Adelaide: Australia captain Steve Smith has admitted his team shines the ball "the same way" as South Africa skipper Faf du Plessis, who has been found guilty of ball-tampering. The 32-year-old was sanctioned by the International Cricket Council on Tuesday after an incident in his side's win over Australia in the second Test at Hobart last week, where television footage appeared to show him ''applying saliva and residue from a mint or sweet, an artificial substance, to the ball in an attempt to change its condition''.
