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.
Often, fans engage in protests regarding players if they believe that regionalism has affected selection, or because of regional partisan support for local players. In 2005, when Sourav Ganguly was dropped from the team, Ganguly's home town Kolkata erupted in protests. India later played a match against South Africa in Kolkata, West Bengal. The Indian team was booed by the crowd who supported South Africa instead of India in response to Ganguly's dropping. Similar regional divisions in India regarding selection have also caused protests against the team, with political activists from the regional Kalinga Kamgar Sena party in Odisha disrupting the arrival of the team in Cuttack for an ODI over the lack of a local player in the team, with one activist manhandling coach Greg Chappell. Similar treatment was handed to Sunil Gavaskar in the 1987 World Cup Semi Finals by crowds at Wankhede Stadium when he got bowled by Philip DeFreitas.
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.
