Tennis:

Tennis is a racquet sport played between two players (singles) or between two teams of two players each (doubles). Each player uses a strung racquet to strike a hollow rubber ball covered with felt (most of the time Optic Yellow,[1] but can be any color or even two-tone) over a net into the opponent's court.
The modern game of tennis originated in the United Kingdom in the late 19th century as "lawn tennis" and had heavy connections to the ancient game of real tennis. After its creation, tennis spread throughout the upper-class English-speaking population before spreading around the world. Tennis is an Olympic sport and is played at all levels of society at all ages. The sport can be played by anyone who can hold a racket, including people in wheelchairs. In the United States, there is a collegiate circuit organized by the National Collegiate Athletics Association.
Except for the adoption of the tie-breaker in the 1970s, the rules of tennis have changed very little since the 1890s. A recent addition to professional tennis has been the adoption of "instant replay" technology coupled with a point challenge system, which allows a player to challenge the official call of a point.
Along with its millions of players, millions of people worldwide follow tennis as a spectator sport, especially the four Grand Slam tournaments (sometimes referred to as the "majors"): Australian Open, Roland Garros (French Open), Wimbledon (UK), and the U.S. Open.

History:

Tennis as the modern sport can be dated to two separate roots. Between 1859 and 1865, Major Harry Gem and his friend Augurio Perera developed a game that combined elements of rackets similar to the game of Poona or Badminton many British soldiers brought from being stationed in India and the Basque ball game pelota, which they played on Perera's croquet lawn in Birmingham, England.[2][3] In 1872, along with two local doctors, they founded the world's first tennis club in Leamington Spa.[4] The Courier of 23 July 1884 recorded one of the first tennis tournaments, held in the grounds of Shrubland Hall.[5]
In December 1873, Major Walter Clopton Wingfield designed a similar game — which he called sphairistike (Greek σφάίρίστική, skill at playing at ball), and was soon known simply as "sticky" — for the amusement of his guests at a garden party on his estate of Nantclwyd, in Llanelidan, Wales.[6] He based the game on the newer sport of outdoor tennis or real tennis. According to most tennis historians, modern tennis terminology also derives from this period, as Wingfield borrowed both the name and much of the French vocabulary of real tennis and applied them to his new game.

Lawn tennis in the U.S., 1887
The first championships at Wimbledon, in London were played in 1877.[7] On May 21, 1881, the United States National Lawn Tennis Association (now the United States Tennis Association) was formed to standardize the rules and organize competitions.[8] The U.S. National Men's Singles Championship, now the U.S. Open, was first held in 1881 at Newport, Rhode Island.[9] The U.S. National Women's Singles Championships were first held in 1887.[10] Tennis was also popular in France, where the French Open dates to 1891.[11] Thus, Wimbledon, the U.S. Open, the French Open, and the Australian Open (dating to 1905) became and have remained the most prestigious events in tennis.[7][12] Together these four events are called the Grand Slam (a term borrowed from bridge).[13] The comprehensive International Lawn Tennis Federation rules promulgated in 1924 have remained remarkably stable in the ensuing eighty years, the one major change being the addition of the tie-breaker system designed by James Van Alen.[14] The Davis Cup, an annual competition between national teams, dates to 1900.[15]
In 1926, promoter C.C. Pyle established the first professional tennis tour with a group of American and French tennis players playing exhibition matches to paying audiences.[12][16] The most notable of these early professionals were the American Vinnie Richards and the Frenchwoman Suzanne Lenglen.[12][17] Once a player turned pro he or she could not compete in the major (amateur) tournaments.[12]
In 1968, commercial pressures and rumors of some amateurs taking money under the table led to the abandonment of this distinction, inaugurating the open era, in which all players could compete in all tournaments, and top players were able to make their living from tennis.[18] With the beginning of the open era, the establishment of an international professional tennis circuit, and revenues from the sale of television rights, tennis's popularity has spread worldwide, and the sport has shed its upper/middle-class English-speaking image[19] (although it is acknowleged that this stereotype still exists).[19][20][21]
In 1954, Van Alen founded the International Tennis Hall of Fame, a non-profit museum in Newport, Rhode Island.[22] The building contains a large collection of tennis memorabilia as well as a hall of fame honoring prominent members and tennis players from all over the world. Each year, a grass-court tournament and an induction ceremony honoring new Hall of Fame members are hosted on its grounds.

[edit] Manner of play
For individual terms see: Tennis terminology

[edit] The court
Main article: Tennis court

The dimensions of a tennis court, in metric units. (See imperial version).

Two players before a serve.
Tennis is played on a rectangular, flat surface, usually grass, clay, or a hardcourt of concrete and/or asphalt. The court is 78 feet (23.77 m) long, and its width is 27 feet (8.23 m) for singles matches and 36 ft (10.97 m) for doubles matches.[23] Additional clear space around the court is required in order for players to reach overrun balls. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is 3 feet 6 inches (1.07 m) high at the posts and 3 feet (91.4 cm) high in the center.[23]
The design of the lawn tennis court has undergone much development. It was Major Walter Clopton Wingfield who, in 1873, designed a court approximate to the current one for his stické tennis (sphairistike). This template was modified in 1875 to the court shape that exists today; the markings homogeneous with Wingfield's design, with the hourglass shape of his court changed to a more linear framework.[24]

[edit] Lines
The lines that delineate the width of the court are called the baseline (furthest back) and the service line (middle of the court). The short mark in the center of each baseline is referred to as either the hash mark or the center mark. The outermost lines that make up the length are both called the doubles sideline. These are the boundaries used when doubles is being played. The area between the doubles sideline and the lines next to them is called the doubles alley, which is considered playable in doubles play. These lines next to the doubles sideline are the singles sidelines, and used as boundaries in singles play. The line that runs across the center of a player's side of the court is called the service line because the serve must be delivered into the area between the service line and the net on the receiving side. Despite its name, this is not where a player legally stands when making a serve. The line dividing the service line in two is called the center line or center service line. The boxes this center line creates are called the service boxes; depending on a player's position, he will have to hit the ball into one of these when serving. A ball is out only if none of it has hit the line upon its first bounce. All the lines are required to be 2 inches (51 mm) in width. The baseline can be up to 5 inches (130 mm) wide if so desired.

[edit] Play of a single point
Main article: Point (tennis)
The players (or teams) start on opposite sides of the net. One player is designated the server, and the opposing player, or in doubles one of the opposing players, is the receiver. Service alternates between the two halves of the court. For each point, the server starts behind his baseline, between the center mark and the sideline. The receiver may start anywhere on their side of the net. When the receiver is ready, the server will serve, although the receiver must play to the pace of the server.
In a legal service, the ball travels over the net (without touching it) and into the diagonally opposite service box. If the ball hits the net but lands in the service box, this is a let or net service, which is void, and the server gets to retake that serve. The player can serve any number of let services in a point and they are always treated as voids and not as faults. Net services are somewhat unusual at recreational level and frequent at professional level. However, placing more than one let service in a single point takes a considerable amount of skill or luck. If the first service is otherwise faulty in any way, wide, long or not over the net, the serving player has a second attempt at service. There is also a "foot fault," which occurs when a player's foot touches the baseline or an extension of the center mark[25] before the ball is hit. If the second service is also faulty, this is a double fault, and the receiver wins the point. However, if the serve is in, it is considered a legal service.
A legal service starts a rally, in which the players alternate hitting the ball across the net. A legal return consists of the player or team hitting the ball exactly once before it has bounced twice or hit any fixtures except the net, provided that it still falls in the server's court. The ball then travels back over the net and bounces in the court on the opposite side. The first player or team to fail to make a legal return loses the point.

[edit] Scoring
Main article: Tennis score
A tennis match comprises a number of sets, typically three for both men's and women's matches, the exception being at the major events (Wimbledon and the Australian, French and US Opens) where the men play best of five sets.[26] A set consists of a number of games, and games, in turn, consist of points.
A game consists of a sequence of points played with the same player serving. A game is won by the first player to have won at least four points in total and at least two points more than his opponent. The running score of each game is described in a manner particular to tennis: scores of zero to three points are described as "love" (or zero), "fifteen," "thirty," and "forty" respectively. (See the main article Tennis score for the origin of these words as used in tennis.) If at least three points have been scored by each player, and the scores are equal, the score is "deuce". If at least three points have been scored by each side and a player has one more point than his opponent, the score of the game is "advantage" for the player in the lead. During informal games, "advantage" can also be called "ad in" or "ad out", depending on whether the serving player or receiving player is ahead, respectively.
In tournament play, the chair umpire calls the point count (e.g., "fifteen-love") after each point. The score of a tennis match during play is always read with the serving player's score first. After a match, the score is always read with the winning player's score first. At the end of a game, the chair umpire also announces the winner of the game and the overall score.
A game point occurs in tennis whenever the player who is in the lead in the game needs only one more point to win the game. The terminology is extended to sets (set point), matches (match point), and even championships (championship point). For example, if the player who is serving has a score of 40-love, he has a triple game point (triple set point, etc.) as he has three chances to win the game (or set). Game points, set points, and match points are not part of official scoring and are not announced by the chair umpire in tournament play.
A break point occurs if the receiver, not the server, has a game point. It is of importance in professional tennis, since service breaks are rare enough to create a substantial advantage for the receiver in the men's game. The advantage to the server is much less in the women's game, but match analysts like to keep track of service breaks anyway. It may happen that the player who is in the lead in the game has more than one chance to score the winning point, even if his opponent should take the next point(s). For example, if the player who is serving has a score of 15–40, the receiver has a double break point. If the player in the lead wins any of the next two points, that player wins the game. Break points are not announced either.
A set consists of a sequence of games played with service alternating between games, ending when the count of games won meets certain criteria. Typically, a player wins a set when he wins at least six games and at least two games more than his opponent. If one player has won six games, and his opponent five, a further game is played. If the leading player wins the game, he also wins the set (7–5). If the trailing player wins, a tiebreaker is played. A tiebreaker, played under a separate set of rules, allows one player to win one more game and thus the set, to give a final set score of 7–6. Only in the final sets of matches at the Australian Open, the French Open, Wimbledon, Davis Cup, and Fed Cup are tie-breaks not played. In these cases, sets are played indefinitely until one player has a two game lead. A "love" set means that the loser of the set won zero games. For example if the score was 6 to 0, it would be 6 love. (See "tennis terminology" below for names given to unusual endings like the example here.) In tournament play, the chair umpire announces the winner of the set and the overall score.
Matches consist of an odd number of sets, the match winner being the player who wins more than half of the sets. The match ends as soon as this winning condition is met. Some men's matches may consist of five sets (the winner being the first to win three sets), while most matches are three sets (the winner being the first to win two sets). In tournament play, the chair umpire announces the end of the match with the well-known phrase "Game, set, match" followed by the winning team's name.

[edit] Rules variations
See also: Types of tennis match
No-ad: The first player or doubles team to four points wins the game. One side does not have to win by two points. When the game score reaches three points each, the receiver chooses which side of the court (advantage court or deuce court) the service is to be delivered on the seventh and game-deciding point.
Pro set: Instead of playing multiple sets, players may play one "pro set". A pro set is first to 8 (or 10) games by a margin of two games, instead of first to 6. A 12-point tiebreaker is usually played when the score is 8-8 (or 10-10). These are often played with no-ad scoring.
Match tie-break: This is sometimes played instead of a third set. This is played like a regular tie-break, but the winner must win ten points instead of seven. Match tie-breaks are used on the ATP and WTA tours for doubles and as a player's choice in USTA league play.
Another, however informal, tennis format is called "Kiwi doubles", "Canadian doubles" or "cut-throat"[1]. This involves three players, with one person playing a doubles team. The single player gets to utilize the alleys normally reserved only for a doubles team. Conversely, the doubles team does not use the alleys when executing a shot. The scoring is the same as a regular game. This format is not sanctioned by any official body and is only played when a fourth player is not available for normal doubles.
"Australian doubles," another informal and unsanctioned form of tennis, is played with similar rules to the "Kiwi" style, only in this version, players rotate court position after each game. As such, each player plays doubles and singles over the course of a match, with the singles player always serving. Scoring styles vary, but one popular method is to assign a value of 2 points to each game, with the server taking both points if he or she holds serve, and the doubles team each taking one if they break.
Wheelchair tennis can be played by able-bodied players as well as people who require a wheelchair for mobility. An extra bounce is permitted. This rule makes it possible to have mixed wheelchair and able-bodied matches. It is possible for a doubles team to consist of a wheelchair player and an able-bodied player (referred to as "one-up, one-down"), or for a wheelchair player to play against an able-bodied player. In such cases, the extra bounce is permitted for the wheelchair users only.

[edit] Surface
There are three main types of court surfaces, with one less common surface. Depending on the materials used, each surface provides a difference in the speed and bounce of the ball, which in turn can affect the level of play of individual players. The three most common surfaces are:
Clay – red clay (used at the French Open and many other tournaments, especially in Europe and Latin America), green clay (an example of which is Har-Tru and used mainly in the U.S.)
Hard – examples are acrylic (Plexicushion used at the Australian Open, DecoTurf used at the U.S. Open), asphalt, and concrete.
Grass – used at Wimbledon
Indoor courts are also used so play can continue year-round. Common indoor surfaces are hard, carpet, and clay. Some players are more successful on certain surfaces and are known as "specialists" for that particular court.
Clay courts are considered a "slow" surface because the loose surface causes the ball to lose speed rapidly and bounce higher. This makes it more difficult for a player to hit an unreturnable shot (a "winner") because the opponent has more time to reach and return the ball. Line calls are easily reviewable on this type of court because the ball generally leaves a visible mark. Courts are swept between sets, and at the end of every match, to erase any marks from the previous set or match.
Hardcourts are generally considered to be a "fast" surface. However, there are many different types of hardcourts, and depending on the court's construction, the speed of the court can also be relatively slow. The typical hardcourt is characterized by low bounces and high ball speed, giving fast-serving and hard-hitting players an advantage.
Grass is considered to be a very "fast" surface. For many years, three of the four Grand Slam tournaments were held on grass. This changed when the Australian Open and the U.S. Open changed to hardcourts. Grass courts cause the ball to bounce low, or even skid, which generally keeps rallies short. This gives hard-serving and hard-hitting players an advantage because their shots are amplified on this surface. Grass also can cause unpredictable ball bounces. The bounce of the ball on grass courts can be altered by the health of the grass, the type of grass used, and how recently it has been mown. For that reason and low, fast bounces, a player's net game becomes more vital. This is because volleying a ball before it bounds avoids the need to deal with unpredictable bounces.
Carpet is usually found only indoors though some synthetic grass types are used both indoors and outdoors. It is made from a surface layer of "carpet" placed on top of a hard surface such as asphalt. The surface layer is thin and resilient. Shots on carpet vary with the composition. The ball can bounce like shots on an average hard court or be even faster and slicker than grass.
Professional and recreational players often wear different types of shoes depending on the playing surface. Shoes must have soles that grip the ground securely so that players can start and stop quickly. Where the shoes differ is how they grip the surface. For example, clay court shoes need to provide grip and traction while allowing the player to slide. Hardcourt shoes should emphasize grip, traction, and ankle support.
