Tennis ---Direction of Shot anticipation?

The best way would be to watch the way they set theirselves up-if you notice pros on t.v., you can tell they almost always go for the shot where there is space on the court. Notice their stances-whether they open themselves more to hit a down the line shot or if they rotate more to hit that cross-court forehand. for their serves, you have to learn how to find a pattern-maybe they like to hit their 1st serves wide and their 2nd down the middle. Other than that, id watch the serve right about when they hit the ball. Be on ur feet and notice how they pronate-this should tell you the direction of the ball. Notice their grip and how they hold their racket-this could give you a clue about how the spin and such should be on their next hit. If you really look at the pros on t.v., this should help you the most. Then apply some of the skills on the court. Afterall, practice makes perfect!
