Ireland's Shane Lowry missed the cut but he is tuned in: "How good is it to see tiger back up there??? Reckon he will give it a run tomorrow," he tweets., external

Mickelson from sand at 12 and it's magical, stiffed it to within a few feet. Spieth and Hoffman safely away at 11, Rose putting for birdie up ahead... starts low and stays low, he'll stay seven under and miles off the lead.

Casey on tee at 12. Twirls the club, seems to like it, safely on. Dustin with that scoopy swing of his, sweet approach at 11, birdie chance. Matsuyama for birdie on 16 - hits it way too hard, skips over the hole and races by. Woods with another iffy drive down 18, ends up in the pine straw. Matsuyama makes that clutch putt coming back, remains six under.

Next up for Spieth and Hoffman...

What: 505-yard par four.

Why: Monstrously long. Tee shot to be threaded through corridor of trees. Skinny fairway. Slim green fenced off by water.

Hole 11 is currently the hardest on the course for the week. It's taking an average 4.43 blows.

Matsuyama gives himself another birdie chance at 16, here's Mickelson with an eight-foot saver on 11... misses, he drops back to nine under, leaving Hoffman outright second. Spieth makes that par at 10, stays five clear. Woods for birdie on 17... doesn't turn, he stays seven under.

Many thanks Aimee, this is Ben Dirs until stumps. I join you as Spieth executes a sweet bunker escape at 10, should save par. Hoffman from just off the green and he skips it over the cellophane bridge. Casey for birdie on 11... great effort, just breaks too soon, he stays -7.

Allan in Manchester: New champion on Sunday? I can see Lefty winning this easily!

Andy in Armagh: Rory reached the turn in 32 shots, Tiger reached the turn in 32 shots, now Phil has reached the turn in, yes you guessed it, 32 shots. Fantastic to see these three golfing superstars trying to reel Jordan Spieth in. More birdies needed though.

Toby, Bristol: If Augusta favours left-handers so much why don't more of these "world class talents" just play that way for the week? Look how easy Ronnie O'Sullivan makes it look...

Might be onto something there, Toby. We'd expect amateurs in their droves to try out your theory first thing tomorrow morning.

What does Rory McIlroy think of Friday's front nine? Is his mind filled with ifs, buts and maybes? He's on six under par going into the final day, but it could have been so different had he not faltered in the first half of the second round.

And just when we thought Jordan Spieth was starting to feel uncomfortable standing in the line of Phil Mickelson's fire, he collects a birdie on the ninth to dampen the flames. The American back to 15 under overall and a four-shot lead becomes five.

"I believe at the ninth tee Sergio gave Tiger the glare when he was forced to stop on his practice swing. Things are nasty out here at the Masters."

As many would have predicted, Tiger Woods comes away from the 15th with a birdie. As does his playing partner Sergio Gargia, who is -4 for the tournament. Phil Mickelson with a six-foot putt for par and it doesn't look straightforward, but it is if you're one of the greats. Plop. In it goes. A blemish-free round for Lefty so far.

Oh my. Bubba Watson a pimple short from saving par on the par-four 18th but it wasn't to be. One thing is for sure, there'll be a new champion on Sunday. Rory McIlroy finishes on six under for the tournament. The Northern Irishman could regret those two bogeys on the 16th and 18th.

"Woods and Garcia were just walking down the 15th fairway about 30 yards apart. The interaction between the pair has amounted to the grand total of zero."

No entente cordiale then between the two rivals.

Justin Rose started quietly, but the Englishman has birdied the seventh and ninth and is finally showing an interest in joining a party we all thought he'd forgotten about. Tiger Woods, on the 15th, has been stirring it up from the get-go and he's got two putts for a birdie... feather-soft touch, gently it rolls, about two foot short, leaving the American with a birdie chance.

Jon Evans:, external Mickelson has to be my golfing hero, always hope he pulls off a magic round. To go with his magic short game.

Steve Rose:, external If I enjoyed my job as much as Tiger Woods appears to enjoy his I'd quit!!

We'd started to forget about Charley Hoffman but up he pops with a birdie on the eighth. The man from San Diego is still a big deal, joining Phil Mickelson in the hunt for Jordan Spieth.

Phil Mickelson steps away from the ball, carefully examines what's lined up before him. He prepares to shoot, but steps back to practice once more before moving in again. Tension building. This time Mickelson goes for it and down the hole it goes. A birdie on the ninth. Lefty just four shots behind. Oh my giddy aunt, let it be tomorrow already.

"Four shots and Mickelson's in Spieth's wing mirrors. Five or six shots and you feel like you're on the open road but four shots feels like there's a little cop car in the mirrors creeping up in the distance."

We're back on the 14th, keeping Tiger Woods company. A wee putt for bogey... teases the cup... but eventually gravity does its job and the four-time champion returns to six under for the tournament. Oh, Rory. McIlroy finds the sand on the 18th. Not the grand finale he would have been hoping for. Bubba Watson into the bunker, too.
