Mar del Plata, Argentina - Both teams are hoping that the weekend Davis Cup final between host Argentina and a Spain missing Rafael Nadal will not erupt in violence or bad behavior from the partisan South American crowd.

Sparks have already flown at the indoor hard court venue when a short circuit caused a minor electrical fire as Juan Del Potro and Argentine teammate Jose Acasuso were training.

While the hitting session was stopped for a few minutes which the flames were brought under control it might take more than a few extinguishers to calm passions when the weekend tie begins with singles on Friday.
