Springbok No 8 Ryan Kankowski ran in the third try that clinched a second successive Super 14 for the Sharks over domestic opposition.
Having seen off the Stormers in Cape Town a week earlier, South Africa’s top provincial outfit beat the resurgent Lions 25-10 on home soil in Durban.
As well as Kankowski’s superb individual effort just after the hour mark, the Sharks had tries from prop Deon Carstens and wing JP Pietersen in their scoreline as they made it two from two at the start of their Super 14 campaign.
World Cup winning skipper John Smit once again started the game at hooker ahead of Bismarck du Plessis and Springbok coach Peter de Villiers will have been impressed by the overall quality of the game and the performances of those players vying for places against the British & Irish Lions this summer.
There was a third try in two Super 14 games from Lions wing Ashwin Willemse, who returned to Johannesburg from Biarritz recently, but the Lions were never able to hold onto the home side after the break.
