The Jaguares ran in five tries to thrash the Sharks 34-7 in Buenos Aires on Saturday night to clinch the South African Super Rugby conference in style.
The Sharks were in for a long night from early on in the game, as Sebastian Cancelliere scored the first of his two tries after just three minutes.
Classy fullback Emiliano Boffelli ran in a second, and despite the Argentinians missing a few shots at goal, they still led 12-0 at halftime.
But things got even worse for the under-fire Durbanites in the second half, as Cancelliere and Boffelli added further tries, while Santiago Carreras also got on to the scoreboard.
The Sharks grabbed a consolation through centre André Esterhuizen, but it was a night to forget for the visitors.
