The case for Heather McKay
The most complete domination in the history of any racket sport. McKay lost exactly two competitive matches in her entire career, both in 1962, and was never beaten again — a run of roughly nineteen unbeaten years. She won sixteen consecutive British Opens from 1962 to 1977, when the British Open was the sport's world championship in all but name, and then won the first two Women's World Opens in 1976 and 1979, giving her eighteen major titles. She also won the Australian championship fourteen times. Her superiority was so absolute that contemporaries struggled to describe her weaknesses, and when she retired she switched codes and won the women's world racquetball championship as well. The standard argument against her is field depth: women's squash in the 1960s was smaller and less professional than the men's game. The standard answer is that she never lost to anyone, for two decades, in any of it.
The case for Nicol David
The most dominant player of squash's fully professional era and the reason the sport has a mass audience in Southeast Asia. David held the women's world number one ranking for 112 consecutive months, from August 2006 to September 2015, the longest unbroken reign at the top in squash history for either sex. She won a record eight World Championships between 2005 and 2014 and five British Opens, thirteen majors in all, and added Commonwealth Games singles gold in 2010 and 2014 along with a long run of Asian titles. Her game was built on relentless retrieval, immaculate length and a movement style so efficient that opponents complained she never looked hurried. She was the first Asian player of either sex to top the world rankings, was voted world player of the year repeatedly, and retired in 2019 as Malaysia's most decorated athlete in any sport.
