After suffering two back-to-back losses in their previous outings, the KwaZulu-Natalians bounced back to beat a determined home side in a tough tussle played in excellent early evening conditions in the Northern Cape.
The Cell C Sharks went into the halftime break with a four point advantage following a converted try and a penalty goal, while the home side replied with two successful penalty kicks.
Cell C Sharks hooker Fez Mbatha grabbed the only try of the match when he dotted down after a lineout maul, while Joaquin Diaz Bonilla added the extras. The Cell C Sharks pivot also hit the target later on with an easy penalty goal attempt.
The Argentinean Test player scored the only points of the second half when he succeeded with a late penalty goal from under the posts take the final score to 13-6 for the visiting team.
Flyhalf George Whitehead kept the hosts within striking distance with his two first-half penalty goals, however, the Peacock Blues would be disappointed with the several spilled opportunities especially in the opening half.
They launched several attacks on the visiting try-line, but each time they came away empty handed. It was as a result of committing crucial errors when more patience were needed and also solid defence by the black and white jerseys.
The second half was a real arm wrestle, with neither side able to gain the outright advantage. However, Bonilla had the final say when he easily kicked over his 76th minute goal attempt to seal a tightly contested match.
Windhoek Draught Griquas 6 (6) - Penalty goals: George Whitehead (2).
Cell C Sharks 13 (6) - Try: Fez Mbatha. Conversion: Joaquin Diaz Bonilla. Penalty goals: Bonilla (2).
