Cape Town - The Waratahs emerged 37-16 winners in an error-ridden Australian derby against the Reds on Saturday.
The match took place at the Sydney Cricket Ground, but that was about the only attraction in what was an otherwise forgettable contest that saw the Waratahs dominate.
Both sides made countless mistakes - in open play and at set piece - but it was the hosts who did enough to get the victory.
The Waratahs took a 13-6 lead into half-time before two second-half scores from left wing Taqele Naiyaravoro made the game safe.
The result sees the men from Sydney move to the top of the Australian Conference, ahead of the Rebels who were shocked at home by the Jaguares earlier in the day.
The Reds, meanwhile, stay fourth in the Conference with just three wins from seven.
