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.
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.
Eden Gardens in Kolkata has hosted the most Tests, and also has the second-largest seating capacity of any cricket stadium in the world, being capable of holding more than 66,000 spectators. Founded in 1864, it is one of the most historical stadiums in India, having hosted numerous historical and controversial matches. Other major stadiums in India include the Feroz Shah Kotla Ground, which was established in 1883 and hosted memorable matches including Anil Kumble's ten wickets in an innings haul against Pakistan. For the last two years, the ground has been undergoing renovation.
