In September 1964, Graham joined the PGA Tour. His first win was at the 1967 Minnesota Golf Classic at Hazeltine National Golf Club during his third full year on the tour. In 1972, Graham won again at the Liggett Myers Open, followed by the U.S. Open in 1975. Graham had only three wins in fifteen years, and then in 1979, he won three more times in the space of eleven weeks. For this achievement, he won Golf Digest's 1979 Comeback of the Year award.[2]
Graham played on three Ryder Cup teams (1973, 1975, 1977), and was a member of the victorious 1975 World Cup Team. He was inducted as a charter member of the Tennessee Golf Hall of Fame in 1992. During his career, he won over $1.4 million on the PGA Tour and over $600,000 in Senior Tour career earnings.[2]
