CANBERRA, (Australia): Opener Aaron Finch scored 109 and Steve Smith added an unbeaten 73 off 55 balls as Australia beat South Africa by 73 runs on Wednesday to lead 2-1 in their five-match one-day international series.
After winning the toss, Finch and David Warner (53) raced to 118-0 before Vernon Philander took the first wicket in the 20th over.
Finch notched his fifth one-day century when he hit consecutive boundaries off Imran Tahir to reach 99, then took a hurried single when the spinner misfielded.
In South Africa's reply, opener Hashim Amla scored 102 before being bowled by Josh Hazlewood.
The last two matches will be played on Friday at the Melbourne Cricket Ground and on Sunday in Sydney.
