Alex Hartley
Former England bowler on BBC Test Match Special
It was a dropped catch from Charlie Dean. Beth Mooney slaps the ball to mid-off, it bounces just at the feet of Dean. Tahlia McGrath is caught ball watching, the throw isn't that great from Charlie Dean as she was on both knees. She lies face down in the dirt, arms flapping like some sort of bird.
McGrath run out (Dean/Jones) 4 (Aus 65-2)
Absolute chaos.
Beth Mooney drives towards Charlie Dean at mid-off. Does it carry? Not sure.
She gets onto her knees and throws to Amy Jones, with Tahlia McGrath only a few steps away from the non-striker's end.
The throw is wayward but Jones gathers, throws herself threw the air, and chucks the ball onto the stumps.
Dean, flat on the air, puts her arms out in celebration and Sophie Ecclestone and another England player climb on top in delight.
Left-arm spinner Sophie Ecclestone is on.
This could be a big period in the game.
Can the number one bowler in the world do some damage? How will Australia play her?

Image source, ReutersBeth Mooney is a dangerous player, purely because she knows how to tempo an innings. If she's there in five overs' time she will accelerate.
Target 187
A good over from Sarah Glenn.
The wicket and just four conceded. That has brought an element of control back.
Australia need 125 runs off 78 balls.

Image source, ReutersHuge moment in this game. Sarah Glenn with a breakthrough, we know how dangerous Healy can be.
Clever bowling, keeping the stumps in play, allowing the batter to make the mistake.
Healy b Glenn 37 (Aus 59-1)
Awful shot.
With fine leg up in the circle, Alyssa Healy shuffles outside off stump and looks to pull away for a boundary.
However she just misses the ball, which goes on straight and hits middle stump.
A rapid 37 off 19 balls for Healy though. She's given Australia the start they wanted and needed.
Alex Blackwell
Former Australia batter on BBC Test Match Special
Healy doesn't really care where the fielders are - she's just smacking it.
Target 187
Alyssa Healy again tries to reverse sweep with the back of her bat. Surely that adds another element of risk to an already risky shot?
More orthodox drives over cover and back down the ground bring boundaries for Healy.
Australia's powerplay. England need a wicket.
Ffion Wynne
BBC Sport at The Oval
That six was genuinely huge. The square boundaries are so long and she has cleared it with ease.
Love a crowd catch, too - I always wonder what I'd do if I ever get one. I'd like to think I'd play it cool, but it probably wouldn't end up that way.
I was really confident for England at the halfway stage but these two have gone up a gear now, and that's ominous.
Alex Blackwell
Former Australia batter on BBC Test Match Special
It's looking really dangerous for England. Healy is in a mood tonight, we've seen a couple of big sixes and none bigger than that shot - the crowd has to stay awake!
Target 187
Alyssa Healy is good at cricket. Pass it on.
She hits her second six of the over with an outrageous flick over mid-wicket.
Superb. A pleasure to watch.
Alex Blackwell
Former Australia batter on BBC Test Match Special
She only got the inside half of this but she was 100% committed to it.
Target 187
Shot.
One step down the pitch from Alyssa Healy and she just lofts Nat Sciver-Brunt over long-on.
This is ominous for England.

Henry reckons that is before the hospitality numbers are added.
Impressive.

Lauren Bell has gone well in this Ashes so far, but that was a pretty loose over from the England fast bowler.
Alex Blackwell
Former Australia batter on BBC Test Match Special
Bell will want to bring that length back, she's got no fielders down the ground and will want to hit top of the stumps or on the hip.
Target 187
England had an element of control in the first couple of overs but Australia are now well and truly back on track.
Beth Mooney flicks Lauren Bell to the square-leg boundary, before lofting her down the ground.
Alyssa Healy makes it 17 from the over with a guide - OK, maybe an edge - down the third boundary.
Alex Blackwell
Former Australia batter on BBC Test Match Special
Image source, ReutersEngland have done well to generate dots, forcing the Australians to do something to break that pressure. I think England have got their plans pretty well set, they understand where the batters are trying to hit the ball, they've got the fielders set for each individual.
Sophie Ecclestone was run out for 22 off the final ball of the innings.
But how crucial could those 22 runs, and this six, be to the final result?
