You can see what Amy Jones is trying to do there. Everybody is up on the off side but she just slaps it straight to extra-cover.
Jones c Bosch b Khaka 2 (Eng 137-5)
Taken at extra cover! Listen to that noise.
Amy Jones just didn't get enough elevation.
England are into the all-rounders/bowlers now.

It's Tazmin Brits again. Sciver-Brunt couldn't launch the ball out the ground. She's been so good, so reliable, but with the pace taken off the ball she didn't get hold of it. It was six or out.

A huge blow for England. A huge, huge blow.
Sciver-Brunt c Brits b De Klerk 40 (Eng 132-4)
Gulp.
This game swings again with the massive, massive wicket of Nat Sciver-Brunt. She has clunked a catch high to long-on and once you see Tazmin Brits standing under the catch you know it is going to be taken.
Is that the key wicket?

An unbelievable over for England. Exactly what they needed. But this is going to down to the wire. This game will be an absolute thriller.
Need 34 runs from 24 balls
Nat Sciver-Brunt finds the boundary again! Shabnim Ismail buries her head in her shirt at the end of the over. It has cost 14.
The game swings back England's way.
You can tell it's a Friday afternoon. Don't you people have work to do?

I love how calm Nat Sciver-Brunt is out there. Almost like she's in total control.
Need 40 from 27 balls
Ismail responds with a superb yorker.
Cricket is so good.
