The ICC also organises competitions that are for several countries at once, including the Cricket World Cup, ICC T20 World Cup and ICC Champions Trophy. A league competition for Test matches played as part of normal tours, the ICC World Test Championship, had been proposed several times, and its first instance began in 2019. A league competition for ODIs, the 2020–22 ICC Cricket World Cup Super League, is planned to begin in 2020. The ICC maintains Test rankings, ODI rankings and T20 rankings systems for the countries which play these forms of cricket.
Before a match begins, the team captains (who are also players) toss a coin to decide which team will bat first and so take the first innings. Innings is the term used for each phase of play in the match. In each innings, one team bats, attempting to score runs, while the other team bowls and fields the ball, attempting to restrict the scoring and dismiss the batsmen. When the first innings ends, the teams change roles; there can be two to four innings depending upon the type of match. A match with four scheduled innings is played over three to five days; a match with two scheduled innings is usually completed in a single day. During an innings, all eleven members of the fielding team take the field, but usually only two members of the batting team are on the field at any given time. The exception to this is if a batsman has any type of illness or injury restricting his or her ability to run, in this case the batsman is allowed "A Runner" who can run between the wickets when the batsman hits a scoring run or runs. The order of batsmen is usually announced just before the match, but it can be varied.
A match's statistics are summarised on a scorecard. Prior to the popularisation of scorecards, most scoring was done by men sitting on vantage points cuttings notches on tally sticks and runs were originally called notches. According to Rowland Bowen, the earliest known scorecard templates were introduced in 1776 by T. Pratt of Sevenoaks and soon came into general use. It is believed that scorecards were printed and sold at Lord's for the first time in 1846.
At the grassroots level, local club cricket is essentially an amateur pastime for those involved but still usually involves teams playing in competitions at weekends or in the evening. Schools cricket, first known in southern England in the 17th century, has a similar scenario and both are widely played in the countries where cricket is popular. Although there can be variations in game format, compared with professional cricket, the Laws are always observed and club/school matches are therefore formal and competitive events. The sport has numerous informal variants such as French cricket.
As of 25 June 2019, India is ranked first in Tests, second in ODIs and fifth in T20Is by the ICC. Virat Kohli is the current captain of the team across all formats, while the head coach is Ravi Shastri. The Indian cricket team has rivalries with other Test-playing nations, most notably with Pakistan, the political arch-rival of India. However, in recent times, rivalries with nations like Australia, South Africa and England have also gained prominence.
Irani Trophy – The Trophy tournament was conceived during the 1959–60 season to mark the completion of 25 years of the Ranji Trophy championship and was named after the late Z.R. Irani, who was associated with the Board of Control for Cricket in India (BCCI) from its inception in 1928, till his death in 1970 and a keen patron of the game. The first match, played between the Ranji Trophy champions and the Rest of India was played in 1959–60. For the first few years, it was played at the tail end of the season. Realising the importance of the fixture, the BCCI moved it to the beginning of the season. Since 1965–66, it has traditionally heralded the start of the new domestic season. The Irani Trophy game ranks high in popularity and importance. It is one of the few domestic matches followed with keen interest by cricket lovers in the country. Leading players take part in the game, which has often been a sort of selection trial to pick the Indian team for foreign tours.
Single wicket was popular in the 18th and 19th centuries and its matches were generally considered top-class. In this form, although each team may have from one to six players, there is only one batsman in 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. Matches tended to have two innings per team like a full first-class one and they could end in a draw.
