South Africa’s Dean Elgar doubts Australia can keep up ‘nice guy’ approach

South Africa opening batsman Dean Elgar doubts Australia can keep up their \'docile\' approach to Test cricket as the tourists slip towards a heavy defeat and a series loss in the fourth and final Test at the Wanderers. Following the ball-tampering scandal that resulted in Steve Smith, David Warner and Cameron Bancroft given hefty bans after the Cape Town Test, new Australia skipper Tim Paine said his team would cut out some of the boorish behaviour they had become synonymous with in recent years. But Elgar feels \'it\'s not going to last very long\'.
