Another fifty, the day after her maiden one, for Beaumont and it has come from 51 balls. Winfield thumps a half tracker from Yousuf high over mid-wicket for a single to bring up the England 100.

"I think the more these two bat together, this will be a feature the running. These girls need to bat together for long periods of time. Keeping the top five or six the same will help."

More spin from Nida Dar at the New Road End, not in a cap but with some dark glasses that a not really required in the heavily overcast conditions. Beaumont continues along her merry way and notches her sixth four.

Another misfield, straight through the legs, as England rotate the strike off the spin of Yousuf.

Here's Lauren Winfield hitting another four to bring up the fifty stand for England's openers.

Beaumont's wristy follow through is a delight to watch and she displays it with another back foot punch when spinner Mir drops short again. The openers have hit 11 fours between them so far, plus the two sixes.

"I think Tammy Beaumont and Lauren Winfield have set a brilliant platform for the girls. They've capitalised on the bad balls and put the bowlers under real pressure."

Left-arm spin from Sadia Yousuf, one of the three changes in the Pakistan team. She is another to bowl in her cap a la G Boycott, who would describe some of the deliveries as "buffet bowling." Beaumont helps herself to another boundary with a firm push through the covers off the back foot.

The be-capped Mir continues and is guilty of a leg-side wide, but to her relief she keeps the boundaries at bay.

"On the Pakistan team, financially the contracts are nowhere near as a hefty as for England or Australia players. In Pakistan one of the cultural aspects is that girls tend to live with their parents until they marry. So the money they are afforded on contracts, because they live at home, they don't have a need for another job. It makes full-time cricket effectively possible."

Maham, perhaps frustrated by an lbw that was correctly rejected for pitching outside leg-stump, tries a bouncer but Beaumonth seizes on it and pulls it away for another six. Before today she had never hit an ODI six but she has two today. Winfield keeps the momentum flowing too, a waist high full toss turned away for for four. Seven fours and two sixes in the powerplay.

"Apparently Tariq flew in at the last minute and went straight into the side today. Her seam position was a bit mixed, perhaps her lines and lengths weren't as consistent as they could have been. But what a wonderful opportunity to come to England and play against England, to be able to get the experience to play here."

The first sign of spin as the diminutive Sana Mir enters the attack, bowling in a cap with redundant sun glasses on top. Beaumont steps down the wicket and emphatically thumps another straight drive for four more, while Winfield pulls a long hop through mid-wicket for another boundary to bring up the 50.

Here's the first maximum of the day - Tammy Beaumont smashing Asmavia Iqbal for a straight six!

"They're going along nicely. The fact that there are short boundaries - 55m all round the ground -  it's travelling really quickly. I'm delighted with the start but they'll want to continue that and be ruthless."

Maham continues to plug away, with a slip and a gully optimistically waiting for a chance. After the fireworks of the previous over there are just the two singles in this one.

"I've been so impressed by way Tammy Beaumont has been batting and yesterday as well. She's just continuing the aggressive and positive intent from the World Twenty20. I'm keen to see how she plays and this is the way she does it best."

Beaumont's eye is well and truly in, a fierce straight drive that has the umpire ducking for cover races for four and then an even sweeter strike sails in a similar direction, this time over the ropes, for the first maximum. Another wide from Asmavia, the extra ball is delightfully driven through the covers by Winfield for four and it is an expensive over.
