Cricket is a bat-and-ball game played on a cricket field (see image, right) between two teams of eleven players each. 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.
There are various formats ranging from Twenty20, played over a few hours with each team batting for a single innings of 20 overs, to Test matches, played over five days with unlimited overs and the teams each batting for two innings of unlimited length. Traditionally cricketers play in all-white kit, but in limited overs cricket they wear club or team colours. In addition to the basic kit, some players wear protective gear to prevent injury caused by the ball, which is a hard, solid spheroid made of compressed leather with a slightly raised sewn seam enclosing a cork core which is layered with tightly wound string.
The domestic competitions include the Ranji Trophy, the Duleep Trophy, the Vijay Hazare Trophy, the Deodhar Trophy, the Irani Trophy and the NKP Salve Challenger Trophy. In addition, the BCCI conducts the Indian Premier League, a Twenty20 competition, which is also one of the biggest sports leagues in the world and the biggest cricket league in the world. The Indian cricket team is also accredited with the honour of winning all the ICC tournaments under M.S. Dhoni's captaincy, which is a world record. While cricket is by far the most popular sport in the country it is not the country's national sport since India has no national sport.
Ganguly became the regular captain of the team in both Tests and ODIs in 2000. He remained captain until 2005–06 and became the then most successful Indian captain, winning 21 of his 49 Test matches in charge and 76 of his 146 ODIs. Under his captaincy, India became the joint-winners of the 2002 ICC Champions Trophy with Sri Lanka, and the runners-up of the 2003 Cricket World Cup. India lost only three Tests at home under Ganguly and managed to draw Test series in England and Australia. Rahul Dravid took over as Test captain in 2005. In 2006, he led India to its first Test series victory in the West Indies in more than 30 years.
