Wolvaardt has grown through this tournament, there's a noticeable difference from the earlier games.

Laura Marsh races through another over and Laura Wolvaardt frees her arms to almost every delivery. She can't pierce the field, though, only able to sneak a single from the final ball.

Ralph Brooker: Come on England. Some good has to come from all this cricketing misery that I've been subjected to this week.

Mignon du Preez, in her third World Cup, is the next batsman at the crease. She pats away the final two balls of the over before heading into the middle for a chat with Laura Wolvaardt.

Unbelievable from Sarah Taylor. That's why she makes such a difference - having someone in a semi-final who can move that quickly with safe hands.

Here's the first experience of DRS for South Africa's women's team, as Lizelle Lee successfully reviewed an lbw decision from Anya Shrubsole...

...but her Western Storm team-mate Shrubsole had the last laugh a couple of overs later as Lee was bowled attempting a heave to leg.

There's some kids having face paint applied in the crowd alongside a massive inflatable cricket ball, which is covered in messages of support for England. Laura Marsh has got the ball in her hands and sends down a loopy first over, and a good, late dive from Alex Hartley cuts off a boundary from Chetty.

Chetty is a typical wicketkeeper, likes to play square of the wicket and guide the ball down to third man like that.

Here's Nat Sciver, and there goes Nat Sciver! Full from the bowler, dropping right in front of her toes, and Trisha Chetty rolls her wrists to shovel the ball through the field. And another boundary! That's not quite as composed from Chetty, going hard at a wide delivery, but there's no slip in place and the ball fizzes down through third man and into the rope. Sciver responds with a nice, full ball that just escapes Chetty's cut.

Against India, they bowled really full deliveries to Wolvaardt, she tried driving too hard and was bowled.

Ooft. Laura Wolvaardt has the most glorious of drives up her sleeve. She pushes a fullish delivery from Katherine Brunt through the covers, but a good dive from Shrubsole at mid-off keeps her to just a single. It's a bit of an up and down over from Brunt, still not quite finding her line, but just the three from it.

England have won 18 of their last 19 ODI matches against South Africa. That loss came back in February 2016 at Centurion, where the Proteas registered a five-wicket win with seven balls remaining.

Trisha Chetty is off the mark, albeit in slightly risky fashion. A little push across the field is pounced on by Fran Wilson, which stops Chetty in her tracks, but she recovers to get home for a single. And that's a gorgeous piece of timing from Laura Wolvaardt! That's four any day of the week, a handsome drive that races to the boundary.

Over the last 12 months, England have rebuilt themselves as a unit. They've got to chase now, under pressure, to get themselves into a Lord's final and handling pressure will be what it's all about. Heather Knight's been a brilliant leader, but this will be a real crunch point.

It's £2 for kids to get in at Bristol today. A day's cricket for less than a coffee. That's a good deal, in my eyes, and I love a pretentious coffee. Brunt continues and strikes Chetty on the pad, the batter looking to work the ball through the leg side, but that was heading down. Chetty gets forward to her next delivery but she still can't get off the mark as a ballooning little shot drops just in front of Jenny Gunn.

A decent crowd in. I'd have liked to have seen more, although the semi-finals are on weekdays rather than a weekend. If you're knocking around Bristol, there are tickets on the gate so come on down.

Here's Trisha Chetty at the crease, and she sees off a tidy over from Shrubsole with a straight bat. Shrubsole gets a round of applause as she heads back to her fielding position.

That's a poor shot from Lizelle Lee, not one she'd be proud of. She's a player who can really take the game away from you. Anya's attacking the stumps, it's good to see her back in the wickets with a smile on her face.
