Cricket pitch


In the game of cricket, the cricket pitch consists of the central strip of the cricket fieldween the wickets - 1 chain or 22 yards (20.12 m) long and 10 feet (3 m) wide. The surface is very flat and normally covered with extremely short grass though this grass is soon removed by wear at the ends of the pitch.
In amateur matches, artificial pitches are commonly used. These can be a slab of concrete, overlaid with a coir mat, artificial turf, some times dirt is put over the coir mat to provide an authentic feeling pitch. Artificial pitches are rare in professional cricket—-being used only when exhibition matches are played in regions where cricket is not a common sport.
The pitch has very specific markings delineating the creases, as specified by the Laws of Cricket.
The word wicket often occurs in reference to the pitch. Although technically incorrect according the Laws of Cricket (Law 7 covers the pitch and Law 8 the wickets, distinguishing between them), cricket players, followers, and commentators persist in the usage, with context eliminating any possible ambiguity. Track is yet another synonym for pitch.
The rectangular central area of a pitch - the space used for pitches - is known as the square.
Protected area
A wicket consists of three stumps that are placed into the ground, and topped with two bails.
The protected area or danger area is the central portion of the pitch—a rectangle running down the middle of the pitch, two feet wide, and beginning five feet from each popping crease. Under the Laws of Cricket, a bowler must avoid running on this area during his follow-through after delivering the ball.
If a bowler runs on the protected area, an umpire will issue a warning to the bowler and to his team captain. The umpire issues a second and final warning if the bowler transgresses again. On the third offence, the umpire will eject the bowler from the attack and the bowler may not bowl again for the remainder of the innings.
The protected area is protected in this way because the ball normally bounces on the pitch within this region, and if it is scuffed or damaged by the bowler's footmarks it can give an unfair advantage to the bowling side. The rule does not prevent the bowler or any other fielder from running on the protected area in an effort to field the ball; it applies only to the uninterrupted follow-through.
State of the pitch

A perspective view of the cricket pitch from the bowler's end. The bowler runs in past one side of the wicket at the bowler's end, either 'over' the wicket or 'round' the wicket.
A natural pitch with grass longer or more moist than usual is described as a green pitch. This favours the bowler over the batsman as the ball can be made to behave erratically on longer or wet grass. Most club and social cricket is played on pitches that professional cricketers would call green.
A sticky wicket - a pitch that has become wet - causes the ball to behave erratically, particularly for the slower or spin bowlers. However, modern pitches are generally protected from rain and dew before and during games so a sticky pitch is rarely seen in first-class cricket. The phrase, however, has retained currency and extended beyond cricket to mean any difficult situation.
As a match progresses, the pitch dries out. The Laws of Cricket bar watering the pitch during a match. As it dries out, initially batting becomes easier as any moisture disappears. Over the course of a four or five day match, however, the pitch begins to crack, then crumble and become dusty. This kind of pitch is colloquially known as a 'dust bowl' or 'minefield'. This again favors bowlers, particularly spin bowlers who can obtain large amounts of traction on the surface and make the ball spin a long way.
This change in the relative difficulties of batting and bowling as the state of the pitch changes during a match is one of the primary strategic considerations that the captain of the team that wins the coin toss will take into account when deciding which team will bat first and can accordingly finalise his decisions.
[edit] Covering the pitch

The Cricket pitch dimensions
The pitch is said to be covered when the groundsmen have placed covers on it to protect it against rain or dew. The use or non-use of covers significantly affects the way the ball comes off the pitch, making the matter potentially controversial. Law 11 of the Laws of Cricket provides that during the match the pitch shall not be completely covered unless provided otherwise by regulations or by agreement before the toss. When possible, the bowlers' run ups are covered in inclement weather to keep them dry. If the pitch is covered overnight, the covers are removed in the morning at the earliest possible moment on each day that play is expected to take place. If covers are used during the day as protection from inclement weather or if inclement weather delays the removal of overnight covers, they are removed as soon as conditions allow. Excess water can be removed from a pitch or the outfield using a machine called a water hog.
