Tennis, originally called lawn tennis, is believed to have been invented
by the British army officer Major
Walter Clopton Wingfield in 1873. It was supposedly modeled after
English court tennis, squash racquets and badminton. It has since become
a widely played game both professionally and on amateur courts worldwide.
Tennis is a sport played on a court with a racket and a ball. It can be played by two (as in singles) or four (as in doubles) indoors or outdoors. Courts are divided by a net and marked with two sets of lines, one for singles and one for doubles play. The court is 78 feet long and 27 feet wide for a singles game. When playing doubles, the width boundaries are 36 feet apart. The court may be grass, clay, asphalt, concrete, wood, turf, or composite. The ball is made of hollow inflated rubber 2.5 to 2.6 inches in diameter. The rubber is covered with a wool fabric. It is usually yellow, although other colors may be used. Tennis rackets vary in size and shape, although the maximum tournament length is 29 inches and the maximum width is 12.5 inches. The racket head is no more than 15.5 inches and 11.5 inches wide. It is strung with thin overlapping cords of gut, nylon, or other materials. Originally made of wood, most current rackets are now made of stronger and lighter materials such as aluminum, graphite, and carbon fiber. The handle features a rubber or leather grip and vibration-dampening technology. Clothing is usually lightweight shirts, shorts, and short skirts. Shoes with nonskid rubber soles are also worn.
Players play a "set" of games. The winner of the set must win six games, and they must lead by at least two games. If a set is tied at 5-5, at least 7 game wins are required to win the set. Matches are usually the best two out of three or best three out of five sets. Most tournaments employ officials to referee the games. The chair umpire is the head official and he may preside over a number of line judges who determine the viability of shots and serves. There may also be a net-cord judge to determine if a ball has touched the net, and a foot-fault judge who watched for bodily infractions of boundaries.
The first professional tennis game was played in 1926. Charles C. Pyle was an American promoter who organized the paid traveling tour. Professional players were barred from these tournaments, but by 1968 most tournaments were open to professional as well as amateur players. "Grand-slam" tournaments include the Australian Open in Melbourne, the French Open in Paris, Wimbledon in London, and the US Open in New York City. Winning all four major grand slam tournaments in one year is the most coveted achievement in tennis.
