Gundappa Ranganath Viswanath pronunciation (born 12 February 1949) is a former Indian cricketer.
He was one of India's finest batsmen throughout the 1970s.
Viswanath played Test cricket for India from 1969 to 1983 making 91 appearances and scoring over 6000 runs.
He also played in One Day Internationals from 1974 to 1982 including the World Cups of 1975 and 1979.
At state level, he played for Karnataka (formerly Mysore) throughout his career.
Viswanath, popularly nicknamed "Vishy", had an elegant and wristy batting style which emphasised timing rather than power.
Though he had a complete repertoire of shots around the wicket, Viswanath's favourite was the square cut, a shot he often used to great effect against fast bowlers.
