Another Gunn single, Wilson slices one past the despairing dive of the point fielder and it's away for four! The crowd rise with a palpable release of tension. 20 needed from 24 balls.

Here's the last England wicket to fall - a wonderful piece of bowling by Moseline Daniels.

When you hear a crowd vehemently clapping the ones and twos, you know what sort of moment it is in the match!

South Africa continue to rotate their three remaining seamers in one-over spells as Wilson guides Daniels for a single. Gunn hoicks a single which reaches long-on on the first bounce. Wilson forces another single to mid-off. 25 from 27 - nail-biting stuff.

At this same stage, South Africa were 191-6. Toe-to-toe!

Kapp finds her radar with three dot balls to finish the over well - England need 28 from 30 balls.

And South Africa were 191-6 at this stage too. Super Over, anyone?

She's trying to bowl that full, wider length delivery but South Africa have only been in this situation twice before. Collectively, this group haven't been in these situations this much where there's such a big prize at the end of it.

Kapp fires a couple of wides outside off stump - clearly not just the batters (and text commentators) are showing signs of nerves! 28 needed from 33 balls.

Oh, what's going on?! It was a bye in the end but I thought Wilson had got some bat on that. It was a yorker length delivery from Kapp.

Gunn into double figures with a single - while Wilson profits from another Trisha Chetty wicketkeeping fumble as they run a bye to the keeper. 30 needed from 33.

Pace on the ball, isn't it? Gunn just whipped that through the on side.

The seamer shuffle continues - Kapp for her ninth over, Jenny Gunn whacks her through mid-wicket for four! Good start to the over for England.

At this same stage, South Africa were 179-6.

Wilson can't get a slower ball away - but then pulls out an outrageous Dilscoop over the keeper's head for four! But a dot ball to finish means it's an even 36 needed from 36 balls.

South Africa's bowlers are going in one-over spells as Ismail switches to the Pavilion End for the first time. Wilson knocks a single, Gunn swipes one to third man, and Wilson again picks out Van Niekerk at short extra. 40 needed from 39 balls.

Ebony is out on the balcony, trying to alleviate the stress by having a little boogie!

The tall Jenny Gunn carefully surveys the field, before playing her first ball straight to that short extra cover position where both captains have excelled in the field today. An on-drive brings England two, as Shabnim Ismail rather dives over the ball at wide mid-on. A drive to mid-off... dot ball. But when Daniels strays down the leg side, Gunn helps herself to two to deep square leg.

England need 42 from 42 balls, and Gunn has four from four.

Jenny Gunn has been in plenty of different situations over her career. England are going to need her experience here. Katherine Brunt had a strong word with Fran before she left, saying "come on mate, you can still do this."

Brunt moves to 12 with a single down the ground from a full toss. A lot on Fran Wilson's shoulders now - she cuts the fifth ball straight to point, and somehow clubs the last ball into the ground, and it bounces over the keeper's head for a single. 47 from 48 balls to reach Lord's, and I'm starting to feel the tension...
