My favorite athletic shorts are UA shorts that unfortunately don't always have pockets. I also play tennis a lot and setting a ball behind you on the ground can be dangerous. Having this on your waistband is fairly unnoticeable when playing. I play fairly aggressively and haven't had the ball fall out of the holder. In the end, I definitely prefer to simply wear shorts with pockets, although this is a great alternative to have.
