Ronaldo Mulitalo has a double, and the Sharks will head to the sheds ahead at half-time.
Just when it looked like the Roosters might score before the break, Sam Walker coughs up the ball, and it falls right into the hands of Jesse Ramien.
Ramien and Billy Burns take off down the right edge, and even when the Roosters are able to contain them on the right, they’re caught for numbers on the left.
Braydon Trindall sends a Harbour Bridge pass out to Mulitalo on the wing, and Nicho Hynes converts to give his team an eight-point lead at the break.
Half-time: Sharks 12, Roosters 4
