Career
Diegel was selected for the first four Ryder Cup teams in 1927, 1929, 1931, and 1933. His greatest season was 1928, with wins at the Canadian Open and the 1928 Professional Golf Association Championship, where he stopped the four-year winning streak of Walter Hagen. Diegel defeated him in the quarterfinal to avenge earlier defeats in the 1925 quarterfinal and the 1926 final.
Diegel was a runner-up to Bobby Jones at the British Open in 1930.
Diegel was an excellent ball-striker, but struggled with his putting after joining the Tour. After extensive experimentation, he eventually developed an unusual putting style where he pointed both elbows outwards.
This was referred to as "Diegeling". Diagnosed with throat and lung cancer in 1947, Diegel died at home in North Hollywood, California in 1951 at age 52.
He had taken a position there as a club professional after scaling back his Tour play.
Diegel was inducted into the World Golf Hall of Fame in 2003. Professional Golf Association Tour wins (30) 1920 (1) Pinehurst Fall Pro-Am Bestball (with Tommy Armour).
