Duleep Trophy – Named after Duleepsinhji, the Duleep Trophy competition, which is a first-class competition started by the Board of Control for Cricket in India in 1961–62 with the aim of providing a greater competitive edge in domestic cricket. Because apart from the knock-out stages of the Ranji Trophy, that competition proven to be highly predictable, with Bombay winning for the Ranji trophy for fifteen consecutive years. The Duleep Trophy was also meant to help the selectors to assessing form of top cricketers playing against each other. The original format had five teams, which were drawn from the five zones (i.e. North, South, East, West and central), play each other on a knock-out basis. From the 1993–94 season, the competition has been converted to a league format.
Different designs were adopted on the playing jerseys over the years and the most predominant one has been 'India' text written in yellow over a diagonal splash of the tricolour. Nike acquired the kit manufacturing rights for the team in 2005 and designed new jerseys for the 2007 World Cup with the lightest shade of blue used by the team till date and golden yellow as the secondary colour. A new tricolour accent was implemented on the right side of the jersey. The colour was changed to a darker feroza blue in 2009 with orange replacing yellow as the secondary colour.
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.
Cricket has close historical ties with Australian rules football and many players have competed at top levels in both sports. 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. It is typically played on modified cricket fields.
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.
During the 1980s, India developed a more attack-focused batting line-up with talented batsmen such as Mohammad Azharuddin, Dilip Vengsarkar and Ravi Shastri prominent during this decade. (Despite India's victory in the Cricket World Cup in 1983, the team performed poorly in the Test arena, including 28 consecutive Test matches without a victory. However, India won the Asia Cup in 1984 and won the World Championship of Cricket in Australia in 1985.) The 1987 Cricket World Cup was held in India.
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.
