

"He is an emotional player, when things go his way they go his way in a big way, but when things don't go his way, can he dig himself out? That is the question we have to ask."

Peach of a chip from Mickelson at 10, here's Dustin's second into 14, that's decent. McIlroy for birdie on 10 and he finally makes one to get back to +2 and inside the projected cut. Mickelson completes that up and down, stays -2.

Poulter for birdie on 16 after a good tee shot and he bends it in to get back to level. Casey's birdie chip at 11 lips out and dribbles six feet down the hill. Rose makes a good save at 14, stays -6.

Clubhouse leader Jordan Spieth: "I pretty much made everything that was in a decent range today. All in all it was two very similar days - putting the ball well and taking my chances. I felt the swing felt natural today and I'll keep working on it.

"It will be somewhat challenging [not thinking about winning but I have to set a goal for myself. Charley Hoffman is playing solid golf so I certainly can't let up and the course will get tougher."

Sergio Garcia is far from enthralled by his mark of two under. Not even four birdies in five holes to finish have cheered him up.

The Spaniard - majorless of course - is among many on social media paying tribute to Jordan Spieth.

Great up and down from Dustin at 13, he moves to five under. Today we're witnessing one of the key differences between Tiger Woods and Rory McIlroy - Tiger's body language never, ever suggests he's beaten, while Rory's sometimes suggests he'd rather be anywhere than struggling out on the course. Great second from McIlroy into 10, birdie chance - and he needs it.

Dustin Johnson putting through the fringe at 13 and, not surprisingly, his ball has come up well short. Kevin Na has put together a pretty handy round today and here's another fine approach at 18 - make that putt and that's a round of 65. Schwartzel, winner in 2011, birdies 10 to get to four under.

VB: Rory McIlroy has mentally got on the flight home. Hopefully everyone can shut up about a career slam and enjoy Spieth's masterclass.

Blerghhhhhh: Come on then Justin Rose, strong finish please. Make a quiet night in worth it.
