Englishman J. Douglas Edgar captured the 1919 championship at Hamilton Golf and Country Club by a record 16-stroke margin; 17-year-old amateur prodigy Bobby Jones (who was coached by Edgar) tied for second. The 1930 Canadian Open at Hamilton was another stellar tournament. Tommy Armour blazed his way around the course over the final 18 holes of regulation play, shooting a 64. Four-time champion Diegel and Armour went to a 36-hole playoff to decide the title. Armour shot 138 (69-69) to defeat Diegel by three strokes.
