Composed Smith guides Australia to series win

By Nick Said CAPE TOWN, March 9 (Reuters) – - Captain Steve Smith scored a breezy 44 to guide Australia to a six-wicket win over South Africa in the final Twenty20 International on Wednesday and a 2-1 series victory. After electing to bat, South Africa posted 178 for four in their 20 overs, boosted by a magnificent unbeaten 97 from Hashim Amla. Australia paced their reply perfectly, however, and profited from a fine opening stand of 76 between Shane Watson (42) and Usman Khawaja (33).
