Professional tennis players seem to know which balls immediately they are going to use for service by just holding them in one hand. What is the basis for their decision. To the ordinary person it seems that all the balls look the same.

I like to play tennis but it’s so hard to keep the balls around. I am not really good at playing it so the balls often fly over the fense or to the other side of the court. I play at a local park where a large tennis courts are placed. I am thiknig of some kind of mesh that can be put accorss from one side to the other…what do you think you can use for it?

I am a definite tennis player, and its always a pain to pick up the balls after tennis practice. I’ve seen my coach and some other players use their racket and their foot to pop the tennis ball off the ground. Can anyone tell me the basics on how to do this?
