The Argentina-based Jaguares have secured a third Super Rugby victory in their debut season, beating the Bulls 29-11 in Buenos Aires.
It was a morale-boosting win for the Jaguares, who had 13 players in the Argentina team beaten 27-0 by France last weekend.
Hooker Agustin Creevy led the way with two tries after flanker Pablo Matera was the first to go over in the 13th minute, while five-eighth Nicolas Sanchez kicked 14 points.
The Pretoria-based Bulls had to wait an hour for their try when replacement halfback Piet van Zyl took a quick tap and scampered over.
