Marc Leishman is faced with a long 57-foot putt for birdie on the 11th but that looks a difficult one to judge down the slope.

He does well to send it close before rolling in for par.

Brian Harman drops another shot though, tapping his putter into the green as he watches a 14-footer for par slide past the cup.

Even the world number two has those holes. But this one could cost Justin Thomas a tilt at the Masters.

The American miscues his third shot at the par-five 13th and lands in the water guarding the green.

A good chip could rescue him... that's not too clever either. He's way past the hole and faces a difficult putt... which he leaves short.

A triple bogey - and a potential tournament wrecker - incoming...

Ah, Amen Corner. This has seen off many challengers over the years. How will Justin Rose and Will Zalatoris fare today? Zalatoris goes first on the long 11th and lumps his drive down the middle. Rose... goes right. The Englishman could have a shot to the green from there, though.

Jordan Spieth escapes the dangerous par-three 12th with a par to stay five under.

He's two off the lead with six to play.

Hideki Matsuyama catches his approach into the 14th green all wrong, pushing it well off course to the right.

But a superb chip up the hill allows him to tidy up on the green from a few feet and save his par.

Corey Conners atones for his bogey on the 14th with a two-putt birdie on the long 15th.

There have been no eagles on the par fives on the back nine so far today. I wonder if the receptive greens will help those coming through.

-7 H Matsuyama (13), J Rose (10), W Zalatoris (10)

-5 C Conners (15), X Schauffele (14), J Spieth (11), M Leishman (10)

-4 J Thomas (12), B Harman (10)

-3 SW Kim (13), T Finau (12), B Wiesberger (12)

What's happened to Jordan Spieth here? The American tugs his tee shot on 12 a little left and it finds the cart path. He'll get a drop, but does so on to the pine straw and that could be tricky. Spieth, wedge in hand, bumps it on to the fringes and it scurries to within three feet of the cup. Well played.

Justin Rose and Hideki Matsuyama have company at the top of the leaderboard - and his name is Will Zalatoris.

The 24-year-old American, making his Augusta debut remember, beautifully rolls in a 23-foot birdie putt on the par-four 10th. Stunning stuff.

That comes after a difficult birdie putt for Rose, who makes a good fist of it and converts for a par.

Poor approach shots in to the 10th prove the undoing of both Brian Harman and Marc Leishman.

American Harman finds the right-side bunker and Leishman sees a wedge shot on to the green run back down the slope to leave him with an almost identical third.

Scotland's Bob MacIntyre is finishing strongly. He's just rolled in a 12-footer for birdie on the 17th to get to two under.

After Justin Rose, he's the only other British player under par.

Those damp greens benefit Justin Rose on the 10th. His second shot hits the front bank, clinging on to the green and leaving him with a putt. No doubt that would have slinked backwards if it had been drier.

Zalatoris, from a similar distance, plonks his ball closer and gives himself a genuine birdie chance.

Jordan Spieth's long-range birdie putt doesn't have the legs and he's tasked with another five feet to make up for par. No bother for Spieth. On he goes to the 12th at five under par, two back from the lead.

Here is another illustration of Justin Thomas' undoubted quality. The American puts that bogey on 11 behind with a controlled nine iron over Rae's Creek and onto the 12th green. From there, he finally sinks a putt to move back to four under and tied seventh.

Hideki Matsuyama looks extremely confident at the moment.

He plays his second out of the longer cut on the right of 13 and watches it sail over a tributary to Rae's Creek landing it on the green to set up an eagle putt.

But that pulls up short and he slides his second left of the cup meaning it'll only be a par.

That's a big opportunity missed to become outright leader.

His playing partner Xander Schauffele makes no mistakes though and two-putts for birdie.

The outstretched right arm of Justin Thomas on the 11th tee was not a promising sign. Going into the trees was not where the world number two wanted to be and, although he could punch out onto the green, he needed three putts from there.

Another fairway finder for Jordan Spieth, who is looking confident since returning following the rain break, and he thens finds the right of the green at 11 - safely away from the water lurking to the left.

Rose for the birdie, up the slope... again, a tad short. Not quite got to grips with the newly-soaked greens yet.

Over to playing partner Zalatoris, this for a share of the lead. Lovely weight, line not so hot.

A pair of pars. Both men go out in an even-par 36.
