Smriti Mandhana, India’s opener, scored an unbeaten 79 to lead her team to an eight-wicket victory against England and force a final in the three-match Twenty20 series.
India needed to score 143 runs to win, and with 20 balls remaining in Derby, Mandhana smashed 13 fours in her innings.
Shafali Verma’s 20, and Harmanpreet Kaur, 29, not out, assisted her.
After being 18-3 and 54-5 earlier, England scored 142-6, with 17-year-old Freya Kemp scoring her first half-century by slamming an unbeaten 51 off 37 balls.

With Radha Yadav excelling in the field and Sneh Rana collecting 3-24, India significantly improved from their dreadful showing in the series opener on Saturday.
They were then supported by the outstanding Mandhana, who scored her sixth half-century against England and her 17th in T20 cricket with an elegant display of power and cunning.
Bristol will host the last T20 game on Thursday at 18:30 BST, followed by three one-day international matches starting on Sunday.
