Two tries in the last 20 minutes handed the Jaguares their first win of the new Super Rugby season with a 27-12 victory over the Bulls after a scrappy contest in heavy rain on Saturday.
The Bulls led 12-9 when flyhalf Handre Pollard converted his fourth penalty on the hour mark, but replacement Rodrigo Bruni went over off the catch-and-drive and winger Bautista Delguy scored on the overlap to secure the victory.
The result was a tonic for the Argentines, who lost 25-16 at home to the Lions last weekend, and a disappointment for the visitors, who smashed the Stormers in their opener.
