The Sharks remain top of the Currie Cup standings after maintaining their winning start to the season with a thrilling 26-19 victory over the Bulls.
Teenage fullback Curwin Bosch was the hero for the hosts at Kings Park, scoring one of his side's two tries and adding 16 points with the boot to steer Robert du Preez's side to a fourth successive success.
Jamba Ulengo drew first blood for the Bulls by finding the line after nine minutes, but the visitors then lost flanker Ruan Steenkamp to a yellow card for a tip-tackle.
Ruan Botha duly bagged the Sharks' first try and Bosch's accuracy off the tee took them out to a 16-10 half-time lead.
The Bulls could only manage three penalties from Tian Schoeman after the break, while Bosch converted his own try and added a penalty.
In Port Elizabeth, meanwhile, it was centre Huw Jones who captured all the headlines as he ran in a hat-trick of tries in Western Province's 36-6 win over hosts Eastern Province Kings.
Both sides went into the game seeking their first victory of the new season, but the result was never really in doubt once Leolin Zas found the line for the visitors after 11 minutes.
Jones and Sikhumbuzo Notshe then took full advantage of the Kings losing two men to yellow cards by crossing for further tries before the break.
Scrumhalf Jano Vermaak added Western Province's fourth five-pointer midway through the second half before Jones completed his hat-trick with two late scores.
The result moves Western Province up to sixth, while Eastern Province remain rooted to the bottom of the table having now conceded 113 points in three games.
