A performance composed by teenager Alice Capsey saw England at home to India in Bristol, with a seven-wicket win that clinched the Vitality T20 series.
India, whose derby win had set the decision, recovered from 35 for five midway through the stage to set a goal of 123.
After looking well placed, opening Sophia Dunkley fell just short of another 50 before substitute skipper Amy Jones only lasted five balls.
The South East Stars Capsey hitter, however, stabilized the ship alongside Bryony Smith to see England over the line in the 19th over.
England, showing a change when Issy Wong entered the field for Lauren Bell, won the draw, with Jones choosing to pitch first.
After Jones missed a staggering opportunity to fend off Shafali Verma on the second delivery of the inning, Wong struck to remove the opening with a knuckle throw that went in, fell off the batter’s foot and back onto the leg stump. .
India also soon lost Sabbineni Meghana – who had made half a century at the Derby – to a duck while Danni Wyatt took a nice dive catch off Freya Davies.
Dayalan Hemalatha walked away quickly without disturbing the scorers when Jones reaped a big lead from Sarah Glenn’s opening.
With India struggling to find borders, captain Harmanpreet Kaur (five) was next out, shot by Glenn as he stepped out of the wicket.
England successfully examined a lbw call against Sneh Rana (eight), Sophie Ecclestone’s low delivery hitting on the back foot, while India plummeted to 52 for six.
Jones then blocked Deepti Sharma, ending his revival attempts with a near run-a-ball 24, before wicketkeeper Richa Ghosh went on the offensive with three consecutive borders off Wong to push India into a century. .
Ghosh (33) was eventually stopped when trapped lbw attempted to wipe out Ecclestone in the penultimate over, India down to 103 for eight. Pooja Vastrakar finished with a flourish, undefeated 19 out of 11, and Radha Yadav was five not eliminated. Ecclestone claimed three for 25.
England rookie Dunkley, whose undefeated 61 helped England win with nine wickets in the opening match at Chester-le-Street, was soon in pursuit.
India ultimately broke the partnership when Wyatt (22) was caught deep in by Radha Yadav off Rana as England moved up to 71 for one midway through the stage.
After being frustrated with facing a Yadav maiden when she was at 49, Dunkley then lost her temper when she was thrown by seamer Vastrakar when she swung across a boundary.
India maintained the pressure as Jones (three) only lasted five balls before Yadav removed her from the stump, leaving the hosts suddenly stalling at 79 for three.
Capsey, however, soon calmed his nerves as the 18-year-old made 38 out of 24, with six limits, along with Smith’s 13 unbeaten to lead England to safety home.
Jones praised his team’s efforts, having taken on the role of captain after substitute skipper Nat Sciver retired from the field.
“I’m just proud of the whole group, the way they all came forward at different times was great,” Jones said on Sky Sports Cricket.
“It was very different and quite daunting to get into the first game, but as soon as we got to Durham it was clear that everyone was so excited and willing to help.
“As a group we knew it wasn’t ideal at first, so that’s why it makes it even better. It was great”.
Jones feels that Capsey has more than proved his worth. The England captain added: “She is so good, she has all the shots and she plays so freely.
“It’s nice to see and I’m very happy he’s on our side.”
