Ashleigh Buhai and Hinako Shibuno are keeping the pressure on.

Both hit nice approach shots on the 13th to give themselves a go at birdies.

Morgan Pressel's birdie attempt just drops to take the American within two shots of the lead.

Over to the leaders...

Lizette Salas dips her knees as she just misses out on a birdie putt that would have given her the outright lead.

Just a par. Ko Jin-young gets her par putt in too.

Given that there are five players within three shots of the lead, it seems a good time to explore this question.

If there's a tie when everyone has finished their rounds, there will be a sudden death play-off.

Players will play the 18th hole until a winner is decided.

-16 Lizette Salas (13), Ko Jin-young (13)

-15 Hinako Shibuno (12)

-14 Ashleigh Buhai (12)

-13 Morgan Pressel (12)

-12 Celine Boutier (F), Park Sung-hyun (12)

Hinako Shibuno's eagle putt is a hair right of the hole, but she taps in for birdie, tipping her cap and smiling at the crowd in return for their applause. One off the lead.

Ashleigh Buhai knocks in her birdie putt too. Everyone is bringing their best as this major comes to an end.

Ashleigh Buhai's gone for the lay-up option on the 12th. It works out nicely as the South African's second shot lands about a foot from the hole.

She does it!

Ko Jin-young leaves the flag in, as always, and the ball bounces off the stick and into the hole. She and Salas share the top of the leaderboard.

Lizette Salas misses out on a birdie on the 13th. Now over to Ko Jin-young, who has a chance to tie for the lead...

Could Park Sung-hyun still have a say today? The world number two makes just her second birdie of the day. Morgan Pressel makes par.

Most people have decided to lay up and avoid the risk of going in the water on the 12th hole but Hinako Shibuno decides to go for it. Why not? She's only in contention at her first ever major.

The 20-year-old nails it, landing on the green off the tee on the par four.

Ko Jin-young hits a beauty of an approach on the 13th. The world number one is in with another birdie shout. A reminder that she is going for her third major of the year.

Lizette Salas' second shot doesn't land quite as close, but it's still pretty nice.

These two are such a good pairing to watch.

Oh no. It's all unraveling for Charley Hull on her home course.

She's now had two bogeys in her last three holes.

Ashleigh Buhai has an 8ft birdie putt to keep herself in the game. It slides past the right of the hole, though.

Hinako Shibuno sweeps the ball in for par and stays two behind.

Worth noting that Morgan Pressel made five birdies on the back nine yesterday. Is she about to make a charge and put the pressure on?

A fine second shot by Morgan Pressel sets up the chance for an eagle on the 11th. And she takes it. The American now shares fourth place with Ashleigh Buhai.

Park Sung-hyun makes par.

There is no shortage of fans around the 12th green. That's just what you need when you're going for a birdie putt that will bring you one step closer to winning your first major.

Lizette Salas pushes it wide and settles for a par.

Ko Jin-young is loving it, though. Her putt goes straight down the middle and the lead is down to one.

But after five bogeys on the front nine, fellow Englishwoman Bronte Law has just landed her first birdie of the day to go level with Charley Hull.

Doesn't look like it's going to be Charley Hull's day. A bogey on the 11th means she slips to five under.

There are one or two Korean fans at Woburn this weekend. World number one Ko Jin-young is their best chance of a winner currently. She's two behind Salas.
