Lottie Woad stalks off the fourth green chuntering to herself. She's really not happy after a five-foot par putt lips out. The English amateur back to where she started the day.

Nelly Korda misses her long putt for birdie, but Jenny Shin shows how it is done and sinks it from around 12 foot.

What a start!

Like Nelly Korda and Jenny Shin - both Jiyai Shin and Lilia Vu drill their drives straight down the fairway.

Two brilliant approach shots from Nelly Korda and Jenny Shin leave both with good birdie opportunities on the first. A perfect start for both?

Defending champion Lilia Vu bossed last year's final round at Walton Heath to win her first Open title.

The 26-year-old shot an impressive 67 that day to win by six shots.

One shot behind leader Shin is a nice position to be in. Surely back-to-back Women's Open titles is too good to be true?

The last to do so was Yani Tseng in 2011.

So often defending champions blow up the following year at a major. Fair play to Vu, it takes an elite mentality to be in the hunt once again.

Lydia Ko is away with a solid par down the first. It feels like the New Zealander has been around for ever. It's nine years since she won the Evian Championship at 18 to become the youngest women's major winner.

She won the following year's Chevron Championship but that remains her only other major victory. However, she's in belting form having won the Olympic title a few weeks ago.

Ko has to be the big threat to the leaders today.

World number one Nelly Korda and Jenny Shin are under way. You'd imagine the winner will come from the top two groups, but golf is a funny game.

Two perfect drives down the fairway.

Only the lead group of Jiyai Shin and Lilia Vu to come now at 14:15 BST.

Georgia Hall, champion in 2018, is already finishing up her championship. The Englishwoman ends in style too with a 25-footer for birdie on the last.

She briefly threatened the top of the leaderboard earlier in the week but Saturday's four-over 76 ended her challenge.

A one-under 71 sees her end on two over. It's a finish that means she may need to rely on Suzann Pettersen making her one of four captain's pick to make next month's European Solheim Cup team.

As the leaders head out in the final round, see how we got here with highlights from Saturday's third round on the BBC iPlayer.

Watch here.

Never rule out the world number one!

Nelly Korda was the overnight leader heading into Saturday on eight under. Playing some unreal golf, it looked like her three-shot lead was only going to grow over the final two days.

If only it was that simple. Korda struggled on Saturday, carding a three-over 75.

Still only two shots off the lead, the 26-year-old two-time major winner will back her chances today.

The greats bounce back after a difficult round, can Nelly produce some of her best golf which helped her win the Chevron Championship earlier this year?

Two majors in a year would be some feat.

Charley Hull is on and off with a sleeveless body warmer between shots. It's that kind of day on the Fife coast of eastern Scotland. She's on the fourth green, staring down a 12-footer for par.

It creeps in the left edge. That's four fours for the English number one. A solid start and the only par five of the front nine up next...

Esther Henseleit is among those starting the day five back and like many before her, the German hits her second just left of the pin to allow the slope to feed the ball back down towards the hole.

That leaves a simple birdie putt and she's just four back.

Lydia Ko, who won the Olympic title earlier this month, hit a 71 on Saturday and is three off the lead on four under.

Out at 13:55 BST, could she put the pressure on the lead group with a couple of early birdies?

An incredible start for Hyo Joo Kim, who nails a perfect approach with her second to the first to register a sensational eagle to get to three under.

The early smile is soon wiped off the South Korean's face though as she finds trouble down the third and hands back those two shots with a double-bogey six.

On Saturday, two-time winner Jiyai Shin stormed into the lead at St Andrews.

The South Korean holed seven birdies in a five-under 67 as the former world number one reached seven under par.

Not much focus was on the 36-year-old, whose two major wins came in this event in 2008 and 2012, but she certainly rolled back the years to show she wants another Open title.

To win an Open, you must peak on Saturday and Sunday - Shin knows that all too well.

A one-shot lead is not much of a buffer, though.

There are birdies to be had out there. Japan's Akie Iwai has rolled in three on the spin from the fourth, including a 40-footer on the sixth, to get within five of the lead.

A par on the seventh stops the run as the wind and rain picks up.

English amateur Lottie Woad has had a sensational week so far and starts the final round just five off the lead.

The 20-year-old is the world's number one amateur and while she came into the Women's Open with eyes on the silver salver as low amateur, she's now in the hunt for a much bigger prize.

She hit the headlines in April when she birdied the 15th, 17th and 18th to win the Augusta National Women’s Amateur, at the home of the Masters.

She then finished joint 23rd on her major debut at the Chevron Championship two weeks later.

Anyway, how are the nerves Lottie? Well, she's found the green with two sparkling shots down the first and then rattled in a 20-footer for birdie. Game on.

Remember I said the wind has been challenging so far up in St Andrews?

Here is what I mean.

The weather forecast says "light rain and a fresh breeze", and given the difficult blustery wind during the opening rounds, I think the leaders will take that.

Links golf isn't easy, and looking at the wind and rain on TV - I wouldn't say that is light rain or a fresh breeze. Looks very, very windy and wet again.

The heavens may well open at some stage…
