The Sharks emerged 12-3 victors over the Scarlets in a low-scoring, scrappy affair that brought the curtain down on the regular United Rugby Championship campaign.
With neither side managing a try, it was a match dictated more by discipline and territory than attacking flair.
All of the Sharks' points came through the boot, as they slotted four penalties in the 38th, 53rd, 68th, and final minute.
Despite dominating both possession and territory, the Durban-based side struggled to convert pressure into meaningful chances, hampered by repeated handling errors and a slew of conceded penalties.
Even a quadruple substitution in the 55th minute failed to inject the spark they needed.
The Scarlets, meanwhile, offered little in attack. Their only points came from a well-taken drop-goal by Sam Costelow on the stroke of half-time, levelling the scores at 3-3.
Despite a valiant defensive effort, including a standout performance from No 8 Taine Plumtree - son of Sharks head coach John Plumtree - the Welsh outfit could not find a way through.
The second half followed a familiar pattern, with both sides lacking fluidity and making basic mistakes.
As frustrations mounted, the Sharks remained composed enough to take their chances from the tee, slowly pulling away.
It was a disappointing end to the league phase for the Scarlets, who failed to capitalise on their rare visits to the Sharks' 22.
For the hosts, the win was more about grinding out a result than showcasing their attacking capabilities.
