England subjected South Africa to a 38-run hammering in the final Twenty20 of the series, hitting 176 runs from their full allocation of overs before restricting the tourists to 138 for six.
In what will be a confidence-booster for the Commonwealth Games, Amy Jones (28 off 18) and Maia Bouchier (18 off 17) both found some form, while Alice Capsey – batting for the first time in international cricket – smashed 25 from 17 balls in the No 3 position.
Capsey was eventually caught at mid-off trying to go over the top, while Nat Sciver (24 off 24) and Danni Wyatt (30 off 25) were bowled by successive deliveries in the 11th and 12th overs, as Nonkululeko Mlaba finished with career-best figures of three for 22.
But England saved the best for last as – despite wickets falling at regular intervals – Sophie Ecclestone showcased the depth in the lineup with a 12-ball 33-run cameo at the death.
