Sophia Dunkley's maiden one-day international century laid the foundations for England to secure a 114-run victory over South Africa in the second women's ODI in Bristol.
Dunkley's ton helped England reach 337-5 at the end of their 50 overs after choosing to bat first, with Tammy Beaumont and Emma Lamb having got the hosts off to a superb start with an opening stand of 127.
She was well-supported by Nat Sciver as they put on 142 for the third wicket, with all four of England's top order passing the half-century mark.
A strong start to South Africa's reply from Laura Wolvaardt and Andrie Steyn gave them hope of chasing that down, but they were ultimately dismissed for 223 as the home side took an unassailable 2-0 lead in the three-match ODI leg of the tour.
