England's Danny Willett with a long 'un for birdie on the last - will it indeed, beautifully judged, nudging up, one more revolution and it's... you swine, stops a few blades of grass shy. Solid Saturday however, and that'll do.

Three under for the day too, and if the Langer story is impressive, so too is the form of this 25-year-old on his Master debut.

"Yet another putt. Spieth has really steadied the ship after the double bogey on 11."

Never a doubt. His putting from within 10 feet is a thing of dead-eyed wonder. Spieth is going to lead the Masters for seven consecutive rounds. Whoah.

World number one Jason Day who is level par after his third round, tells BBC Two: "I would say so (close to his best golf). It is not quite as tight as my best but sometimes it isn’t and you have just got to get job done. Fortunately, to get back to even par is a good score. I was very pleased with grinding it out.

"It depends on where guys are at the end of the day for what I can do tomorrow. I like to be patient and gather momentum through patience so we will see how it goes."

And a doozy of a second shot, from 140 yards to the left of the pin, releasing it down the slope to within seven feet. Birdie chance coming up to go three clear - Matsuyama's bogeyed 16...

On the par-five 13th, and both men will see that as something of a waste. Spieth even par today, McIlroy five over, Spieth still leading by one.

The 58-year-old Bernhard Langer, who is currently fourth on one under, tells BBC Sport: "I expected the worst (of the weather). I played in really bad conditions yesterday and the way it started today the wind was even stronger. I thought we better hold on, be patient, play smart shots and I did for the most part. I was pretty pleased with the round.

On the age gap between himself and leader Jordan Spieth: “It can happen in the game of golf. There are not many other sports it could happen but in this sport a lot of things are possible. It would be a thrill to be paired with Jordan tomorrow. It was great to be paired with Jason Day. He is a very fine young man and we had a great time out there today."

"An absolute legend of the European Tour," Ken Brown adds.

A little harsh, but he had a long oen for an eagle and the outright lead, put it nine feet past and then missed the birdie that would have taken him level with Spieth. Opportunity knocked and was ignored.

McIlroy, hands down the shaft, tries to punch out and has to settle for a dribbler onto the fairway. Third shot on this par five, up and over 40 foot from the pin.

"It is not good for McIlroy in there. The new Nimbus 3000 is not working for him today."

One for the Harry Potter fans...

Another mighty swipe of the driver, another fairway left untouched. That's gone a mile right. Five over for the day already, he'll do well not to add to that on this 13th.

Four birds, three bogeys for the world number one. He's not out of it.

"Very good escape from Langer. Very well done. Remarkable."

Bernhard with a seven-footer for a bogey five on 18 - well played sir, well played indeed. 10 years older than the oldest ever winner of a major, Langer will go into Sunday's final round within touch of a miracle.

A miracle from Matsuyama, draining a near 30-footer that, had it not gone below ground, may still be rolling. Bang in it.

"Quite a bounce back right there by Spieth. These guys, the reason they are on top, is their desire of success is higher than their fear of danger."
