The Bulls are the only South African side to win the Super 14
South Africa's Bulls stormed to their second Super 14 title in three years with a breathtaking 61-17 victory over New Zealand's Waikato Chiefs.
It was the biggest margin of victory in a final in the event's 14-year history.
The Bulls, with a large Springbok contingent, scored eight tries including 27 unanswered points in the space of 20 first-half minutes.
Fly-half Morne Steyn kicked 19 points to press his claims for a place in the South Africa side to face the Lions.
The Chiefs silenced the 52,000-strong crowd at Loftus Versfeld in Pretoria when they opened the scoring in the seventh minute with a try by right wing Lelia Masaga.
But scrum-half Fourie du Preez launched his side's eight-try stampede with a brace in a three-minute span.
Winger Bryan Habana then scored twice from long-range, one from an interception, and with Steyn's boot as straight as an arrow, the Bulls had victory secured by the break.
The Chiefs got back to within 20 points at 37-17, but Bulls skipper Victor Matfield, centre Wynand Olivier, number eight Pierre Spies and replacement lock Danie Rossouw added tries.
