The key to India's bowling in the 1970s were the Indian spin quartet – Bishen Bedi, E.A.S. Prasanna, BS Chandrasekhar and Srinivas Venkataraghavan. This period also saw the emergence of two of India's best ever batsmen, Sunil Gavaskar and Gundappa Viswanath. Indian pitches have had the tendency to support spin and the spin quartet exploited this to create collapses in opposing batting line-ups. These players were responsible for the back-to-back series wins in 1971 in the West Indies and in England, under the captaincy of Ajit Wadekar. Gavaskar scored 774 runs in the West Indian series while Dilip Sardesai's 112 played a big part in their one Test win.
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.
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.
In the approximate centre of the field is a rectangular pitch (see image, below) on which a wooden target called a wicket is sited at each end; the wickets are placed 22 yards (20 m) apart. The pitch is a flat surface 3 metres (9.8 ft) wide, with very short grass that tends to be worn away as the game progresses (cricket can also be played on artificial surfaces, notably matting). Each wicket is made of three wooden stumps topped by two bails.
