King won three Grand Slam singles titles in 1972, electing not to play the Australian Open despite being nearby when she played in New Zealand in late 1971. King said, "I was twenty-eight years old, and I was at the height of my powers. I'm quite sure I could have won the Grand Slam [in] ... 1972, but the Australian was such a minor-league tournament at that time.... More important, I did not want to miss any Virginia Slims winter tournaments. I was playing enough as it was." Her dominance was aided by rival Margaret Court's absence from the tour due to childbirth during most of the 1972 season.
