The Bulls ran in three first-half tries as they completed a hard-fought 23-18 Super Rugby victory over South African rivals the Cheetahs at Loftus Versfeld.
Locks RG Snyman and Jason Jenkins plus flying winger Jamba Ulengo crossed the line for the home side, who led 20-10 at halftime.
But the visitors were always in the game with wing Sergeal Petersen and hooker Torsten van Jaarsveld bagging tries as they dominated second-half possession and territory.
