Last Summer in our Local USTA League we encountered a certain team twice, where when our match became tied 2-2 and only had one singles match left to be completed, gathered together with their friends and family to form a huge cheering section. Ive seen this rarely from another team, but the diffrence in this case was not only did they cheer loudly when their player did something good, they would also cheer loudly when my player did something bad, like hit the ball into the net. Ive learned from watching tennis at other events that this is just a very low and classless thing to do, but some of these guys are new to tennis and probally think they are at a basketball game. This is a non-officiated match so there wasnt much to do. Myself and my team doesnt cheer for each other ourselves (unless there is a really great point played out) because it's a distraction even if it's positive. In the second match they were also openly and loudly questioning my players line calls. (like if he called a ball out one of them would scream "WHAT!!??") Which I do believe is going over the line somewhat since they have no part in that match. Is there anything out there that makes this sort of behavior wrong? Ive seen rules on college tennis about rowdy fans who might do the same thing, but Im not sure how they apply to a non-officiated USTA League match.
