But coach Mick Potter sprang a slight surprise by switching Sia Soliola to the pack, freeing him to recall fit-again Jonny Lomax onthewing and slip Meli inside to centre.

Mike Phillips was immediately onthe centre's inside shoulder and the final act was supplied by Walker, as the Scotland left wing appeared onthe other flank to switch the angle of attack again.
