The Roosters overwhelmed the Sharks in Perth, resulting in a 34-22 defeat for Cronulla, who failed to score in the second half despite an earlier threat.
Statistics were in favor of the Roosters, as they maintained 55% possession and led the penalty count with 8-4.
Sharks' players Blayke Brailey and Billy Burns are under scrutiny for potential infringements following reports of a hip drop and a high tackle.
The match commenced with Roosters' captain James Tedesco slicing through the defense, though he was stopped from behind during a passing play with Sam Walker.
Shortly after, the Sharks' defense halted Mark Nawaqanitawase, allowing them time to reset their line.
An error later gifted Sione Katoa an opportunity, leading to Cronulla's first points as Jesse Colquhoun scored his second try of the season.
Just four minutes later, a deflected pass from Nicho Hynes set up Mawene Hiroti for another try, marking his third in Perth.
The Sharks extended their lead when Braydon Trindall capitalized on a gap, showcasing Brailey's excellent setup.
However, the Roosters regained momentum as Walker assisted Hugo Savala, who scored under the posts.
