The visitors got their first points through Pablo Matera.
The second half seemed to bring a Bulls side that were changing their minds and score tries.
The Bulls sent the ball down the backline spreading it wide. They showed fantastic hands in the tackle to open space for Jade Stighling to go over in the corner.
Libbock got two more penalties over with Iglesias getting one over which gave the Bulls 20-10 lead with 10 minutes to go.
It was here were it all ent wrong for the Bulls.
The Jaguares scored two brilliant tries in this time which showed off their brilliant skill in keeping the ball alive. Mottie was the man at the end off both tries to sealed the win for the visitors.
Two yellow cards started it all for the Jaguares when Tim Agaba and Conraad Van Vuuren was send off.
Playing with thirteen men in the last 9 minutes of the match was just too much for a side who left out a few Springboks for this match.
