Yealimi Noh led by three going into this final round but is only one ahead as she makes the turn.

So many of these leading players are struggling out there.

Call it now - will she get over the line?

Hit the thumbs.

There's not enough gas on that chip back from Charley Hull and when she pushes her birdie putt right it means she can only tap in for par. Her playing partner Lydia Ko collects her first birdie since the second hole.

Holes are fast running out for Hull.

After back-to-back bogeys Yealimi Noh manages to stop the rot at the end of the back nine with par hold.

No such luck for Esther Henseleit who has slipped back to two under.

Shiho Kuwaki's approach into the 11th comes up short but she's well entitled to think a decent up and down could yield a birdie here.

She's caught that way to thin mind and now has work to do with her flatstick. It'll be a par as her effort grazes the left edge and that may prove costly.

Meanwhile, her playing partner Haeran Ryu, is playing out of a greenside bunker and looks to be struggling to save her par. She knocks a long putt down towards the cup but it's always staying right.

One of those players could be Hsu Wei-ling who, after getting to -3 at the 13th has played through the next two holes in par.

She has three holes to go but given the way the rest of the top 10 are all over par for their rounds, she currently holds solo third place.

Posting -3 in the clubhouse would be a statement.

The way the leaders are playing at the moment, if someone can get in and post a score in front of them, they will have a real chance just sitting in the clubhouse.

Lottie Woad goes within an inch or two of an eagle with a stylish chip on to the green at the 11th.

The 22-year-old easily taps in for birdie.

Three shots off the lead and Woad is still in contention.

Charley Hull makes her par putt on the 12th and now drives the 13th green, well through it actually.

Can she get up and down for a birdie? This is wide open.

Haeran Ryu must be full of confidence having won the Women's PGA and Evian Championships, but now only two shots adrift of the lead, she whips her tee shot into a fairway bunker on the 11th.

Not what was called for.

Anyone can still win this at the moment.

The leading pair are rocking.

Yealimi Noh chips out of the sand to leave herself a putt for a bogey from about six feet and the American is able to roll it in.

Noh breathes a sigh of relief.

All of a sudden, the leaderboard looks a lot more tightly grouped after consecutive bogeys for Noh - even if playing partner Esther Henseleit also drops a shot.

It's who panics the least.

Having a good, reliable caddie is really important while having a playing partner you're comfortable being around can make a real difference.

Esther Henseleit and Yealimi Noh probably don't have that.

She's just got to go through her processes. Whatever she has, she's going to need to do to stop dropping these shots.

Uh oh, are things are starting to unravel for Yealimi Noh?

She chips out of the rough at the eighth but it skids off the green and into a deep bunker.

Haeran Ryu gets up and down and takes a decent par on the ninth after missing the putting surface off the tee.

But it's even better from Shiho Kuwaki, who zips into three feet and taps in for birdie. She is yet to finish inside the top 10 of an LPGA major but is just two off the lead now.

Charley Hull pulls her tee shot on the 12th. She may well be in a bunker there and unless she can chip in it will be the first par-three hole she has failed to birdie today.

The world number seven gets out of the sand no problem but her ball scoots on about six feet. Big par putt incoming, especially given the 13th will be well in range off the tee, which has been moved forward so that the hole plays 267 yards for the final round (official yardage is 353 yards).

A blemish on the card for Yealimi Noh as she drops a shot at the seventh.

The American, using the broomhandle putter, misses a tricky putt from approximately 12 feet.

Germany's Esther Henseleit manages to slide in for par. She's within two shots of the leader and will be looking to apply some pressure on the leader.

Get in, get in, Charley Hull is urging her ball to drop on the 11th but it stays about and inch right and slides just past the cup. But it will be a birdie for the Englishwoman who moves back up to a tie for seventh.

It’s not playing difficult in terms of the wind but the course setup is proving capricious for the late starters.
