The Rabbitohs have smashed the Knights to make a huge statement in the Nines finals, scoring 30 unanswered points after conceding a try off the opening play of the game and booking a semi-final against the Eels.
The Knights exploded out of the blocks when Tyrone Roberts spread the ball to speedster Jake Mamo, who backed up his opening-game hat-trick by burning past Adam Reynolds to streak the length of the field and score next to the posts right from the kick-off.
They handed the lead straight back though, a risky offload on their own tryline by Dane Gagai going straight to the hand of Chris McQueen who scored an easy bonus zone try for Souths.
Gagai responded with a 60-metre surge downfield to make partial amends but the Knights weren't able to capitalise, Nathan Ross going close but getting held up over the line.
Retired Rabbitoh Matt King's weekend got even better when he scored another try following a classy pass from young centre Aaron Gray to make it 11-6.
Reynolds managed to snake his restart across the dead ball line to put the Knights back under pressure, but they were good enough to defend back-to-back sets. However a penalty right on half-time handed Reynolds a chance for a drop-goal from in front, which he happily accepted for another two points.
When Roberts wrecked a good run early in the second half by offloading straight to Ben Lowe, the Rabbitohs went on the attack and one play later Lowe produced a monstrous fend on Nathan Ross, opening the way for him to stretch the lead to 19-6.
The Rabbitohs kept the pressure on and cracked the game open when big George Burgess swooped on a loose ball to charge over in the bonus zone and put the result beyond doubt at 26-6. Joel Reddy barged over three seconds before full-time and Matt King produced a comically bad conversion attempt after the siren to leave the final score at 30-6.
