9.25pm And that's the end of that. A hugely impressive performance from England - finished off by Ecclestone with both ball and earlier, bat, thanks to her 33 not out from 12 balls. That capped a hard-hitting approach all down the order, with Alice Capsey lighting the fuse after the first-ball loss of Sophia Dunkley, but after that it was all about the kids with the ball. Issy Wong with a fine maiden T20I wicket to Freya Kemp, the pick of the bowlers with two well-earned wickets on her own debut.

And with that, England complete a clean-sweep of the white-ball legs of the multi-format series. 3-0, 3-0 and a drawn Test giving them a 14-2 points victory. Can't say fairer than that. They head off to the Commonwealth Games next week with a real shot at a medal, thanks to a rejuvenated approach that, whisper it, could even give the Aussies a run for their money. As for South Africa, there's not a lot of joy. Nonkululenko Mlaba was excellent with the ball and Tamzin Brits hung in there with the bat. But they've had a rough time of it on this tour, and have been soundly beaten. Thanks for joining us, until the next time, good night!
