The damage was done over the opening 40 minutes when the Sharks ran in three tries to hold a 20-0 lead at the break, Gordon's opener followed by a individual effort from Carney who dummied and danced past a pair of defenders.
The Panthers seemed out of ideas other than for Luke Walsh to kick to the corners, Cronulla making them pay on the stroke of halftime when Sosaia Feki crossed out wide.
There was little urgency in Penrith after the break when Gordon grubbered ahead to score from ten metres out, the game as good as over at 26-0.
Matt Moylan was denied a try for Penrith when millimetres offside, James Roberts scoring minutes later when he showed better timing to run down a Moylan grubber.
Lewis Brown butchered a try when he bounced a ball to end any hopes of a thrilling comeback, Roberts' second 12 minutes from time merely softening the scoreline.
Cronulla celebrated with two late tries including a second for Feki on the bell when he brilliantly chased down a Carney chip kick just inside the deadball line.
