England stuck with a winning formula as they opted to bat first, as they did in the third T20, but while that triumph at The Oval was set up by a fantastic opening stand, there was no repeat in Manchester.
Danni Wyatt-Hodge holed out off Shree Charani for her third single-digit score of the series before Dunkley skewed Deepti Sharma to point where Yadav took a fine diving catch.
It was typical of India’s efforts in the field and with wickets falling consistently throughout the innings, England found themselves in a perpetual rebuild.
A partnership of 35 between Tammy Beaumont and Alice Capsey was the largest of the innings but Radha broke that and sent the stand-in skipper on her way with a few words and long stare.
That wicket came two balls after what proved to be England’s last boundary until the end of the 19th over as India’s spinners bowled with impressive discipline and challenged the home batters to take them on.
What followed was a less than ideal combination of very few runs and regular wickets – 5-58 in the last 10 overs, to be exact.
Sophie Ecclestone, on her 100th T20 international appearance, and Issy Wong each hit sixes in the last over to boost England’s total but it always looked short.
