The goal of every professional tennis player is to win all the Grand Slam tournaments, which consist of the Australian Open, the French Open, the U.S. Open, and Wimbledon. These tournaments are considered the “Quadruple Crown” of tennis, and winning these is the goal of all professional tennis players, as well as the amateur tennis players who wish to go pro some day. When a professional tennis player wins all the Grand Slam tournaments in one season, it is simply called “a Grand Slam.”
For professional male tennis players, the ATP, or Association of Tennis Professionals, is an international circuit for tournaments. The ATP Tour consists of men’s tennis tournament series such as the Masters Series, International Tournament series, International Tournament Series Gold, the Challenger Series, the Delta Tour, and the World Team Cup. The WTA, more officially known as the Sony Ericsson Women’s Tennis Association, is what governs professional women’s tennis. The WTA hosts such tournament series as the women’s Australian Open, the Toray Pan Pacific Open, the Sony Ericsson Open, and the Family Circle Cup.
Amateur tennis tournaments can be held through schools, leagues, or associations. School tennis tournaments can be very big affairs, especially when you get to the high school and college levels. They can be held within cities, states, or nationwide. League tournaments can be held within the individual leagues and among different leagues. There are a wide variety of junior tournaments, which are usually for kids between the ages of 7 and 18, and senior tournaments for anyone over 18.
