Angel Yin might enjoy chasing tied leader Lilia Vu today. The 24-year-old was agonisingly close to major glory earlier this year, when she lost out to Vu in a play-off at the Chevron Championship.

She will be playing with South Korea's Hyo Joo Kim as they start one shot off the leaders after strong finishes on Saturday.

Oh dear dear - Nelly Korda's cold putter does not seem to have warmed up in the Surrey sunshine as she narrowly misses a birdie on the first and then she drops her first shot of the day on the second.

This course has not been friendly to the world number one.

I think we are overlooking Hyo Joo Kim. She's been so steady, if you are looking for someone flying under the radar and a proven winner.

Nothing against Ally Ewing but I think the fact that it did concertina and suddenly we've got 10 potential winners today going into the final day.

That's what you want in terms of the contest. Had Ewing backed up Friday on Saturday we would have a different proposition and we would be admiring one of the great major performances.

They are great because they only happen now and again and backing up a low round is a difficult thing to do the very next day. But I don't think she is out of it.

Nelly Korda may be five shots back but don't rule the world number one out today - as she's in a great spot to launch an attack and really put some pressure on the leaders.

Korda has just the one major title so far but has nine other top-10 finishes, is the reigning Olympic champion and won in England at the Aramco Team Series just a month ago.

She beat none other than Charley Hull at Centurion last month as well...

With the subtleties of the greens, the fact that you don't have the green reading books any more and so those players with frailties with the short stick are actually being exposed here.

That's been the case with Minjee Lee and the case for Nelly Korda.

Ally Ewing let a five-shot lead at the halfway mark slip yesterday and said that she had taken inspiration from Brian Harman's amazing win at the 151st Open last month.

She headed out a couple of minutes ago with Sweden's Linn Grant, who has been improving at Walton Heath round by round.

Afternoon golf fans, and what a day it could be for England's Charley Hull as she chases her first major at the 47th Women's Open Championship.

The 27-year-old went close to winning the US Women's Open at Pebble Beach last month and is now tied for the lead at Walton Heath hoping to go one better.

Co-leader Lilia Vu will be tough to beat though as she's already won a major this year, while Angel Yin, Hyo Joo Kim, Ally Ewing and others are in hot pursuit.

And don't rule out world number one Nelly Korda either - she's five shots back but could easily make a run to put everyone else under pressure.

So sit back and stay tuned as this could be a cracker.
