The ball is a hard leather-seamed spheroid, with a circumference of 22.9 centimetres (9.0 in). The ball has a "seam": six rows of stitches attaching the leather shell of the ball to the string and cork interior. The seam on a new ball is prominent and helps the bowler propel it in a less predictable manner. During matches, the quality of the ball deteriorates to a point where it is no longer usable; during the course of this deterioration, its behaviour in flight will change and can influence the outcome of the match. Players will, therefore, attempt to modify the ball's behaviour by modifying its physical properties. Polishing the ball and wetting it with sweat or saliva is legal, even when the polishing is deliberately done on one side only to increase the ball's swing through the air, but the acts of rubbing other substances into the ball, scratching the surface or picking at the seam are illegal ball tampering.[71]
First-class cricket in England is played for the most part by the 18 county clubs which contest the County Championship. The concept of a champion county has existed since the 18th century but the official competition was not established until 1890.[40] The most successful club has been Yorkshire, who had won 32 official titles (plus one shared) as of 2019.[123]
During normal play, thirteen players and two umpires are on the field. Two of the players are batsmen and the rest are all eleven members of the fielding team. The other nine players in the batting team are off the field in the pavilion. The image with overlay below shows what is happening when a ball is being bowled and which of the personnel are on or close to the pitch.[72]

Cricket has close historical ties with Australian rules football and many players have competed at top levels in both sports.[136] In 1858, prominent Australian cricketer Tom Wills called for the formation of a "foot-ball club" with "a code of laws" to keep cricketers fit during the off-season. The Melbourne Football Club was founded the following year, and Wills and three other members codified the first laws of the game.[137] It is typically played on modified cricket fields.[138]
If a fielder is injured or becomes ill during a match, a substitute is allowed to field instead of him, but the substitute cannot bowl or act as a captain. The substitute leaves the field when the injured player is fit to return.[74] The Laws of Cricket were updated in 2017 to allow substitutes to act as wicket-keepers,[75] a situation that first occurred when Mumbai Indians' wicket-keeper Ishan Kishan was injured in a match on 18 April 2018.[76]
In 2014, Virat Kohli became the first cricketer to win back-to-back man of the series awards in the 2012 ICC World Twenty20 and 2014 ICC World Twenty20. In 2017, Ravichandran Ashwin became the fastest cricketer in history to reach 250 wickets. He and Ravindra Jadeja are considered to be the best bowlers in Test cricket and occupy the top two spots in the rankings for Test bowlers as of May 2017. Virat Kohli became the first captain in history to score double tons in three consecutive series, against New Zealand, England and Bangladesh in 2017.

The most famous player of the 19th century was W. G. Grace, who started his long and influential career in 1865. It was especially during the career of Grace that the distinction between amateurs and professionals became blurred by the existence of players like him who were nominally amateur but, in terms of their financial gain, de facto professional. Grace himself was said to have been paid more money for playing cricket than any professional.[citation needed]
2015 saw the beginning of India's dominance at home in Test matches under new captain Virat Kohli when they comprehensively beat South Africa. This series was the beginning of an unbeaten streak of 19 Test matches for India which was brought to an end by Australia in early 2017. This series also saw the emergence of Ravichandran Ashwin and Ravindra Jadeja as two of the best spinners and all-rounders. They spun webs around touring batsmen, much like the spinning quartet of the 1970s. This was followed by limited overs victories over Australia and Sri Lanka away from home. India was knocked out of the 2015 World Cup in the semi-final stage, to eventual winners Australia. India began 2016 by winning the 2016 Asia Cup, remaining unbeaten throughout the tournament, beating Pakistan along the way. India were favourites to win the 2016 ICC World Twenty20 which was being held at home, but they lost in the semi-final to eventual champions West Indies. Virat Kohli was again named the man of the series.
India was invited to The Imperial Cricket Council in 1926, and made their debut as a Test playing nation in England in 1932, led by CK Nayudu, who was considered as the best Indian batsman at the time.[16] The one-off Test match between the two sides was played at Lord's in London. The team was not strong in their batting at this point and went on to lose by 158 runs.[17] India hosted its first Test series in the year 1933. England was the visiting team that played 2 Tests in Bombay (now Mumbai) and Calcutta (now Kolkata). The visitors won the series 2-0. The Indian team continued to improve throughout the 1930s and '40s but did not achieve an international victory during this period. In the early 1940s, India didn't play any Test cricket due to the Second World War. The team's first series as an independent country was in late 1947 against Sir Donald Bradman's Invincibles (a name given to the Australia national cricket team of that time). It was also the first Test series India played which was not against England. Australia won the five-match series 4–0, with Bradman tormenting the Indian bowling in his final Australian summer.[18] India subsequently played their first Test series at home not against England against the West Indies in 1948. West Indies won the 5-Test series 1–0.[19]

Cricket is a bat-and-ball game played on a cricket field (see image, right) between two teams of eleven players each.[58] The field is usually circular or oval in shape and the edge of the playing area is marked by a boundary, which may be a fence, part of the stands, a rope, a painted line or a combination of these; the boundary must if possible be marked along its entire length.[59]
