Cape Town - The Kings have shocked the Waratahs for only their third ever overseas Vodacom Super Rugby victory on Friday.

The Kings scored four tries through prop Justin Forwood, fullback Masixole Banda, hooker Michael Willemse and were awarded a late seven-point penalty try. Flyhalf Lionel Cronje added two conversions.
The Waratahs, the 2014 champions, replied with four tries of their own by wings Taqele Naiyaravoro (2) and Cam Clark and centre Rob Horne, while flyhalf Bernard Foley was on target with two conversions.
The Kings, playing with their Super Rugby future under of a cloud of uncertainty, picked up four points for their victory, but remained bottom of the African Conference 2.
