Todd Lowrie's Newcastle Knights Jersey Flegg side has sent a message to the rest of the 20s competition following a determined 24-18 win over Cronulla.
Following a two-week break, the Knights are running into the finals with some serious moment, sitting on top of the ladder.
While it was the Sharks who struck after six minutes through Cruz Topai-Aveai, the Knights returned serve eight minutes later when Elijah Rasiga flew over for the first of two-tries.
Starting in the no.9, Tom Starling posed questions of the Sharks defence from dummy half, as Hayden
Loughrey steered the ship alongside birthday boy Phoenix Crossland who turned 18.

The Sharks pushed ahead through Jackson Ferris who secured a first half double before Ben Talty reduced the margin at the 20-minute mark.
Rasiga crossed again for his second before the speed of Matt Cooper was too much for the Cronulla defence.
The fullback scored just three minutes from halftime to reclaim the lead.
Ahead by two-points at the break, it took the Knights until the 74th minute to seal victory when Ofa Manuofetoa barged over.
