The home team started off strongly as Ederies Arendse (wing) dotted down in the ninth minute for a converted try by George Whitehead (flyhalf), but the Vodacom Blue Bulls drew level minutes later as former Springbok wing, Travis Ismaiel, scored. Fiela Boshoff (flyhalf) added the extras.
The visitors' try seemed to light a fire in the bellies of the Kimberley side as they scored two more tries in the first half courtesy of AJ le Roux (hooker) and Andre Swarts (inside centre) in the 21st and 27th minute respectively.
Whitehead's converted both tries to hand the Peacock Blues a 21-7 lead which remained unchanged until the half-time hooter.
The men from Pretoria ensured that they were the first to score when the match resumed as JT Jackson (inside centre) added his name to the try scoring list and Boshoff made no mistake with the extras.
Jackson then closed the gap on the scoreboard with a penalty goal four minutes later, but the Vodacom Blue Bulls' strong start to the second half came to an abrupt end in 55th minute as Sias Koen (flank) smashed his way over the whitewash to score, which was duly converted by Whitehead.
Whitehead, who had a flawless game with the boot, stretched the home team's lead with a penalty goal.
Arendse bagged his brace with 14 minutes left on the clock while Whitehead's conversion was once again the final points scored in the match as the Tafel Lager Griquas emerged 38-17 victors against the Vodacom Blue Bulls and kept their unbeaten streak in check.
