What does it mean when a player earns the “#1 ranking?” What is a ranking? There are many answers, ranging from simple to complex. A simple answer is, “A ranking is a way for assessing players’ performances and seeding them in tournaments.” This is the purpose of the rankings. A technical answer, for female tennis players, is, “A number, the sum of the points earned in a player’s best eighteen tournaments, where points are awarded according to a system based on the prize money the tournament offers and the quality of the opposition one faces.” This is the method behind the rankings. But the usual answer is, “It’s a way to determine who is the best player.” But “best” can mean a lot of things. The player who is best overall may not be the best on clay. Or may have moved to the top based partly on health (ability to play a full schedule). Some players are more consistent, others streaky. The best player may not have the best winning percentage (in 2000, the player with the best winning percentage wound up #3; in 1998 and 1999, she wound up #2), or the most wins, or the most titles. In fact, the #1 ranking guarantees only one thing: That the player has done what it takes to be #1. Thus the official tennis rankings, while they have great importance to the players (since they determine seeds and tournament admission) are actually just numbers. They do not automatically say who is the best player (whatever “best” means); they simply say who has the highest point total under the WTA rules. To fully understand a player’s game, we need to know much more than her ranking. We need to know she did on each surface. We need to know she fared against other top players. We need to know how many tournaments she won, and how often she suffered a first round defeat. A complete statistical picture of a player will involve a vast array of statistics, and involve many types of data. What follows is an attempt to examine some of these subjects, at least for the top players. It is a statistical exercise, based mostly on the results for the WTA Top Twenty-five, designed to provide more perspective than the WTA’s simple point-counting game. It also offers some miscellaneous statistics of interest. Depending on the statistic, data may be offered based only on the Top Ten, the Top Twenty, or the Top Twenty-Five (usually one of the latter two). It is assumed that the Top 5 in all categories will be on this list, and usually the Top 10. We should add a at least two footnotes: First, this document is based solely on actual Tour events; exhibitions (Fed Cup, Olympics) are not included. This is deliberate and necessary; the WTA should not include these events in their statistics! This is because these events fill their draws by means not based on the WTA rankings. This, in turn, means that they are not valid for statistical comparison. Second, for reasons of time, calculations in this document are based on the results as of the end of the Tour year (November 20, 2000). Challengers are played after this event — notably Cergy Pontoise, which Magdalena Maleeva played in 1999 and Nathalie Déchy may play in 2000. This will affect the year-end 2000 rankings, but cannot be accounted for here. The data in this document has been checked several times against multiple sources. But available records (especially for doubles) are often far from complete. No responsibility is assumed by the author or by the web site for any errors contained in this document, or for the nature or meaning of any statistics presented. The purpose of this document is not to assert opinions. Of course, it is impossible to entirely avoid opinions, since (ahem!) I have some. These opinions perhaps influence which statistics I include. Nonetheless, this abstract exists primarily for the sake of the numbers. If there is commentary, it is intended to explain what the numbers mean or to bring out some especially salient point. WTA Statistical Abstract 2000 ©Robert Waltz Page 3 The only subjective matter I will address in this preface is my feelings about the #1 player. Martina Hingis is the WTA #1, but many have argued on behalf of Venus Williams, as the winner of two Slams. (Curiously, no one has argued recently on behalf of Lindsay Davenport, even though it was Davenport, not Williams, who spent most of 2000 nipping at Hingis’s heels in the rankings, and was #1 for a few weeks.) There is no question that Venus Williams was more effective when she played.
