Sophia Dunkley scored a maiden century as England beat the Proteas by 114 runs in the second women’s ODI in Bristol on Friday.
Dunkley’s 107 came off 93 balls, and included eight fours and two sixes.
Tammy Beaumont (58 off 81) and Emma Lamb (67 off 65) got England off to a great start with a 127-run opening partnership, before the latter’s dismissal in the 22nd over brought Dunkley to the crease.
While Beaumont departed a few overs later, Dunkley and Nat Sciver (63 off 47) continued England’s domination of the Proteas bowlers, resulting in a daunting total of 337-5.
In reply, Andrie Steyn (28 off 44) and Laura Wolvaardt (55 off 48) put on 87 for the first wicket, but both were dismissed in quick succession by spinner Charlie Dean.
Wickets fell regularly from then on and while Marizanne Kapp made a fighting 73 off 59 balls, the Proteas were bowled out for 223 in 41 overs.
England will take an unassailable 2-0 lead into the third ODI in Leicester on Monday.
