Halfback Adam Reynolds' kicking game was sharp, reminding NSW coach Laurie Daley of his strengths should the Canterbury halves combination of Trent Hodkinson and Josh Reynolds not go to plan against Queensland on Wednesday night.
The only silver lining for the battling Sharks was the sight of Andrew Fifita warming up with teammates in a sign the Origin and Test powerhouse could be in contention for an early NRL return in two weeks' time after the bye.
In a low-scoring game despite the dry conditions, a barnstorming first-half try to Souths lock Sam Burgess was enough to propel the Rabbitohs towards the two points.
The result was put beyond doubt in the 56th minute when winger Joel Reddy came in-field to pop a smart offload before Dylan Walker burst through a hole to set up his centre partner Kirisome Auva'a for a 30-metre dash to the line.
Reserve hooker Cameron McInnes burrowed over from dummy half seven minutes later.Cronulla's night and dismal season was summed up early in the second half when halfback Jeff Robson raced downfield on a 40m first-tackle run, before his loose offload to fullback Michael Gordon was turned back over.
Gordon always looks likely from the back, but halves Robson and Daniel Holdsworth struggled to spark the attack - their mis-firing kicking game a major concern.
Morris ran through a banner pre-match, with his family on hand to honour the four-club veteran for becoming the 19th member of the NRL's 300-game club.
