Mickelson pounds another drive down the 15th, here's Day with a peachy chip up the 18th green. Els's fourth at 15 comes up short, good luck getting up and down from there. Tiger is back on the range already, no-one can say he isn't trying. Hoffman can only par 13, stays -11.

Els finds the drink on 15, here's Mickelson with a naughty par putt on 14, from about four feet... straight down the pipe, after much deliberation, he stays -10. Hoffman gives himself a chance of an eagle, here's Spieth with his third... looks like it's going to skip through but suddenly stops, like a startled deer.

"I have laid out the plan of the course here at the top of the 15th. The interesting thing about this golf course is that no two holes run consecutively in the same direction so if there is a breeze about you have to be careful, it is always switching and always changing.

"Another interesting feature about this course is there are no fairway bunkers between the eighth, which has a fairway bunker, and the two on the 18th. There are only 44 bunkers on this course, but none on the majority of the back nine."

England's Justin Rose makes birdie on 13 to get to eight under, Dustin also gets a shot back after that double at 12, he's seven under. Spieth cutting through the woods and back onto the 13th fairway, amazing how these pros never seem to hit a tree when they do that.

Tiger Woods, who shot a 68 and is six under for the tournament, speaking to BBC Sport: "It could have been a really special round today, I could have gone really low. I made a crazy birdie at 13, stupid bogey at 14, stuffed it at 17.

"We saw what happened in 1996 [when Greg Norman blew a six shot lead on the final day], so anything can happen. On this course you can play well, but if you miss your spot by a foot then the next thing you know you have a 50-footer. It has been so hot and humid that the greens have not sped up."

Dustin has got a horror putt through the fringe at 13 but he does pretty well, leaving himself a five-footer for birdie. Japan's Matsuyama in with a 70, he's five under and tied for 11th.

Mickelson takes no prisoners on tee at 14, smashing one down there. Spieth at 13... his arm shoots right, like an Italian traffic director, and he's found jungle. Rose with a cute chip at 13, but it races five feet by...

Mickelson putting up the hill at 13, for eagle... trickles by, leaves himself four feet coming back. Makes it, he moves back to -10 and six off the lead. Casey of England makes par, stays seven under.

Rose clatters one down the 13th, no dramas there. Hoffman with a great save at 12, he stays -11. Spieth follows him in, but his putt is for birdie - the kid leads by five again on -16.

"The flag is blowing in one direction on the 11th and then blowing in another direction on the 12th. It plays havoc with your mind."

Mickelson's approach at 13 and he's into the guts in two. Perennial contender Jason Day of Australia is two under after 16 and -5 for the week. Hoffman with a fairly conservative bunker escape at 12, he's got a tricky one coming back for birdie.

"Was stood two yards from Tiger on 10th - was about to tee-off only to be interrupted at the very last moment by a coughing Garcia. Little love lost."

Rose for birdie on 12... slides it by, stays seven under. That's a double-bogey for Dustin on 12, although he'll probably get them back again at the par-five 13th. Woods finishes with bogey for a round of 68 and six under for the week. All is not quite right with his game but he's still battling harder than anyone.

Alex Haworth:, external Nice to see that Rose is continuing the English golfing tradition of missing loads of putts when in contention.

Andrew Priestley:, external One of Spieth / Mickelson is going to go birdie crazy on the back-9. Hoping it's Phil to close the gap, but I think it'll be Spieth.

Dustin Johnson is making a right old dog's dinner of the 12th - almost finds water off the tee, chips into a bunker, races it by with his escape. Hoffman makes a longun disappear on 11 to get to -11 and four off the lead. Spieth makes par.

Woods from the pine straw at 18. Cuts it round the corner and into sand, that's not an easy escape. Hoffman into 11... over on the right like Spieth, and just about everybody else. It's been a tough day for 58-year-old Mark O'Meara, champion in 1998 - he's six over through 14, and three over for the week.

Here's Dustin with his birdie putt at 11... "don't forget to hit it," says Ken Brown on commentary, and he does just that. Par, Johnson stays eight under. Mickelson walks away with a par at 12, stays nine under. Spieth aborts his swing at 11, steps back in and finds the green. Safe, but wise.
