Souths spent the opening minutes of the first half in their opponent’s half asking questions early on.
Surviving the early attacks, Royals made their way out of danger and into South’s territory.
The boys in blue nearly hit the lead had Joel Amos held onto the ball after barging over the line carrying three defenders over with him.
But Souths continue to keep the pressure on and this turned into points when Sunny Wabo was put into a gap to dance his way to the try line and score under the posts.
Haston Sisi converted the try to take Souths to a 6-0 lead going into half-time.
The Royals boys were their own worst enemy dropping the ball on three occasions close to the line in the second half.
A mistake in their own half led to them conceding more points as Souths spread the ball out wide before sending in winger Zetro Ben to fly over.
Good defence from Souths and poor ball control from Royals ensured Souths went on to win the round nine match.
