The Proteas Women continued their dominance over India with an eight-wicket victory in the opening T20I in Lucknow on Saturday.
The hosts batted first and posted 130-6 in their allotted 20 overs, with Shabnim Ismail taking impressive figures of 3-14 in her four-over spell.
In reply, the South Africans were dominant from the start, despite losing Lizelle Lee for only eight early on. Anneke Bosch, however, took the attack to the Indians and shared in a decent 90-run stand with captain Sune Luus.
Luus departed for 43 but Bosch kicked on to reach her half-century, getting the Proteas across the line with an unbeaten 66 in the final over.
The two teams will meet again on Sunday.
