One of the wickets which left everyone stunned featured Faf du Plessis and David Miller's unbelievable effort near the boundary rope to dismiss Mitchell Marsh. Marsh tried to clear the ropes in the 18th over of the match, bowled by Lungi Ngidi. But he couldn't hit it neatly. It resulted in a catch that left everyone's mouth wide open.

Du Plessis caught the ball but had to throw the ball inside as the momentum took him over the ropes. Miller was there to back him up. He dived to complete the catch.
