Captain (cricket)

The toss

Starting from team selection and then toss Before the start of a match the home captain tosses a coin and the away captain calls heads or tails. The captain who wins the toss is given the choice of whether to bat or bowl first.^[4] The decision usually depends on the condition of the pitch and whether it is likely to deteriorate, the weather conditions and the weather forecast.

The decision also depends on the relative strengths of the team's batting and bowling. For instance in Test cricket, a side with only fast bowlers may choose to bowl first to try to take advantage of any early moisture in the pitch, knowing that it will be harder to take wickets later in the match. Similarly a side with a weak opening batting pair may choose to bowl first in order to protect their batsmen.^[5]

Fielding positions

The captain decides where the fielders will stand, in consultation with the bowler and sometimes other senior players. The fielding positions will usually be dictated by the type of bowler, the batsman's batting style, and the captain's assessment of the state of the match (and hence whether to set an attacking or a defensive field).^[4]

Bowling

The captain decides when each bowler will bowl. If a batsman is seeking to dominate the current bowler, the captain may ask someone else to bowl; alternatively, keeping the bowler on may be deemed the best chance of getting the batsman out or restricting the scoring rate. If the regular bowlers are not achieving the desired results, the captain may decide to use non-regular bowlers to attempt to unsettle the batsmen. The captain may also change the bowlers around to introduce variation, and to prevent the batsmen getting "set".^[4]

In limited overs cricket the captain additionally has to make certain that bowlers bowl no more than their allotted maximum number of overs, and that experienced bowlers are available at the end of the batting side's innings, when the batsmen are usually looking to take risks to attack and score quickly.^[4]

In the longer forms of cricket, when a new ball becomes available the captain decides whether to use it, and when given that it can be taken any time after it becomes available.^[4]

Batting order

When the team bats, the captain decides the batting order. In professional cricket the captain usually changes the established batting order only for exceptional reasons, because batsmen tend to specialise in batting at certain positions. However, in certain circumstances it may be in the team's interest to change the batting order. If quick runs are needed, a naturally attacking batsman may be promoted up the order. A player who is 'in form' may be promoted to a higher batting position, at the expense of a player who is 'out of form'.^[4]

If a wicket falls near the end of a day's play, especially if the light is failing, or if the bowlers seem particularly confident, the captain may choose to send in a non-specialist batsman, referred to as a nightwatchman. If the nightwatchman does not get out before the end of that day's play then the specialist batsman will have been protected, and will not need to bat until the following day when conditions are likely to have improved. If the nightwatchman does get out, the cost of losing a late wicket will have been minimised, because the specialist batsman is still available to bat.^[4]

Declarations

The captain may declare the team's innings closed at any time, but usually only does so as an attacking ploy, for instance if the captain thinks the team has enough runs to win the match, or if a sudden change in conditions has made it advantageous to bowl rather than bat.^[4]

Follow-on

In a two-innings match, if the situation arises the captain decides whether to impose the follow-on.^[4]

Appeals

Fielding captains may withdraw appeals with consent of the umpires.^[6] This often occurs in cases of injury, miscommunication, or unsportsmanlike conduct, and is considered to uphold the spirit of cricket and fair play within the game.

Miscellaneous

The captain is also consulted on whether an injured batsman from the opposing team may use a runner when batting. Permission is usually given if the batsman has become injured during the course of the match, but if the batsman was carrying the injury at the start of the match then the captain may refuse. (As of 2012, runners are not allowed in Test cricket and injured batsmen are required to continue batting with the injury or retire hurt.)^[7]
