Women's Tennis Association

WTA stands for Women's Tennis Association, and is also known as the WTA Tour, and is to women's tennis what the ATP is to men's tennis. In 2005 the WTA changed its name into The Sony Ericsson WTA Tour.

The Women's Tennis Association was begun in Houston, Texas when the inaugural Virginia Slims event was won on 23 September 1970. Billie Jean King was a major figure in the early days of the WTA.

Ranking

The organization releases a weekly ranking of the players's performance in the tour. Players' ranking points are counted how they fare on individual rounds of a tournament (round points) as well as the rank of the players they defeat (quality points). The following table gives the distribution of "round points":
