Target 107
A leg-side wide extends the over and Emma Lamb drives the extra delivery through the covers for two more.
Not out of the middle of the bat but into the gap and hauled back just shy of the boundary sponge.

Emma Lamb's body language changed immediately with that run, she's thinking 'Alright, I'm away!'
Target 107
Udeshika Prabodhani starts well with three full balls on the stumps to Emma Lamb.
The left-arm seamer strays a little with the fourth though and Lamb clips it past short fine leg for two.
England are up and running in the chase.
That brings us up-to-date just in time to see the England openers making their way out to the middle.
It's 107 to win in Durham. Sri Lanka's bowlers impressed in the T20s but they will have to surpass themselves if they are to win this one.
Emma Lamb will face the first ball for England.
The innings came full circle with Mahika Gaur brought back to finish off the innings with her third wicket, all bowled.
Sri Lanka were 106 all out in 30.2 overs with just 11 runs added in eight overs from the moment Harshitha Samarawickrama departed in the 23rd over.
All of which means that England need 107 to go 1-0 up in the three-match series...
Harshitha Samarawickrama was Sri Lanka's last hope and made a steady 35 before falling to Alice Capsey after a review.
That was Amy Jones' fourth catch of the innings and the England wicketkeeper's fifth - a record - came soon after to help Sarah Glenn remove Oshadi Ranasinghe.
Glenn got her third when she bowled Achini Kulasuriya...
Sarah Glenn got the third wicket before Lauren Filer had Hasini Perera caught behind down the leg side to claim her first ODI wicket.
Wickets two and three came back-to-back a few overs later as Filer put England in complete control...
Let's have a look at some of the best of the action from the Sri Lanka innings.
Chamari Athapaththu looked to have carried her form from the T20 series into the ODIs with a couple of early boundaries.
But she was stopped in her tracks by a beauty from Mahika Gaur, who then produced another to bowl Anushka Sanjeewani...
Mahika Gaur: 3-26 from 6.2 overs
Kate Cross: 0-21 from 6 overs
Sarah Glenn: 3-20 from 8 overs
Lauren Filer: 3-27 from 5 overs
Alice Capsey: 1-12 from 5 overs

Mahika Gaur and Lauren Filer both took three on their ODI debuts, joining Issy Wong, who also took three on her debut.
If England can get her bowling well they'll have decisions to make with the new ball.
Superb from the England bowlers and it was all started by Mahika Gaur on debut.
She bowled Sri Lanka's star player Chamari Athapaththu and the visitors never really recovered.
Gaur ends with 3-26, her fellow debutante Lauren Filer also took three wickets, as did leg-spinner Sarah Glenn.

There was a nice little bit of shape back in. She's still moving the ball in the 30th over!
It is a very, very good day for Mahika Gaur.
Melissa Story

That is a brilliant ODI debut for Mahika Gaur.
Prabodhani b Gaur 2 (SL 106 all out)
Bowled 'er! That's the way to finish off an innings!
It's a third wicket on debut for Mahika Gaur as Udeshika Prabodhani is comprehensively bowled.
A full, swinging delivery from round the wicket and the batter played all round it. Middle stump pegged back and Sri Lanka are all out.

Anya Shrubsole once stood on a dead pigeon. She had flip flops on so it went through her toes.
She was just walking through Worcester town centre, minding her own business and didn't see it.
Just two wides from Sarah Glenn's over.
One was well down leg but the other is one of those I always think is a little harsh in that if the batter had stayed in position, it would have hit her.
Instead, Inoka Ranaweera moves inside the line and gets the extra run for her side.

There was a time where me and Anya Shrubsole were contemplating retirement and we weren't sure where the next seamers were coming from.
But, with how good domestic cricket has come along, it has really encouraged seamers like Lauren Bell, Mahika Gaur and Lauren Filer to come out of the woodwork.
Katie George was a really promising prospect a few years ago and I still think she's got that in her.
Two singles and a wide from Mahika Gaur's over.
The extra ball is left-arm seamer's best of the set, swinging it back in to the right-hander from round the wicket.
Just past the inside edge but going down leg. Time for drinks.

I would have liked to see Heather Knight give Mahika Gaur three wickets to run in at here.
Looking at the replay, Achini Kulasuriya was absolutely nowhere near that delivery from Sarah Glenn.
It's a wicket maiden for the England leg-spinner and now Mahika Gaur is coming back to try and finish off the Sri Lanka innings.
