After the Ducks tied the score at five in the eighth inning, the game would progress another six frames before another run would cross the plate.
Both clubs put up a two-spot in the 15th inning before Camden would score the game-winning run in the 18th, six hours and 20 minutes after the game began.
The 18-inning contest was the longest game played in the Atlantic League's history in both innings and time elapsed.
During the game, fielders Jason Conti, Richie Barrett and Matt Demarco took the hill for the Riversharks.
Conti picked up the win in his first career appearance on the hill after hurling three scoreless innings of relief.
