A rare bright moment for Charley Hull on the par-four 16th as she picks up just her second birdie of the day.

Three bogeys and a double bogey have already wrecked the round though.

Jiyai Shin is smiling after leaving herself with another tricky six-footer. Too often has she been in this position. Is the tide turning?

Lilia Vu can barely walk towards her ball due to the wind blasting her in the face. She then misses her par putt, I think that's her out of it.

Meanwhile, Shin pushes her putt wide. An aggressive attempt, maybe due to the wind in her face?

A little fist pump from Lottie Woad as she drains from a dozen feet on the long par-five 14th. It's for a par. She knows how crucial that was.

Four to play and she leads her nearest rival in the race for the low amateur by three shots. And Spain's Julia Ramirez Lopez is already in the clubhouse.

Lydia Ko could not have marched down the 13th fairway and placed her ball in any better position. Stunning drive, leaving a mid-iron into the green, which she finds, to leave herself a dozen feet to get back within one of the lead.

Will she complete the picture perfect hole?

Jiyai Shin doesn't make the same mistake as Nelly Korda, clearing her tee shot over the bunker in front of the 11th green.

A long putt for birdie - the story of her day so far.

Jiyai Shin cleans up easy enough, but it wasn't so easy for Lilia Vu, who drops a shot. You wonder now is it a two-horse race?

What a three.

That bunker on 11 is nasty, no other way to describe it. So many have been stuck in it over the years. Nelly Korda went for the money shot, rather than floating a safe one over the flag.

Elite golfer.

A cracking stat for you. In rounds three and four, so far, the front nine has played in a combined 76 under par.

The back nine? Just the 227 OVER par. This ain't over.

WHAT A SHOT!

Arguably the shot of the day. From the bunker, over the ridge and inside 10 foot - unreal from Nelly Korda.

The ball could have easily come back down...

Perfection.

Lydia Ko took her drive, like the vast majority of players, down the left of the 12th fairway - there are a multitude of hidden bunkers for anything hit straight down the middle - and found more wispy grass.

It's not the thick rough you'd expect to find just off the fairway at most other majors, this stuff can tangle the club but you'll often get a decent lie.

Ko bumps her ball right of the flag and two-putts from 25 feet for a par.

Jiyai Shin rattles her par putt from six feet into the hole. After Nelly Korda went clear, she HAD to make that.

A poor miss from Jenny Shin, who can't afford to miss six-foot birdie attempts, it was a swinger to be fair. Rory McIlroy US Open vibes.

However, Nelly Korda from inside 10 feet makes no mistake.

That's the difference!

Here is one of the shots of the day from Nelly Korda on the fifth.

Ever seen a longer putt?

The 11th is a brute of a par-three. It's not overly long but there are several cavernous bunkers protecting a narrow green which is full of humps and bumps.

Lydia Ko has found the putting surface but is probably 60 feet from the hole and putting up a slope into the teeth of the wind. It's going to be slow. Ko doesn't give that enough of a biff and she's got five feet left for par. She's bogeyed this hole in every round...

...but today is different. She stood over the putt for an age, and then stepped away as the wind buffeted her. Ko returns over the ball with a slightly wider putting stance and drains her effort.

Nelly Korda's approach shot lands 15 foot from the flag. That looked good until Jenny Shin arrowed her shot to within six foot.

Back nine and moves are being made!

Jiyai Shin misses her 12-footer for birdie!

A big opportunity missed. Her putt looked good before it moved agonisingly wide of the hole.

Charley Hull's miserable weekend is continuing. After a three-over 75 on Saturday, she's now four over after 13 holes of her final round.

It's a disappointing end to what started out as a promising week.

Anything Jiyai Shin can do?

Nelly Korda sinks her own birdie from inside 10 foot to go back top with Shin.

Lydia Ko flicks a delightful wedge out of the rough down the left of the 10th that skips up to within six feet.

Another huge chance for the New Zealander and this time she nails it.

Another superb shot from Jiyai Shin and a smile. She attacks the par three and leaves herself a 12-footer for back-to-back birdies.

Lilia Vu will have a longer attempt for birdie, but still a nice shot.

Here we go, it is heating up!
