Australia was seemingly halfway to victory with a disciplined bowling performance after putting South Africa in to bat in Abu Dhabi. Finch used spinner Glenn Maxwell in the second over and it paid off straight away with the wicket of South African captain Temba Bavuma.
Josh Hazlewood removed the in-form Rassie van der Dussen with his first ball and Quinton de Kock in his next over in a bizarre moment. De Kock tried to deflect the ball fine down legside, but the ball looped up off his bat and dropped onto his stumps as he looked around, bewildered at where it had gone.
Adam Zampa spun out David Miller and Dwaine Pretorius in the 14th over and South Africa, at 82-6, dragged itself to 118 in its 20 overs, with Aiden Markram top-scoring with 40 from 36 balls.
