Despite setting a new single-round qualifying scoring record, Collett lost by a fluke in the semifinal of the 1924 U.S. Women’s Amateur when on the 19th hole, Mary Browne’s ball caromed off hers and into the cup. However, that would be her only loss in a year where she won an astonishing 59 out of 60 matches, including her second consecutive Canadian championship. Glenna Collett won the U.S. Women’s Amateur again in 1925, and then reeled off three straight titles between 1928 and 1930.
Between 1928 and 1931, she recorded 16 consecutive tournament victories. She won six North and South Women’s Amateurs, six Women’s Eastern Amateurs, and in between all this she was the runner-up in the 1929 and 1930 British Ladies Amateurs. She also went to France, where she won the French Women’s Amateur. After marrying Edwin H. Vare, Jr. and having two children, Glenna Collett Vare came back in 1934, but lost in the semi-finals to Virginia Van Wie. However, the following year she won her sixth U.S. championship by defeating future star Patty Berg in the finals.
