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 Nour El Sherbini
The defining player of the Egyptian age and the youngest women's world champion in history, winning her first World Championship in 2016 at 20 after reaching the final at just 16 in 2012 — the youngest finalist ever. By the 2024-25 season she had assembled seven world titles, behind only Nicol David's record eight, plus multiple British Opens and long spells at world number one that have traded back and forth with her compatriots Raneem El Welily, Nouran Gohar and Hania El Hammamy. Her squash is the clearest statement of the modern Egyptian template: elite movement combined with holds, disguised drops and an ability to attack from positions where earlier generations would have played safe. She won world junior titles before she was 16 and has stayed at the top for more than a decade, an unusual longevity in a system that burns through prodigies, and she is the athlete most likely to carry Egypt's flag into the 2028 Olympic tournament.
