1988 Virginia Slims World Championship Series
The 1988 Virginia Slims World Championship Series was the 16th elite tour for professional women's tennis of the Women's International Tennis Association for the 1988 season. The 1988 Virginia Slims World Championship Series included the four Grand Slam tournaments, the WITA Tour Championships and the WTA Category 1-5 events. ITF tournaments were not part of the WTA Tour, although they award points for the WTA World Ranking.
The tour was governed by the Women's International Professional Tennis Council, a cooperation between WITA, ITF and recognized tournaments. Philip Morris sponsored the tour under its
Virginia Slims brand.
Steffi Graf became the first singles player in history to win the Golden Slam by taking the Australian Open, French Open, Wimbledon and US Open singles titles, along with the Olympic gold medal. Graf's defeat by Pam Shriver in the semifinals of the Virginia Slims Championships deprived her of a Super Slam.
