Another?!
Has Richa Ghosh been caught down the leg side? Wicketkeeper Lauren Winfield-Hill likes it, and convinces her skipper for a review.
India international Richa Ghosh joins Danielle Gibson in the middle.
Both are aggressive batters, confident in scoring at a high strike-rate and that could help them here if they are going to play fearlessly.
Gibson gives a glimpse of her intent, heaving Macdonald-Gay down the ground without much timing and just for a couple.
I wonder how Grace Harris is feeling after this one...

Bit of a mindless shot from Kerr, she was looking good out there.
It was a decent ball from MacDonald-Gay but Kerr has played all around it.
Kerr b Macdonald-Gay 9 (Spirit 31-4)
London Spirit's struggles continue.
Amelia Kerr tries to get things going, starting with the boundaries in the previous over, but takes a big swing at a full, straight one from Macdonald-Gay.
The youngster's impressive Hundred continues.
Back-to-back fours from Amelia Kerr as she tries to force a bit of pressure back on to the home side.
She drills a wide one from Eva Gray through the covers before lofting one over mid-on for another.
And just to add a little more chaos, Gibson sets off for a single from the last ball of the powerplay, and survives after Alice Capsey's throw is wide.
It's all happening!
Marizanne Kapp started things perfectly for Oval Invincibles, as she so often does.
Danielle Gibson and Amelia Kerr have got a big rebuilding job on their hands here.

Terrible mix-up. Harris was becalmed in the middle of the pitch but Gibson has just run past her and run her out. I wouldn't want to be in that changing room afterwards.
Harris has said 'no' and sent her back but Gibson just went 'nah' and ran past her to run her out.
Harris run out (Macdonald-Gay) 1 (Spirit 15-3)
Oh. This is not good.
Grace Harris dabs into the leg side from her first ball and the immediate call from Gibson is for two.
But there's a bit of hesitation from both, a big mix-up that leaves both batters stranded in the middle.
Eventually it's Harris who is run out, having faced just one ball.

That's an unbelievable grab from Marizanne Kapp. In her follow-through and she had to react so quickly. It was quite low, too.
Heather Knight looked in good touch and it looked like it was going to take something spectacular to dismiss her. That's what we've just witnessed.
Knight c & b Kapp 10 (Spirit 15-1)
Kapp has two! A great catch in her follow-through to get rid of the Spirit captain.
Knight drives firmly, but the bowler does brilliantly to take the catch quite low to the ground in her follow-through, which is always tough.
A big blow for the struggling London Spirit.
Brilliant from Heather Knight.
She puts away a full toss from Macdonald-Gay with ease before beautifully driving the next for four through the covers.
A tough start for the 19-year-old seamer, bowling to the England skipper.
Throughout the Hundred, BBC Sport is running a feature series called England Next Gen, designed to look at players who may make the step up to international cricket in the next few years.
Two of those players are in action today, and you can read all about Sophia Smale and Ryana Macdonald-Gay.
The latter is on now to bowl early for the Invincibles.
Unsurprisingly, Kapp is going to bowl 10 straight through.
Knight dabs one down to third man for her - and Spirit's - first run, before Danielle Gibson clubs one aggressively down the ground for the first boundary.
Skipper Heather Knight is at the crease earlier than she would've anticipated.
And she edges her second ball... but it lands safely in front of Alice Capsey at slip.
Looking like a good toss to win for the Invincibles so far.

Just the start the Oval Invincibles wanted.
Holland will be a bit more than disappointed, she'll be utterly peeved. She's been bowled by an absolute beauty.
Holland b Kapp 0 (Spirit 0-1)
Well, that didn't take long!
What a start from Marizanne Kapp!
A tough ask of young Niamh Holland to come in to her first game and open the innings against one of the world's best bowlers.
A full, swinging delivery darts through her defences and Spirit lose their first wicket without a run on the board.
In terms of the table, Oval Invincibles need a win while London Spirit are desperate for one.
Defending champions Invincibles are in fourth with two wins from five while Spirit are yet to win a game but have been seriously unlucky with the weather.
They are just above Birmingham Phoenix, who are already out of contention for qualification.
Oval Invincibles: Lauren Winfield-Hill (wk), Suzie Bates (capt), Alice Capsey, Marizanne Kapp, Paige Scholfield, Cordelia Griffith, Kira Chathli, Mady Villiers, Ryana Macdonald-Gay, Eva Gray, Sophia Smale.
London Spirit: Niamh Holland, Danielle Gibson, Heather Knight (capt), Grace Harris, Amelia Kerr, Richa Ghosh (wk), Sarah Glenn, Charlie Dean, Alice Monaghan, Tara Norris, Lauren Filer.
