Re: Official Tournament Winners by Event
The Pacific Southwest Championships, Los Angeles, California
In 1971, both Billie Jean King and Rosie Casals defaulted the final at 6-6 in the first set after a refusal to remove a lineswoman with whom King in particular was displeased. This remains the only occurrence of a double default after both players had taken to the court. The tournament was doomed after this occurrence and eventually discontinued in 1974.
1945 Pauline Betz d. Margaret Osborne 6-2, 7-5

Thanks to Rollo and Newmark. I have added it with this change:
1945 Margaret Osborne d. Louise Brough 11-9 6-2
Your final was that of Pacific Coast Championships, held two weeks after.
I have removed "This remains the only occurrence of a double default after both players had taken to the court." because in 1931 in the Eastern Grass Court Championships there was a double default in the final between Elsie Goldsack Pittman and Joan Ridley, with the score 6-3 4-6
