Taking guard at 92 for four and with England’s chase of 222 looking precarious, newcomer Dunkley stamped her authority on the match with five fours and a six, finishing on 73 from 81 balls.
Asked to bat, India managed only a marginally better batting performance than they did in the first ODI, posting 221 in the 50 overs.
They got off to an ideal start with enterprising young batter Shafali Verma combining well with Smriti Mandhana to put on 56 for the opening wicket.
England’s chief destroyer was the medium pacer Kate Cross. Cross picked two of the first three wickets to fall and then ran through the middle-order to end with a second five-wicket haul in ODIs.
India Women: 221 in 50 overs (Mithali Raj 59, Kate Cross 5/34, Sophie Ecclestone 3/33)
England Women: 225/5 in 47.3 overs (Sophia Dunkley 73 n.o, Poonam Yadav 2/63). (ICC)
