Who wants to watch a sports match until just BEFORE it ends? I don't know if it is because the Tennis Channel sends you programming that is timed so that it does not cover the entire match and Sling just isn't paying attention to their program content. OR if Sling just doesn't have programming that one can follow across different programs when the length of the match needs more time than the original time allotted will allow. User's recommendation: Do not get Sling if your purpose is to watch tennis matches. You will get nothing but frustration.
