So, Brunt on a hat-trick...

Anya Shrubsole into the attack, Iqbal moves quickly to get off strike with a single which exposes number 11 Anam Amin to the strike. Amin doesn't look too confident with bat in hand, but defends her stumps successfully before swiping a single over the keeper's shoulder to third man. An Iqbal single means she will face the hat-trick ball.

As well as survival, Pakistan may have another target in their sights - their highest score of the series, having made 165 at Leicester and 166 at Worcester. Will it be 167 here? Or 168 (now known as "a Beaumont" in women's cricket)? Or even more?

"It would be so good for Katherine Brunt to get a chance at this hat-trick because she hasn't been in among the wickets recently. She's gone away and worked on a few different things and it's paid off. If she gets that hat-trick she'll probably give us the greatest celebration of all-time!"

"That was a good end to Alex Hartley's bowling. She's come back with decent figures from her last five overs which were much better after some early nerves."

Now then, it's Alex Hartley's last over, from the River End. A single brings new batter Sadia Yousuf (a fellow slow left-armer) on strike. A slip in place. But Yousuf plays out five dot balls and debutant Hartley takes a few pats on the back from team-mates as her spell finishes.

"I feel like Katherine has got a wicket there with a new slower ball. It looked slightly different with the wicketkeeper stood up. She'll be pleased with that and Katherine taking wickets breeds confidence into the rest of the side."

Anya Shrubsole's back on the field, having departed after that juggling catch, and Hartley re-ties her hair before beginning her ninth over. Mir pulls a full toss for four, while Wyatt at mid-wicket dives well to cut off another aggressive heave from the Pakistan skipper, who lofts a single down to long-on.

We're into the last 10 overs - a theoretical 214 needed from those 10. With the emphasis on theoretical.

"Alex Hartley has been brought into the side to try to take wickets. Unfortunately she's not quite had the breaks today because of a combination of factors with nerves being a part of that.

"However, she'll be better for playing this game and with the winter England have with trips to the West Indies and Sri Lanka she will have a part to play. I think she just needs to get that first wicket. Hopefully she'll bowl out here and get it."

England turn back to the pace of Katherine Brunt, can the Barnsley speedster clean up the Pakistan tail? Iqbal is on the defensive, before turning her wrists to nudge a four off her legs and steer a two through point.

Here's Anya Shrubsole's juggling act at mid-on which removed Nida Dar.

Still Hartley must wait for that wicket. Four dot balls are followed by a single and a two, edged past the solitary slip. Meanwhile, drinks-carriers Kate Cross and Danielle Hazell share a joke in the England dug-out.

Time for Laura Marsh's last over. As a former seamer, she has rather a long run-up for an off-spinner, but it's been mightily effective today. Sana Mir paddle-sweeps a single to backward square leg, Iqbal finds a gap through mid-wicket where Danielle Wyatt is patrolling on the rope, and the last ball of Marsh's spell is... not the last ball of her spell as it disappears down the leg side for five wides. But Marsh can take her cap after a great spell, and she earns a round of applause when the Taunton PA announcer reads out her figures.

Hartley holds her head in frustration as Mir sweeps, doesn't connect properly and they run a couple of leg byes. Amy Jones then removes the bails, appealing for a stumping as Mir leans forward - it's signalled as a wide but Mir had kept her back foot grounded. Debutant Hartley, her fair hair fluttering in a light breeze, has 0-44 from seven overs.

Asmavia Iqbal is in at eight for Pakistan, the tourists stumble their way through a couple of singles, but it's a case of when England win this game - not if. Marsh is through nine overs of an excellent spell.

Here's the end of Sidra Nawaz's bold innings of 47 as she falls to Laura Marsh.
