Guy Bertram Wolstenholme (8 March 1931 – 9 October 1984) was an English professional golfer. He had a successful career both as an amateur and then as a professional.
Wolstenholme was born in Leicester, and is the father of Gary Wolstenholme.
As an amateur, Wolstenholme won both the English stroke play and match play championships, the latter on two occasions. He also won several other prestigious titles, including the Berkshire Trophy three times, and the German Amateur Championship in 1956. Wolstenholme remains one the few amateur golfers to have won both The Berkshire and Brabazon Trophies in the same calendar year, the others being Philip Scrutton (1952), Michael Bonallack (1968, 1971), Peter Hedges (1976), Sandy Lyle (1977) and Jeremy Robinson (1987). He played on the Great Britain and Ireland team in the 1957 and 1959 Walker Cup matches and the 1958 and 1960 Eisenhower Trophy, finishing third both years. The highlight of his amateur career came in 1960, when finishing 6th, and low amateur, in The Open Championship at St Andrews.
Wolstenholme turned professional in 1960, and played for several years on the European Circuit, and later the European Tour following its formation in the early 1970s. Despite joining the pro ranks relatively late, he had considerable success, winning 5 tournaments including the British PGA Close Championship and three national opens. He also broke the record for the greatest winning margin on the circuit, when he won the 1963 Jeyes Tournament at Royal Dublin by 12 strokes. He emigrated to Australia in the 1960s and enjoyed more successes, winning several tournaments including the Victorian Open on four occasions.
Wolstenholme played on the Senior PGA Tour (now the Champions Tour) in the United States in 1982 and 1983. He recorded two runner-up finishes, in the 1982 Greater Syracuse Senior’s Pro Golf Classic and the 1983 Daytona Beach Seniors Golf Classic, and ended the season 8th on the money list in 1983.
Wolstenholme died in 1984 after losing his fight against cancer.
