Kagiso Rabada takes two wickets and wonder-catch as Australia square series

Paceman Kagiso Rabada took two more wickets as South Africa were defeated in a dramatic last-ball finish in Johannesburg.

Defending a total of 204, the Proteas new-ball duo of Rabada and Dale Steyn reduced the tourists to 32 for three before David Warner (77) and Glenn Maxwell (75) smashed 161 for the fourth wicket.

Rabada removed Finch with a 92mph yorker on the fourth ball of the reply and took a stunning catch leaping backwards at third man as Smith departed to leave the hosts in control.

Kent's summer signing returned to bowl the final over and looked to be a matchwinner when his 89mph yorker castled Warner but James Faulkner struck seven from four balls and Marsh hit two from the final ball to clinch a memorable win.
