Controversies followed the event as at times Hawk-Eye produced erroneous output. In , tennis players were allowed three incorrect challenges per set instead.

Any leftover challenges did not carry over to the next set. As a result, the point was replayed and Mauresmo did not lose an incorrect challenge.

Defending champion Rafael Nadal accused the system of incorrectly declaring an out ball to be in following his exit.

The umpire had called a ball out; when Mikhail Youzhny challenged the decision, Hawk-Eye said it was in by 3 mm.

Nadal could only shrug, saying that had this system been on clay, the mark would have clearly shown Hawk-Eye to be wrong.

The Wimbledon Championships also implemented the Hawk-Eye system as an officiating aid on Centre Court and Court 1, and each tennis player was allowed three incorrect challenges per set.

If the set produced a tiebreaker, each player was given an additional challenge. Additionally, during the finals of Federer against Rafael Nadal , Nadal challenged a shot which was called out.

Hawk-Eye showed the ball as in, just clipping the line. The reversal agitated Federer enough for him to request unsuccessfully that the umpire turn off the Hawk-Eye technology for the remainder of the match.

The Hawk-Eye system was not available when he challenged, likely due to a particularly pronounced shadow on the court.

As a result, the original call stood. The Hawk-Eye system indicated that the ball landed on the center of the line despite instant replay images showing that the ball was clearly out.

It was later revealed that the Hawk-Eye system had mistakenly picked up the second bounce, which was on the line, instead of the first bounce of the ball.

The Hawk-Eye system was developed as a replay system, originally for TV broadcast coverage. As such, it initially could not call ins and outs live.

The Hawk-Eye Innovations website [18] states that the system performs with an average error of 3. This is roughly equivalent to the fluff on the ball.

The technology is currently in trials and is expected to be in place for the US Open. Currently, only clay court tournaments, notably the French Open being the only Grand Slam, are found to be generally free of Hawk-Eye technology due to marks left on the clay where the ball bounced to evidence a disputed line call.

A key example of this was the number of challenges a player was permitted per set, which varied among events. In an advantage set a set with no tiebreak players are allowed three unsuccessful challenges every 12 games.

Hawk-Eye tracks the ball, and informs the referee if a ball fully crosses the goal line into the goal. The purpose of the system is to eliminate errors in assessing if a goal was scored.

GLT is not compulsory and, owing to the cost of Hawk-Eye and its competitors, systems are only deployed in a few high-level competitions. As of July [update] , licensed Hawk-Eye systems are installed at 96 stadiums.

At the World Snooker Championship , the BBC used Hawk-Eye for the first time in its television coverage to show player views, particularly of potential snookers.

The BBC used to use the system sporadically, for instance in the Masters at Wembley the Hawk-Eye was at most used once or twice per frame. A trial took place in Croke Park on 2 April The double-header featured football between Dublin and Down and hurling between Dublin and Kilkenny.

Over the previous two seasons there had been many calls for the technology to be adopted, especially from Kildare fans, who saw two high-profile decisions go against their team in important games.

Use of Hawk-Eye was suspended during the All-Ireland hurling semi-finals on 18 August due to a human error during an Under hurling game between Limerick and Galway.

There have been no further incidents during the GAA. Hawk-Eye was introduced to a second venue, Semple Stadium , Thurles, in There is no TV screen at Semple: Hawk-Eye is now familiar to sport fans around the world for the views it brings into sports like cricket and tennis.

Although this new technology has for the most part been embraced, it has been criticised by from some quarters. In , an article in a peer-reviewed journal [43] consolidated many of these doubts.

The authors acknowledged the value of the system, but noted that it was probably fallible to some extent, and that its failure to depict a margin of error gave a spurious depiction of events.

The authors also argued that the probable limits to its accuracy were not acknowledged by players, officials, commentators or spectators.

They hypothesised that Hawk-Eye may struggle with predicting the trajectory of a cricket ball after bouncing: 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. 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 serve.

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. In most professional play and some amateur competition, there is an officiating head judge or chair umpire usually referred to as the umpire , who sits in a raised chair to one side of the court.

The umpire has absolute authority to make factual determinations. The umpire may be assisted by line judges, who determine whether the ball has landed within the required part of the court and who also call foot faults.

There also may be a net judge who determines whether the ball has touched the net during service. The umpire has the right to overrule a line judge or a net judge if the umpire is sure that a clear mistake has been made.

In some tournaments, line judges who would be calling the serve, were assisted by electronic sensors that beeped to indicate the serve was out.

This system was called " Cyclops ". The referee, who is usually located off the court, is the final authority about tennis rules. Ball boys and girls may be employed to retrieve balls, pass them to the players, and hand players their towels.

They have no adjudicative role. In rare events e. The umpire may consider their statements when making a decision. In some leagues, especially junior leagues, players make their own calls, trusting each other to be honest.

This is the case for many school and university level matches. In unofficiated matches, a ball is out only if the player entitled to make the call is sure that the ball is out.

In tennis, a junior is a player under 18 who is still legally protected by a parent or guardian. Players on the main adult tour who are under 18 must have documents signed by a parent or guardian.

These players, however, are still eligible to play in junior tournaments. Most juniors who enter the international circuit do so by progressing through ITF, Satellite, Future, and Challenger tournaments before entering the main circuit.

The latter three circuits also have adults competing in them. In , the ITF implemented a new rankings scheme to encourage greater participation in doubles, by combining two rankings singles and doubles into one combined tally.

Juniors may earn income from tennis by participating in the Future, Satellite, or Challenger tours. Tournaments are broken up into different tiers offering different amounts of ranking points, culminating with Grade A.

Leading juniors are allowed to participate for their nation in the Junior Fed Cup and Davis Cup competitions. To succeed in tennis often means having to begin playing at a young age.

Juniors develop their play through a range of tournaments on all surfaces, accommodating all different standards of play. Talented juniors may also receive sponsorships from governing bodies or private institutions.

A tennis match is intended to be continuous. In most cases, service is required to occur no more than 20 seconds after the end of the previous point.

Should a player be determined to be stalling repeatedly, the chair umpire may initially give a warning followed by subsequent penalties of "point", "game", and default of the match for the player who is consistently taking longer than the allowed time limit.

In the event of a rain delay, darkness or other external conditions halting play, the match is resumed at a later time, with the same score as at the time of the delay, and the players at the same end of the court when rain halted play, or at the same position north or south if play is resumed on a different court.

Balls wear out quickly in serious play and, therefore, in ATP and WTA tournaments, they are changed after every nine games with the first change occurring after only seven games, because the first set of balls is also used for the pre-match warm-up.

A recent rule change is to allow coaching on court on a limited basis during a match. A competent tennis player has eight basic shots in his or her repertoire: A grip is a way of holding the racket in order to hit shots during a match.

The grip affects the angle of the racket face when it hits the ball and influences the pace, spin, and placement of the shot. Players use various grips during play, including the Continental The "Handshake Grip" , Eastern Can be either semi-eastern or full eastern.

Usually used for backhands. Most players change grips during a match depending on what shot they are hitting; for example, slice shots and serves call for a Continental grip.

A serve or, more formally, a "service" in tennis is a shot to start a point. The serve is initiated by tossing the ball into the air and hitting it usually near the apex of its trajectory into the diagonally opposite service box without touching the net.

The serve may be hit under- or overhand although underhand serving remains a rarity. Experienced players strive to master the conventional overhand serve to maximize its power and placement.

The server may employ different types of serve including flat serve, topspin serve, slice serve, and kick American twist serve.

A reverse type of spin serve is hit in a manner that spins the ball opposite the natural spin of the server, the spin direction depending upon right- or left-handedness.

Some servers are content to use the serve simply to initiate the point; however, advanced players often try to hit a winning shot with their serve.

A winning serve that is not touched by the opponent is called an "ace". For a right-handed player, the forehand is a stroke that begins on the right side of the body, continues across the body as contact is made with the ball, and ends on the left side of the body.

There are various grips for executing the forehand, and their popularity has fluctuated over the years. The most important ones are the continental , the eastern , the semi-western , and the western.

For a number of years, the small, frail s player Bill Johnston was considered by many to have had the best forehand of all time, a stroke that he hit shoulder-high using a western grip.

Few top players used the western grip after the s, but in the latter part of the 20th century, as shot-making techniques and equipment changed radically, the western forehand made a strong comeback and is now used by many modern players.

No matter which grip is used, most forehands are generally executed with one hand holding the racket, but there have been fine players with two-handed forehands.

For right-handed players, the backhand is a stroke that begins on the left side of their body, continues across their body as contact is made with the ball, and ends on the right side of their body.

It can be executed with either one hand or with both and is generally considered more difficult to master than the forehand.

For most of the 20th century, the backhand was performed with one hand, using either an eastern or a continental grip. The first notable players to use two hands were the s Australians Vivian McGrath and John Bromwich , but they were lonely exceptions.

Two hands give the player more control, while one hand can generate a slice shot, applying backspin on the ball to produce a low trajectory bounce.

Reach is also limited with the two-handed shot. The player long considered to have had the best backhand of all time, Don Budge , had a powerful one-handed stroke in the s and s that imparted topspin onto the ball.

Ken Rosewall , another player noted for his one-handed backhand, used a very accurate slice backhand through the s and s. A small number of players, notably Monica Seles , use two hands on both the backhand and forehand sides.

The half volley is made by hitting the ball on the rise just after it has bounced, also generally in the vicinity of the net, and played with the racket close to the ground.

If the lob is not hit deeply enough into the other court, however, an opponent near the net may then hit an overhead smash , a hard, serve-like shot, to try to end the point.

A difficult shot in tennis is the return of an attempted lob over the backhand side of a player. When the contact point is higher than the reach of a two-handed backhand, most players will try to execute a high slice under the ball or sideways.

Fewer players attempt the backhand sky-hook or smash. Rarely, a player will go for a high topspin backhand, while themselves in the air.

A successful execution of any of these alternatives requires balance and timing, with less margin of error than the lower contact point backhands, since this shot is a break in the regular pattern of play.

If an opponent is deep in his court, a player may suddenly employ an unexpected drop shot , by softly tapping the ball just over the net so that the opponent is unable to run in fast enough to retrieve it.

Advanced players will often apply back spin to a drop shot, causing the ball to "skid" upon landing and bounce sideways, with less forward momentum toward their opponent, or even backwards towards the net, thus making it even more difficult to return.

Muscle strain is one of the most common injuries in tennis. Muscle , cartilage , nerves , bursae , ligaments and tendons may be damaged from overuse.

The repetitive use of a particular muscle without time for repair and recovery is the most common cause of injury.

Tournaments are often organized by gender and number of players. Tournaments may be organized for specific age groups, with upper age limits for youth and lower age limits for senior players.

There are also tournaments for players with disabilities, such as wheelchair tennis and deaf tennis. Most large tournaments seed players, but players may also be matched by their skill level.

According to how well a person does in sanctioned play, a player is given a rating that is adjusted periodically to maintain competitive matches.

Average club players under this system would rate 3. The four Grand Slam tournaments are considered to be the most prestigious tennis events in the world.

Aside from the historical significance of these events, they also carry larger prize funds than any other tour event and are worth double the number of ranking points to the champion than in the next echelon of tournaments, the Masters men and Premier events women.

There are , more than any other professional tennis tournament. Grand Slam tournaments are among the small number of events that last two weeks, the others being the Indian Wells Masters and the Miami Masters.

Currently, the Grand Slam tournaments are the only tour events that have mixed doubles contests. Grand Slam tournaments are held in conjunction with wheelchair tennis tournaments and junior tennis competitions.

These tournaments also contain their own idiosyncrasies. For example, players at Wimbledon are required to wear predominantly white.

Each event is held annually, and a win at one of these events is worth ranking points. It is currently held in London, England.

In August the ATP announced major changes to the tour that were introduced in The Masters Series was renamed to the "Masters ", the addition of the number referring to the number of ranking points earned by the winner of each tournament.

Contrary to earlier plans, the number of tournaments was not reduced from nine to eight and the Monte Carlo Masters remains part of the series although, unlike the other events, it does not have a mandatory player commitment.

The Hamburg Masters has been downgraded to a point event. It is mandatory for leading players to enter at least four events, including at least one after the US Open.

It is composed of about events and, as a result, features a more diverse range of countries hosting events. These events offer the largest rewards in terms of points and prize money.

The Premier events were introduced in replacing the previous Tier I and II tournament categories. Currently four tournaments are Premier Mandatory, five tournaments are Premier 5, and twelve tournaments are Premier.

International tournaments are the second main tier of the WTA tour and consist of 31 tournaments, with a prize money for every event at U.

Professional tennis players enjoy the same relative perks as most top sports personalities: Like players of other individual sports such as golf, they are not salaried, but must play and finish highly in tournaments to obtain money.

The following players have won at least five singles titles at Grand Slam tournaments:. A frequent topic of discussion among tennis fans and commentators is who was the greatest male singles player of all time.

By a large margin, an Associated Press poll in named Bill Tilden as the greatest player of the first half of the 20th century. In , however, Donald Budge became the first person to win all four major singles titles during the same calendar year, the Grand Slam , and won six consecutive major titles in and Tilden called Budge "the finest player days a year that ever lived.

Kramer was among the few who dominated amateur and professional tennis during the late s and early s.

Tony Trabert has said that of the players he saw before the start of the open era , Kramer was the best male champion.
