"You could feel that frustration building. The delivery was a little bit wide and Sarah Taylor was trying to do too much. With Edwards going so well, she's missed out a little bit."

"Bangladesh's fielding has much improved since the last time we saw them in 2014. They've moved a fielder to very fine leg, covering Sarah Taylor's release shot, meaning she's going to have to keep nudging it for now."

Edwards gets a fresh pair of gloves between overs from one of England's non-combatants - I think it was Rebecca Grundy - and Bangladesh introduce their sixth bowler, off-spinner Khadija Tul Kubra. There's a big appeal as Edwards misjudges a slog-sweep against a loopy delivery with a bit of air, that's close... but umpire Martinesz is unmoved.

The new bowler is Fahima Khatun, a leg-spinner with a rather jerky run-up who is no relation to her namesake Salma Khatun who took the new ball. (She's also a contender for the Bespectacled XI). Taylor and Edwards find fairly easy pickings against the 23-year-old leggie, who took 2-31 against India in the opening game of the tournament - five from the over.

Edwards expertly cuts a four past backward point, her opposite number Jahanara has a moan at the fielder - but it's not exactly the fielder's fault when the bowler serves up a ropey short, wide delivery, is it? Even if she is the captain? That's 50 up for England. Edwards turns her fifth four of the day through mid-wicket - her 29 has come from 22 balls.

"I'd never change Edwards and Taylor, but you do need other players to come through. There have been just eight sixes from the other England batters since the last T20 in 2014. That, for me, says a lot. From teams like Australia we're seeing about four sixes an innings. When you can hit big, it really takes the game away."

Stumping chance! Taylor down the track to Jahanara, misses, keeper Nigar Sultana (standing a couple of yards back) underarms it at the stumps but she misses too. To add to Bangladesh's frustration, it's signalled as a wide.

Medium-pacer Lata Mondal into the attack, no great pace and Edwards is able to club her wide of mid-on for four. Another "please hit me" delivery is helped down to fine leg for four more by the England skipper, who is the most experienced female player in the world in this format.

"Charlotte Edwards and Sarah Taylor have scored 632 of England's T20 runs in total since the last World T20 in Bangladesh. Everyone else has scored 702 runs. That's just 70 more runs than those two batters alone."

The bad news for Bangladesh is that by removing Tammy Beaumont, they've brought Sarah Taylor to the crease. The Sussex keeper is the number two-ranked female T20 batter in the world, with only the borderline-superhuman Australia skipper Meg Lanning ahead of her. Taylor is off the mark with a single, and Jahanara has 1-10 from two overs.

"Beaumont had the right intent - trying to keep that aggressive approach - but she got herself into trouble going wide of the ball. She'll be frustrated. This tournament is really important for her breakthrough, and she and Edwards had been almost toying with the field."

Salma Khatun spins down a second over, still bowling in a cap - perhaps she's a fan of a certain G Boycott, who used to do that? There's a brief mix-up as Beaumont pushes the ball to mid-wicket and sets off for a run, but Edwards wasn't interested - thankfully as the fielder makes a sprawling stop, Beaumont can regain her ground. And Beaumont celebrates by launching England's first six of the tournament over long-on! A single takes her to 18 from 13 balls - Edwards paddle-sweeps a two to reach 13 from 11.

"Tammy Beaumont is very good straight down the ground - she just slightly adjusted her feet for that four, a really nice swipe over the top. Then comes a classic shot from Edwards for another. What I like about her is she never overhits."

Nahinda Akter replaces the captain after one over - she's a left-arm spinner. And to make the rest of us feel old, she was only born in March 2000... Beaumont is relishing her chance at the top of the order, coming a pace or two down the wicket and smacking a four over the bowler's head. Captain Edwards unleashes a more textbook extra-cover drive for four, and this has been a decent start from England.

Off-spinner Salma Khatun takes the second over, bowling not only in sunglasses, but also in a cap. Not much turn at this stage. Edwards sweeps a two from outside off stump, and a single means both openers have five.
