"That was excellent - a nerveless shot, absolutely perfect."
... that's a tremendous effort, brought the ball down on the fringe and scurried his ball to within nine or 10 feet...
Spieth has left himself a beast of a shot, over the collar of a bunker - he's going to have to go high and mighty and see if it sticks...
Spieth has blinked again - a big cry of 'FORE RIGHT!' and his ball flies head-high into the patrons. Wild. Hoffman parachutes in to within a few feet of the pin.
20 of the last 24 Masters champions have come from the final pairing, so with Justin Rose edging to 12 under par with a birdie at the last and Jordan Spieth 16 under through 17, you'd bet on either the young American clinching a first major or Rose adding a second to his 2013 US Open victory.
Dustin misses with his par attempt, falls back to six under after a disappointing 73. That was some putt from Rose, slicker than cat sick across linoleum.
Rose for birdie at the last, slippery... NAILED IT! What a putt that was, the Englishman is in with a 67, including five birdies in the last six holes, and is outright second and four off the lead.
That double from Spieth has made the weekend that much more interesting. All of a sudden, the aches in Mickelson's limbs will be miraculously easing - that's what hope feels like. Spieth safely away at 18, as is Hoffman.
Spieth's par putt comes up well short, he's got a fair few feet left for bogey. Rose takes an age over his second shot at 18 and that's a fine result, although it's a snakey one coming down the hill. Another shot gone for Hoffman at 17, he drops back to -9, where he started the day. Spieth makes a double...
John Daly has spent the week selling his products on a table outside Augusta National.
"The 1995 Open champion is standing with his fiancée, Anna, in the car park of a Hooters, the chain of raucous bars staffed by scantily clad waitresses," writes Oliver Holt in the Daily Mail., external
"Now he does not drink. His focus is more on the three trestle tables loaded with John Daly merchandise. He has not played the US Masters since 2006 but he has been coming to Augusta for more than a decade to make money selling his products. He still does a brisk trade.
"His 45ft motor home is parked next to the stall. It's his pride and joy. Daly and Anna sleep in it during Masters week. Daly often sleeps in it when it is parked outside his homes in Clearwater, Florida, and Arkansas. It has Florida plates that read 'Lion 95'."

"He was thinking too much about that one. There was enough room to pitch that and that is where he shows his youthfulness, a slight agitation that comes too quickly."
Casey couldn't get much going to day and he's bogeyed the last for a 74 and -5 overall. Spieth has duffed his chip at 17, he'll be dropping a shot here. Glimmers of hope for the chasing pack...
Rose makes par at 17, stays 11 under. Here's Spieth from behind a couple of trees - and with a very laid-back camera standing no more than 15 yards straight in front of him - and he manages to scoop it up there, 20 yards short of the green. Mickelson with eight feet left for birdie at 18... misses by a whisker, cards 67 for 11 under and seven off the current lead.
American golf writer Dave Shedloski on Twitter:, external Four players now at -10 or better. Most players to finish double digit under par since 1975 Masters was six in 2011.
That's rotten luck for Dustin on 17, his chip ricocheting off the stick and off the green in another direction. Mind you, it was going miles by. Rose's chip just comes up short, he should knock that in for par.
... I think it's definitely safe to start saying Spieth is playing Tiger-esque, he's just pulled his tee shot at 17 into the trees...
Billy Horschel, who missed the cut, tweets:, external "Pretty damn impressive what Jordan is doing. Had a front row seat the first 2 days."
Spieth has nailed another one at 16 to open up a seven-shot lead, this really is Tiger-esque now, I think it's safe to start saying it...
Mickelson for par at 17 and he hasn't hit it, he drops back to -11 and six off the lead. Casey makes his par, he stays six under. Here's Rose into the 17th and his ball creeps off the front of the green and disappears out of sight, like a cat burglar retreating from a spotlit roof.
Tough day for Ernie, he's three over after 17 and two under for the week. Spieth at 16, and that's another doozy, stiffed it to within 10 feet. Hoffman nearly sticks his in, he should bounce straight back after that bogey at 15.
