It would be easy to criticise the expanded World Club Series after Souths’ victory confirmed a three nil series whitewash for the NRL.
But Michael Maguire’s team were relentless and deserved their seven try victory over a spirited St Helens side.
It was a case of deja vu as the Australian side struck first, scoring through Glenn Stewart inside two minutes from Adam Reynolds’ grubber.
Souths demonstrated their attacking prowess to score through Inglis for an 18-0 lead but their fourth try was the result of a freak bounce which landed perfectly for Joel Reddy.
Keiron Cunningham’s side ended the half on the front foot but without any points as Percival spilled the ball under more intense pressure.
Substitute Chris McQueen added his side’s sixth try of the evening before Reddy grabbed his second in a thoroughly dominant display.
Reynolds rubbed salt into the wounds with a drop goal in the 78th minute for 39-0, the widest ever World Club Challenge winning margin.
