Australia v South Africa: Steve Smith century secures series win

Steve Smith reached his century off 109 balls and struck seven boundaries

Steve Smith scored 104 off 112 balls as Australia beat South Africa by three wickets to take an unassailable 3-1 lead in the five-match one-day series.

Smith shared a sixth-wicket stand of 121 with wicketkeeper Matthew Wade as the hosts chased 268 in Melbourne.

Australia had slumped to 98-5 before Wade and Smith guided them to 219-6, and James Faulkner's unbeaten 34 helped secure victory with an over to spare.

Captain AB de Villiers top scored with 91 in South Africa's total of 267-8.

The fifth and final one-day international - which is the last match of South Africa's tour - takes place at Sydney on Sunday.

Australia then begin a four-Test series against India on 4 December - with skipper Michael Clarke battling to be fit for the first Test in Brisbane because of a hamstring injury which has kept him out since the first one-dayer against the Proteas.
