Northampton - England women's skipper, Charlotte Edwards, struck 75 from 61 balls to lead her side to a 42-run win and an unassailable 2-0 lead over the Proteas in the second women's Twenty20 (T20) international at Northampton on Wednesday.
England posted a hefty 141/3 at the end of their innings, and the South Africans in reply were all out for 99.
The hosts made a good start, posting 45 runs before Lauren Winfield was stumped thanks to quick moves by Trisha Chetty off Dané van Niekerk (1/13) at the end of the seventh over.
Sarah Taylor (15) added 38 runs to the board with her captain for the second wicket, speeding up the run rate before she was sent back to the hut by Moseline Daniels. The bowler struck for the last time when Natalie Sciver was caught by Shabnim Ismail for 14 in the 17th over, finishing with 2/28.
Edwards completed a second consecutive not-out score, including back-to-back half centuries against South Africa.
The visitors started strong, bouncing back well from the early loss of Lizelle Lee (4) in the second over. Van Niekerk and skipper, Mignon du Preez shared a 34-run, second-wicket stand off 30 balls before the latter was caught by Sciver off Danielle Hazell for 15 in the seventh.
England's experience shone through however, as wickets began to tumble after the loss of van Niekerk in the 13th over.
South Africa were 71/3 at that point and very quickly lost the rest of their wickets for just 28 runs. Jenny Gunn was the chief destroyer, taking three wickets for 13 and claiming her 50th T20 international wicket with the dismissal of Sun Luus (3) in the 15th over.
Sarah Taylor was another standout player for England, showing off her skills with the gloves with a hat-trick of stumpings removing Ismail (4), Chetty (6) and Marizanne Kapp (27) to see South Africa all out for 99 runs in 18.3 overs.
The third match will take place at Edgbaston on Sunday and will be broadcast live on SuperSport 5/HD from 11:15am (SA time).
