I am suppose to play a high school tennis match next week at the country club that has clay courts. I thought it was werid that I will be playing on clay since high school matches are always on hard courts, from what I have seen, heard, and played from. From what I know is that it is going to be on green clay. I have never played on clay before. So what should I be expecting, and what should I do that I usualy dont do on a hard court. thanx for help.
