Amateur, college, and professional tennis players are ranked according to a point system which is based on the number of tournaments they play, which tournaments they play (i.e., different venues have different points associated with them), and how well they play in a given match. For professional tennis players, the ATP (men's tour) and WTA (women's tour) are the governing bodies for player rankings; refer to the links, below, for up-to-date professional player rankings (n.b., the websites may change if/when the sponsorships change).
