Patrick Reed was, at 23, the youngest winner of a World Golf Championship event when he won the Cadillac in 2014. But who's the youngest man to win a major? asked Robin England
The youngest of all was Young Tom Morris (so called to distinguish him from his major-winning father, Old Tom), who was only 18 years and five months old when he won the British Open at Prestwick in 1869 (there were only eight competitors, though, and the Morrises finished first and second).
Young Tom retained the title the following year, at 19. John McDermott was also 19 when he won the US Open in 1911. Born in Philadelphia, McDermott was the first American-born winner of their Open title.
Francis Ouimet (1913 US Open), Gene Sarazen (1922 PGA) and Tom Creavy (1931 PGA) were all 20 years old.
Coming up to date, Tiger Woods was 21 years and three months old when he won his first major, the Masters in 1997. Jack Nicklaus (1962 US Open), Seve Ballesteros (1979 British Open) and Rory McIlroy (2011 US Open) all won their first majors at the age of 22.
