Big moment. Here's Marizanne Kapp for her final five balls.
And she's pulled for four by Deandra Dottin!
It looks a pretty bad misfield from Eva Gray out on the boundary but there was a huge cluster of pigeons right in front of her that dispersed as the ball approached, and I think they might have got in her eyeline.

Another great sweep shot for Sophie Ecclestone. Here at The Oval, if you hit in front of square, you get real value and it races away.

Ecclestone has really added those sweep shots to her game, she has definitely improved on that.

Dottin who, says Sophie Ecclestone, as she sweeps Capsey for another boundary.
36 from 25 balls the equation now.

It's all in the hands of Deandra Dottin. It would be a huge wicket for the Invincibles, if they can get it. The Originals don't have a lot of batting to come so it all hangs on her.
Superchargers take crucial Hain wicket
Is this the game at Trent Bridge?
Sam Hain is out for 20 off 12 balls, caught at deep square leg off Northern Superchargers bowler Reece Topley.
The Rockets now need 43 from 20 balls with five wickets left as they chase 143.
Tom Kohler-Cadmore and Daniel Sams are the batters in.
All four of the Originals wickets to fall have gone to pace at an average of 12.5. The Originals have scored 24 runs from spin without losing a wicket.
Originals 86-4
The Invincibles turn to Alice Capsey for the first time.
And she's greeted by a sweep for four from her best mate Sophie Ecclestone!

The Oval Invincibles have only used five bowlers so far. It will be interesting to see if they stick to that or not.
Originals 80-4
Target 129
Ryana Macdonald-Gay responds well with a couple of smart slower balls that just apply the pressure back on to the Originals.

Bosh. There you go. That is Dottin all over, she has such good eyes and hands. Anything in that arc, she knows she has the power and that is always going to be a four.

If Dottin can face 20 or 25 balls, you feel the Originals have got a great chance here. She has started really well and can be really destructive.
Originals 79-4
That'll help!
Smashed straight down the ground for four by Deandra Dottin.
Pure power.
Rockets v Superchargers going to the wire

With this equation, you would normally back the batting side but in The Hundred, things can change so quickly.

Marizanne Kapp had never been hit for six before in The Hundred until then, it shows how fearless Deandra Dottin is.
Originals 105-4
Target 129
Massive!
Deandra Dottin is in the mood for this. She launches Kapp down the ground for six more.
The momentum swings once more...
Superchargers closing on victory v Rockets
Tom Kohler-Cadmore is out now and the Trent Rockets' hopes are fading.
It's a third wicket for Northern Superchargers captain Wayne Parnell too.
The hosts need 41 from 17 balls with only four wickets left. Remember the Superchargers were 9-3 in their innings after 10 balls.

Wellington lbw b Gray 6 (Originals 72-4)
Another!
Full and straight does the trick for Eva Gray, as Amanda-Jade Wellington plays all around it and doesn't even bother hesitating for a review.
The game is swinging the Invincibles' way.
