Stormers grind out win in Buenos Aires
The match was not the greatest as both teams were unable to score any points in the second half
Missing kickable shots at goal cost Argentina's Jaguares dearly as they suffered a second successive Super Rugby home defeat.
Leading 2015 World Cup points scorer Nicolas Sanchez fluffed two relatively simple chances to add to his early penalty against the South African visitors.
The flyhalf missed the conversion of a try by centre Jeronimo de la Fuente at the end of a first half in which all 21 points were scored before a large crowd at Estadio Jose Amalfitani in Buenos Aires.
Sanchez failed again on the hour as a slightly more difficult penalty attempt drifted wide to groans from supporters.
Replacement kicker Santiago Gonzalez Iglesias tried to trim the five-point gap with a more challenging attempt, but he was also off target.
Stormers flyhalf Kurt Coleman had slotted two penalties as the Cape side were dominating the set pieces, especially the scrums against a strong looking Jaguares pack.
Sanchez had replied with a penalty himself before the Argentine playmaker was sin-binned midway through the opening half for a professional foul.
The South Africans took advantage of the numerical advantage within two minutes as fullback Cheslin Kolbe jinked his way past several would-be tacklers to dot down.
Coleman converted for a deserved 13-3 lead. Once back to full strength, the hosts finished the opening half strongly and De la Fuente went over in additional time.
Jaguares must wait at least until April 30 to celebrate a first home Super Rugby triumph after also committing many handling errors and lacking composure when within sight of the Stormers' tryline.
Jaguares began life as a Super Rugby team by beating the Cheetahs and losing narrowly to the Sharks in South Africa.
After failing against the defensively strong Stormers, and also losing narrowly to the visiting Chiefs from New Zealand last weekend, they embark on a four-match tour.
Stormers have a bye next weekend, then host the Sunwolves in Cape Town.
The victory increased their lead in the Africa Conference One standings to eight points ahead of three-time Super Rugby champions, the Bulls.
Man of the match: Eben Etzebeth made some crucial steals in the line-outs, while Cheslin Kolbe had some good touches with ball in hand. However, the award goes to co-captain Frans Malherbe who had a powerful showing in the scrums and was also a monster in defence.
