Canberra, Australia: Opener Aaron Finch scored 109 and Steve Smith added an unbeaten 73 off 55 balls as Australia notched an imposing total of 329 for five after winning the toss Wednesday and batting first in the third one-day international against South Africa.
Finch and David Warner (53) made a typically aggressive start to the match at Manuka Oval, racing to 118-0 before Vernon Philander took the first wicket in the 20th over.
The 28-year-old Finch had his fifth one-day century when he hit consecutive boundaries off Imran Tahir to reach 99, then took a hurried single when the legspinner misfielded.
Finch (109) was clean bowled by part-timer A.B. de Villiers in the 41st over.
The five-match series is level 1-1 ahead of matches Friday in Melbourne and Sunday in Sydney.
