Thanks Ben. Right then, anyone else getting a bit angry with this dominance from Mr Spieth?

We need a close-fought contest don't we? Can the coming hours change things?

Danny Willet is lamping one into the par-five 13th hole. Heart of the green stuff and a full 20 feet for par as he has taken a drop there. Currently one under, work to do to stay in red numbers.

Kevin Na putting together a good round, he's four under through nine and two under overall. Here's Luke Reddy for a bit, see you later...

It's taken McIlroy and Mickelson about 45 minutes to play the first two holes, which is just ridiculous. If you were stuck behind them at your local municipal, you'd have stuck a ball up their backsides by now or gone in for bacon sandwiches. McIlroy is back to one under though - a nine-footer on the second after escaping from a greenside bunker.

Spieth pars 16 to stay -14 and five clear. Trevor Immelman, champion in 2008, has endured an ugly week, rounds of 76 and 77 for the South African. It's as if someone has erected an invisible brick wall behind Spieth and Hoffman, everyone below them on the leaderboard rebounding off it. Dustin Johnson moves to three under with birdie at five.

Schwartzel, just as he did yesterday, birdies two to get to two under. This tournament badly needs someone, anyone, to go out there this afternoon and shoot a 64, just so Spieth goes into the weekend with some hot breath on his neck. Hoffman doing his best - birdie at 13, he moves to -9 and five off the lead.

It must be said, what Spieth is doing to this course hasn't been seen since Tiger Woods formally announced himself to the world in 1997. The 21-year-old is currently playing the par-three 16th. England's Paul Casey suddenly finds himself fourth without having to do much, he's four under after two.

Looks like Garcia has had enough, another one gone at 13, he'll find himself struggling to make the weekend if he's not careful. Judging by that last putt, he's not being that careful. Here's Charley Hoffman, the only man in the field who has gone with Spieth today... solid shot into 13, he's got about 12 feet for birdie.

Spieth is six clear of Charley Hoffman with no one else emerging from the pack to threaten. Is there someone who can do it?

Dustin Johnson is a streaky old player, he kicked off with a double and followed that with an eagle to get back to two under. Another birdie for Spieth at 15. He played short of the water with his second on the par-five hole and nailed a wedge to eight feet before knocking in the putt. Simple golf and he is now 14 under and six clear of Hoffman.

Hideki Matsuyama has eagled two to get to three under. Still only 23, Matsuyama was earmarked for great things as a teenager and still might achieve them.

Mark O'Meara, champion in 1998, is in with the day's low round, 68 for three under overall and a tie for fifth. Kevin Na of the United States into the red with a birdie at eight, he's three under today.

Here's Charley Hoffman, the only man within seven shots of Spieth, putting for birdie on 12... nailed it, gets to eight under and five off the lead. Hoffman, playing his second Masters, is bogey-free today.

Rose has let another one go at the fourth, the chasing pack dropping like flies at the moment. Woods's birdie putt comes up short at 13 but he's one under round Amen Corner and two under overall.

McIlroy has a 13-foot putt on the first for par. He laced his drive down the middle but hit a wayward second left of the green from only 143 yards. The world number one chipped on but could not hole out and is back to level par. Playing partner Phil Mickelson in for a regulation par.

Woods was forced to lay up at 13 after hitting a tree off the tee, but Spieth showed previously that that's no barrier to making birdies at this hole. A club too short, he's got a monster putt for birdie. Here's Hoffman at the 12th and that's a doozy, he's got a 10-footer for birdie to get to eight under.

Friday's tee-times

Par for Spieth at 14, he stays 13 under but has a birdie - perhaps an eagle - chance at 15. Eight shots is the biggest 36-hole deficit a Masters winner has managed to overcome, or so I'm told. Poulter of England has birdied two and five, is one under par.

There is always something slightly melancholic about watching Sergio Garcia in a major - he started the day four under, is now level after 11. Jason Day, too, is in reverse, the much-fancied Aussie bogeyed 11 to drop to -3.
