Australian Tennis Players, Measured Against Their Own Rankings: Court, Goolagong, Barty

Three Australian tennis players sit at the front of any honest conversation about the women's game in this country: Margaret Court, Evonne Goolagong Cawley, and Ashleigh Barty. They span six decades. They held the world No. 1 spot under three different ranking systems, two of which did not formally exist when the earliest of them was winning. That last fact is the problem, and it is the reason no single page tends to compare them cleanly.

This piece does the comparing. Not to crown one — the record already settles most of that — but to put three careers next to consistent criteria and watch a verdict assemble itself. We will use four: peak ranking and time at No. 1, Grand Slam singles titles, the strength of the competition each faced, and what they did with the WTA system once it existed.

Why comparing them is harder than it looks

The most common question here is simple: who is the greatest Australian woman to play tennis? The honest first answer is that the three best candidates were ranked by machinery that changed underneath them, so the headline numbers are not directly comparable.

The WTA computer ranking did not begin until November 1975. Margaret Court won the bulk of her majors before that — her career ran from the late 1950s through 1973. So when people say Court was "No. 1," they are usually pointing to year-end press rankings and the journalist consensus of the era, not a points table. Goolagong Cawley's career straddles the change: she turned professional before the computer existed and played into the era after it arrived. Barty is the only one of the three whose entire ranked life happened under the modern WTA system, which is why her 121 weeks at No. 1 can be stated with a precision the other two simply cannot match.

That asymmetry matters. We will flag it every time it bites.

Criterion one: Grand Slam singles titles

This is the cleanest measure, because a major is a major regardless of what computer was or wasn't running.

Margaret Court won 24 Grand Slam singles titles, which remains the all-time record across both the amateur and Open eras. Eleven came at the Australian Championships, five at the French, five at the US, and three at Wimbledon. In 1970 she won all four in the same calendar year — the singles Grand Slam, achieved by only a handful of players in history.

Evonne Goolagong Cawley won seven Grand Slam singles titles: four Australian Opens, two Wimbledons (1971 and 1980), and the 1971 French Open. The 1980 Wimbledon is the one historians return to, because she won it as a mother, the first to do so at that event since 1914.

Ashleigh Barty won three: the 2019 French Open, 2021 Wimbledon, and the 2022 Australian Open. She retired weeks after the last of them, at 25, while ranked No. 1.

On raw title count, the order is not close. Court, then Goolagong Cawley, then Barty. But title count rewards longevity and a particular era's scheduling, so it cannot be the whole story.

Criterion two: peak ranking and time at the top

Here the systems diverge, so we report what each system actually said rather than pretending they agree.

The Goolagong Cawley row needs the footnote spelled out. For decades the WTA's records did not credit her with any weeks at No. 1, because of how the 1976 computer rankings were calculated and published. In 2007 the WTA reviewed its historical data and recognized that she had held the top position for two weeks in 1976. So the honest statement is: the record was corrected after the fact, and even now it rests on a reconstruction of a system that was new and imperfect at the time.¹

Barty's 121 weeks is the figure that needs no asterisk. It is the second-longest reign by any player since the WTA system began counting, behind only Steffi Graf, Martina Navratilova, Chris Evert, and Serena Williams in the all-time table — and the longest by any player from Australia, man or woman. When the measure is "dominance the modern system can actually verify," Barty leads decisively.

Criterion three: the field they had to beat

Title counts mean less if the draw was thin. This is the criterion where numbers run out and judgment begins, so we will be explicit about where we stop trusting the data.

Court's 24 majors include eleven Australian titles won in an era when the Australian Championships drew weak international fields. Travel to the southern hemisphere was expensive and slow, and many top players skipped it. That does not erase the eleven, but it does mean a portion of her record was compiled against fields that the French and US titles were not. Her rivalry with Billie Jean King, by contrast, was top-tier and well documented, including the 1973 "Mother's Day Massacre" exhibition that King won.

Goolagong Cawley played squarely inside the King–Evert era and reached eighteen Grand Slam singles finals, losing many to Evert specifically. The seven titles undersell how often she was the second-best player in the world on a given fortnight rather than absent from the conversation.

Barty competed in the deepest, most international, most professionalized era of the three, with a global qualifying pyramid and no soft majors. Her three titles came across three different surfaces — clay, grass, hard — which is itself a marker of a complete game rather than a specialist's haul.

We are not going to convert this into a single number. Anyone who does is guessing with extra steps.

Criterion four: what they did with the WTA system itself

Only Barty lived her whole career inside the modern ranking, so this criterion is partly unfair — but it is also the one most readers actually came to look up, so we will treat it straight.

Barty reached No. 1 on June 24, 2019, and held it across two stretches totaling 121 weeks until she retired in March 2022 while still ranked first. That combination — retiring as the reigning No. 1, at 25 — is rare to the point of being almost unique among players of her caliber.

Goolagong Cawley's interaction with the system was the two reconstructed weeks already discussed, plus a long run inside the top ten that the early computer recorded with varying reliability.

Court's interaction with the WTA computer was minimal, because she had largely stopped winning majors by the time it switched on. To rank her by it would be to measure a sprinter with a stopwatch that started after she crossed the line.

The verdict the numbers assemble

Put the four criteria together and no single player wins all of them, which is the honest result.

Court wins titles outright — 24 is 24, and the 1970 calendar Slam is real. Barty wins every measure the modern system can actually verify, with 121 documented weeks at No. 1 and majors on three surfaces in a deeper field. Goolagong Cawley sits between them as the player most penalized by bad record-keeping and most underrated by raw title count, given eighteen major finals against the strongest rivals of her time.

If forced to one line: Court has the unbreakable record, Barty has the cleanest case under the system we actually trust, and Goolagong Cawley has the strongest claim to having been better than her trophy cabinet says. That is three different kinds of greatness, not one ranking.

A small thing to try this week

Open the WTA's official rankings archive and look up the week of June 24, 2019, then the week of any 1976 date, then try to find a 1970 entry at all. You will hit a wall at the third. That wall — the moment the data simply stops — is the whole reason these three careers can't be reduced to a single number, and seeing it yourself is more convincing than any sentence we could write about it.
