Only SA teams stand between Jaguares and play-offs
The Jaguares face the Sharks in Buenos Aires in Round 15 before welcoming the Stormers after the June international break.
Mario Ledesma's side will finish the regular season in South Africa with matches against the Bulls [July 7] at Loftus Versfeld and the Sharks [July 14] at Kings Park.
"Not only do we have to try and win all these games, we must seek some more bonus points after getting our first of the season when beating Bulls," said Petti after his team thrashed the Bulls 54-24 in Buenos Aires.
Their win over the Bulls continued a remarkable turnaround for the Jaguares.
It was the Jaguares' fifth consecutive victory after winning only two of their first seven matches to go seventh in the combined standings with the top eight qualifying for the finals.
