UPDATE 1-Cricket--Warner returns from ban to star for Australia in opening win

David Warner and Steve Smith returned to international cricket on Saturday to see Australia through to a comfortable seven-wicket win over Afghanistan in their World Cup opener at Bristol's County Ground.

Warner top-scored with an unbeaten 89 while Smith made 18 as Australia easily chased down a modest target after Afghanistan, who won the toss and elected to bat, were bowled out for 207. The pair were back for their first official one day international after year-long bans following a ball-tampering scandal in South Africa.

Australia, whose captain Aaron Finch contributed 66 runs off 49 balls, reached 209 for three in the 35th over, ensuring a winning start to the defence of their World Cup crown. (Reporting by Mark Gleeson; Editing by Hugh Lawson and Tony Lawrence)
