The Proteas Women wrapped up a series victory on Saturday when they beat Pakistan by 13 runs in Durban.
Being sent in to bat first, Laura Wolvaardt and Lizelle Lee made a strong start at the top of the order as they raced to a quick 50-run stand.
But, for the second game in a row, Wolvaardt was run out when she fell short of her ground for 27, while Lee departed three short of what would’ve been a decent half-century when she was caught behind.
Captain Sune Luus looked in good touch but she played a loose shot that sent her packing for 32 before Lara Goodall was caught by Omaima Sohail for 26.
Marizanne Kapp, though, once again went on the attack down the order as the Proteas Women cruised past 200.
She reached her half-century with two big overs towards the end of the innings as her team ended on 252-7 in their 50 overs.
Kapp and Ayabonga Khaka made early inroads with a couple of quick wickets as Pakistan slumped to 73-5.
Khaka, in particular, was devastating with ball in hand and made an important breakthrough breaking a big partnership between Nida Dar and Aliya Riaz, Dar departing for a well-played 51.
The Pakistan Women kept going at it but their hopes were all but crushed when Riaz became Khaka’s fourth scalp, caught by Nadine de Klerk for 81.
Requiring 22 runs from the final over, Shabnim Ismail picked up the wicket of Diana Baig as Pakistan finished their innings on 239-8.
The final ODI will take place on Tuesday.
