Andrew McDonald says Marnus Labuschagne's position at No.3 is safe despite a lean trot, as Australia prepare to give their top six batters an extended run in their slots in Test cricket.
Labuschagne, who made 19 runs at an average of 6.33 in the 1-1 series draw with West Indies, has made 1005 runs in his past 35 innings at an average of 33.5, with just one Test century.
