When considering the bigger picture, the most significant part of the one-day international series against New Zealand was the arrival of 18-year-old spinner Tilly Corteen-Coleman on the international stage.

That she looked so at ease on debut in Chester-le-Street, while able to admit she could have bowled better, was a major boost to Edwards, who has long talked up the spinner’s talents.

Her emergence leaves Edwards with a difficult decision.

Sophie Ecclestone, fitness permitting, still appears a guaranteed starter in England’s World Cup XI but who will join her in the spin attack?

The other candidate is England’s third left-arm spinner, Linsey Smith.

Smith, a shorter, slingier spinner compared to the more Ecclestone-like Corteen-Coleman, was arguably England’s best bowler at last year’s 50-over World Cup and her skills of bowling in the powerplay – she bowled more than half of her World Cup overs with the new ball last autumn and took seven of her 13 wickets in that phase – are arguably even more relevant in T20s than ODIs.

It would be a big call to opt for the 18-year-old but Corteen-Coleman has done her cause no harm.

She took 1-18 in four overs in a T20 when 427 runs were scored during England’s intra-squad camp in South Africa earlier this year.

You could, of course, play all three left-armers, but that would probably mean leaving out vice-captain Charlie Dean and having a problematically long tail.
