that year that formed the first-ever WTA Tour calendar. The tournament became the Virginia Slims of California in 1974 and its venue moved around the San Francisco area before settling at the Oakland Coliseum between 1979 and 1996. The tournament has continued to grow and grow since moving to Standford, with Stanford Director of Tennis Dick Gould telling the local Mercury News website: It's been a great marriage and just about every great player from the last 14 years has played here. It's been a really great thing for not only Stanford, but for the Northern California community in general. Australian Samantha Stosur is the top seed for the 2010 version, although injury means that the Williams sisters -- who both hail from the area -- will not be in action.
