BBC Sport commentator live on BBC Two at Augusta"Totally unexpected. The wind got up, it wasn’t easy but it hasn’t been a very good day for high class action on the golf course."

Steve Tooker: A nervous final hole from Spieth sets up what should be a cracking final round on Sunday
Robert Snell: Jason Day is hanging in there. 3 off Spieth, think tomorrow might be his day.
Wide open?published at 00:29 British Summer Time 10 April 2016
58-year-old Bernhard Langer two shots off the lead. England's Danny Willett and world number one Jason Day three back. Lee Westwood four back. It's not been pretty, this third round, but it's set up a humdinger of a Sunday showdown...

Spieth closes on -3published at 00:27 British Summer Time 10 April 2016
One-shot lead over Smylie Kaufman
Round of 73, one over for the round. Three shots dropped over the last two holes, and Spieth has gone from imperious to in touch in that last ten minutes.
McIlroy finishes +2published at 00:26 British Summer Time 10 April 2016
Tied for 11th, five shots off lead
Miserable round for McIlroy, the sole silver lining being that late collapse by Spieth. An eight-shot deficit is gone, a five-shot deficit is not quite impossible.

McIlroy +2
Surely this one will fall for McIlroy, his first birdie on the 18th - mais non, not even close, and that will be McIlroy's first birdie-free round at a major since the 2010 Open.

Spieth -5
50 feet from the hole, going uphill, and he's left that well short. Nine-foot bogey putt to come.

Spieth -5
Not given it enough. Miles short. looks like at least one more dropped shot from Spieth, which would see his lead cut from four shots to just two in the last two holes.

Andrew Cotter
BBC commentator live on BBC Two at Augusta"Spieth's caddie didn't like that shot but he knew and he is the one who hits the shots."

Spieth -5
Now then. deep in the needles, but at Augusta you've so often got a shot no matter how ropey your drive. Spieth can see a gap, and he fires a low punchy one away, bouncing and jumping, needs to get up and down from 75 yards to save par. McIlroy? Splendid approach, good pop at birdie to come.
Final pair on 18th teepublished at 00:11 British Summer Time 10 April 2016
McIlroy down the middle, Spieth... Spieth way right again. They've driven poorly, these two; the difference has been the younger man's touch with the putter.

-5 going to 18th
Can't rescue it for once with his putter, comes up just shy, lead back to three over Smylie Kaufman.

Ross Parker: Spieth is a special talent who will dominate the sport. You can tell that he's different as he's incredibly mature beyond his years.
