Dismissals (outs)

Wicketkeeper Mahendra Singh Dhoni of India successfully stumps a South African batsman out during a match played in Chennai in 2008.
There are ten ways in which a batsman can be dismissed and some are so unusual that only a few instances of them exist in the whole history of the game. The common forms of dismissal are "bowled", "caught", "leg before wicket" (lbw), "run out", and "stumped". The unusual methods are "hit wicket", "hit the ball twice", "obstructed the field", "handled the ball" and "timed out".
Before the umpire will award a dismissal and declare the batsman to be out, a member of the fielding side (generally the bowler) must "appeal". This is invariably done by asking (or shouting) the term "Howzat?" which means, simply enough, "How is that?" If the umpire agrees with the appeal, he will raise a forefinger and say "Out!". Otherwise he will shake his head and say "Not out". Appeals are particularly loud when the circumstances of the claimed dismissal are unclear, as is always the case with lbw and often with run outs and stumpings.
  1. Bowled: the bowler has hit the wicket with the ball and the wicket has "broken" with at least one bail being dislodged (note that if the ball hits the wicket without dislodging a bail it is not out).[30]
  2. Caught: the batsman has hit the ball with his bat, or with his hand which was holding the bat, and the ball has been caught before it has touched the ground by a member of the fielding side.[31]
  3. Leg before wicket (lbw): first and foremost, the ball must, in the opinion of the on-field umpire, be going on to hit the stumps if the ball had not hit the pad of the batsman first. If the batsman plays an attempted shot to the delivery, then the ball must hit the batsman's pad in line with the stumps and be going on to hit the stumps for the batsman to be given out. If the batsman does not attempt to play a shot, then the ball does not have to hit the pad in line with the stumps but it still must be going on to hit the stumps. If the ball pitches outside the leg stump, then the batsman cannot be given out under any circumstances.[32]
  4. Run out: a member of the fielding side has broken or "put down" the wicket with the ball while a batsman was out of his ground; this usually occurs by means of an accurate throw to the wicket while the batsmen are attempting a run.[33]
  5. Stumped is similar except that it is done by the wicketkeeper after the batsman has missed the bowled ball and has stepped out of his ground, and is not attempting a run.[34]
  6. Hit wicket: a batsman is out hit wicket, if he dislodges one or both bails with his bat, person, clothing or equipment in the act of receiving a ball, or in setting off for a run having just received a ball.[35]
  7. Hit the ball twice is very unusual and was introduced as a safety measure to counter dangerous play and protect the fielders. The batsman may legally play the ball a second time only to stop the ball hitting the wicket after he has already played it.[36]
  8. Obstructed the field: another unusual dismissal which tends to involve a batsman deliberately getting in the way of a fielder.[37]
  9. Handled the ball: a batsman must not deliberately touch the ball with his hand, for example to protect his wicket (note that the bowled ball often hits the batsman's hand while it is holding the bat but this is not out; though he can of course be caught off his hand).[38]
  10. Timed out usually means that the next batsman did not arrive at the wicket within three minutes of the previous one being dismissed.[39]
In the vast majority of cases, it is the striker who is out when a dismissal occurs. If the non-striker is dismissed it is usually by being run out, but he could also be dismissed for obstructing the field, handling the ball or being timed out.
A batsman may leave the field without being dismissed. If injured or taken ill the batsman may temporarily retire, and be replaced by the next batsman. This is recorded as retired hurt or retired ill. The retiring batsman is not out, and may resume the innings later. An unimpaired batsman may retire, and this is treated as being dismissed retired out; no player is credited with the dismissal. Batsmen cannot be out bowled, caught, leg before wicket, stumped or hit wicket off a no ball. They cannot be out bowled, caught, leg before wicket, or hit the ball twice off a wide. Some of these modes of dismissal can occur without the bowler bowling a delivery. The batsman who is not on strike may be run out by the bowler if he leaves his crease before the bowler bowls, and a batsman can be out obstructing the field or retired out at any time. Timed out is, by its nature, a dismissal without a delivery. With all other modes of dismissal, only one batsman can be dismissed per ball bowled.

Innings closed

An innings is closed when:
  1. Ten of the eleven batsmen are out (have been dismissed); in this case, the team is said to be "all out"
  2. The team has only one batsman left who can bat, one or more of the remaining players being unavailable owing to injury, illness or absence; again, the team is said to be "all out"
  3. The team batting last reaches the score required to win the match
  4. The predetermined number of overs has been bowled (in a one-day match only, commonly 50 overs; or 20 in Twenty20)
  5. A captain declares his team's innings closed while at least two of his batsmen are not out (this does not apply in one-day limited over matches)

Results

If the team that bats last is all out having scored fewer runs than their opponents, the team is said to have "lost by n runs" (where n is the difference between the number of runs scored by the teams). If the team that bats last scores enough runs to win, it is said to have "won by n wickets", where n is the number of wickets left to fall. For instance a team that passes its opponents' score having only lost six wickets would have won "by four wickets".
In a two-innings-a-side match, one team's combined first and second innings total may be less than the other side's first innings total. The team with the greater score is then said to have won by an innings and n runs, and does not need to bat again: n is the difference between the two teams' aggregate scores.
If the team batting last is all out, and both sides have scored the same number of runs, then the match is a tie; this result is quite rare in matches of two innings a side. In the traditional form of the game, if the time allotted for the match expires before either side can win, then the game is declared a draw.
If the match has only a single innings per side, then a maximum number of deliveries for each innings is often imposed. Such a match is called a "limited overs" or "one-day" match, and the side scoring more runs wins regardless of the number of wickets lost, so that a draw cannot occur. If this kind of match is temporarily interrupted by bad weather, then a complex mathematical formula, known as the Duckworth-Lewis method after its developers, is often used to recalculate a new target score. A one-day match can also be declared a "no-result" if fewer than a previously agreed number of overs have been bowled by either team, in circumstances that make normal resumption of play impossible; for example, wet weather.

Distinctive elements

Individual focus

For a team sport, cricket places individual players under unusual scrutiny and pressure. Bowler, Batsman, and fielder all act essentially independent of each other. While team managements can signal bowler or batsman to pursue certain tactics, the execution of the play itself is a series of solitary acts. Cricket is more similar to baseball than many other team sports in this regard: while the individual focus in cricket is slightly mitigated by the importance of the batting partnership and the practicalities of running, it is enhanced by the fact that a batsman may occupy the wicket for a long time.

Spirit of the Game

Cricket is a unique game where in addition to the laws, the players have to abide by Spirit of the Game.[40] The standard of sportsmanship has historically been considered so high that the phrase "it's just not cricket" was coined in the 19th Century to describe unfair or underhanded behaviour in any walk of life. In the last few decades though, cricket has become increasingly fast-paced and competitive, increasing the use of appealing and sledging, although players are still expected to abide by the umpires' rulings without argument, and for the most part they do. Even in the modern game fielders are known to signal to the umpire that a boundary was hit, despite what could have been considered a spectacular save (though they might be found out by the TV replays anyway). In addition to this, some cricket batsmen, like Sachin Tendulkar and Adam Gilchrist have been known to "walk" when they think they are out even if the umpire does not declare them out. This is a high level of sportsmanship, as a batsman can easily take advantage of incorrect umpiring decisions.

Influence of weather

Cricket is a sport played predominantly in the drier periods of the year. But, even so, the weather is a major factor in all cricket matches.
A scheduled game of cricket cannot be played in wet weather. Dampness affects the bounce of the ball on the wicket and is a risk to all players involved in the game. Many grounds have facilities to cover the cricket pitch (or the wicket). Covers can be in the form of sheets being laid over the wicket to elevated covers on wheels (using the same concept as an umbrella) to even hover covers which form an airtight seal around the wicket. However, most grounds do not have the facilities to cover the outfield. This means that in the event of heavy bouts of bad weather, games may be cancelled, abandoned or suspended due to an unsafe outfield.
Another factor in cricket is the amount of light available. At grounds without floodlights (or in game formats which disallow the use of floodlights), umpires can stop play in the event of bad light as it becomes too difficult for the batsmen to be able to see the ball coming at them, (and in extreme cases, members of the fielding team).
On the other hand, in instances of good light, batsmen can utilize sight-screens which enable batsmen to have a white background against which they can pick out the red ball (or black background for white ball) with greater ease.
The umpires always have the final decision on weather related issues.

Uniqueness of each field

Unlike those of most sports, cricket playing fields can vary significantly in size and shape. While the dimensions of the pitch and infield are specifically regulated, the Laws of Cricket do not specify the size or shape of the field.[22] Pitch and outfield variations can have a significant effect on how balls behave and are fielded as well as on batting. Pitches vary in consistency, and thus in the amount of bounce, spin, and seam movement available to the bowler. Hard pitches are usually good to bat on because of high but even bounce. Dry pitches tend to deteriorate for batting as cracks often appear, and when this happens to the pitch, spinners can play a major role. Damp pitches, or pitches covered in grass (termed "green" pitches), allow good fast bowlers to extract extra bounce. Such pitches tend to offer help to fast bowlers throughout the match, but become better for batting as the game goes on. While players of other outdoor sports deal with similar variations of field surface and stadium covering, the size and shape of their fields are much more standardized. Other local factors, such as altitude and climate, can also significantly affect play. These physical variations create a distinctive set of playing conditions at each ground. A given ground may acquire a reputation as batsman friendly or bowler friendly if one or the other discipline notably benefits from its unique mix of elements. The absence of a standardized field affects not only how particular games play out, but the nature of team makeup and players' statistical records.

Types of matches

Cricket is a multi-faceted sport which, in very broad terms, can be divided into major cricket and minor cricket based on playing standards. A more pertinent division, particularly in terms of major cricket, is between matches in which the teams have two innings apiece and those in which they have a single innings each. The former, known as first-class cricket, has a duration of three to five days (there have been examples of "timeless" matches too); the latter, known as limited overs cricket because each team bowls a limit of typically 50 or 20 overs, has a planned duration of one day only (a match can be extended if necessary due to bad weather, etc.).
Typically, two-innings matches have at least six hours of playing time each day. Limited overs matches often last six hours or more. There are usually formal intervals on each day for lunch and tea with brief informal breaks for drinks. There is also a short interval between innings. Historically, a form of cricket known as single wicket had been extremely successful and many of these contests in the 18th and 19th centuries qualify as major cricket matches. In this form, although each team may have from one to six players, there is only one batsman at a time and he must face every delivery bowled while his innings lasts. Single wicket has rarely been played since limited overs cricket began.
